Lori discusses the scientific basis for the heart's magnetic energy, referencing figures like Bruce Lipton and the Institute of HeartMath, and relates it to concepts from physics, such as the Einstein-Rosen bridge, which illustrates the connection between different points in space and time.Key points include:Heart as a Portal: Lori explains that the heart is not just a physical organ but a magnetic energy center that can be viewed as a portal connecting us to higher realms of love, joy, and bliss.Chakra Significance: The heart chakra, colored in both green and pink, represents the connection between the earthly realm and higher emotional states. Green symbolizes earthly connections, while pink represents love and higher frequencies.Accessing Higher Frequencies: Lori emphasizes that by opening this heart portal, individuals can embody elevated states of being and incorporate these energies into their physical form, allowing them to serve others more effectively.Call to Action: She invites listeners to explore this concept further through her mentorship programs and classes, encouraging them to reach out for consultations to deepen their understanding and practice.---

I wormhole, noti anche come ponti di Einstein-Rosen, sono teorizzati come tunnel che collegano due punti distanti nello spazio-tempo, permettendo un passaggio rapido tra essi. La spiegazione di come funziona un wormhole si basa sulla relatività generale di Einstein. Secondo alcuni documentari, i wormhole potrebbero teoricamente esistere e essere usati come macchine del tempo. Per costruire un wormhole stabile, sarebbe necessaria materia esotica con energia negativa, che impedirebbe al tunnel di collassare. Nei film come "Interstellar", i wormhole vengono rappresentati come passaggi praticabili per viaggi interstellari e temporali. Il concetto di wormhole come macchina del tempo implica che, manipolando uno degli ingressi con velocità relativistiche o posizionandolo in un forte campo gravitazionale, si potrebbe creare uno sfasamento temporale tra le due estremità. Questo permetterebbe di viaggiare nel tempo entrando in una estremità e uscendo nell'altra in un'epoca diversa. Tuttavia, sebbene l'idea sia affascinante, non esistono attualmente prove che i wormhole esistano nella realtà. Inoltre, costruire un wormhole con le tecnologie attuali è oltre le nostre capacità. La possibilità di viaggiare nel tempo attraverso i wormhole rimane quindi un affascinante tema di ricerca teorica e speculazione scientifica. FONTI • De-Chang Dai and Dejan Stojkovic.

Viajeros en el Tiempo Técnicas para Viajar al Pasado Nuevas investigaciones Un nuevo estudio, realizado 22 de noviembre de 2021, afirma que la materia podría pasar intacta a través del horizonte de sucesos de un agujero de gusano. Éste nuevo estudio afirma que los agujeros de gusano permiten los viajes espaciales. Según esta investigación, los agujeros de gusano son  mucho más estables de lo que se pensaba  y la materia podría atravesar una barrera que antes se creía infranqueable para llegar a otro punto del universo al instante. Nadie ha observado nunca un agujero de gusano aunque, en teoría, es posible que aparezcan en cualquier lugar y encajen dentro de la Teoría de la Relatividad de Albert Einstein. De hecho, el nombre científico de los agujeros de gusano es “Puente de Einstein-Rosen”. El segundo es el apellido del físico israelí-estadounidense Nathan Rosen, quien desarrolló el concepto junto con Einstein.. Estudiemos lo expuesto …

The wormhole theory postulates that a theoretical passage through space-time could create shortcuts for long journeys across the universe. Wormholes are predicted by the theory of general relativity. But be wary: wormholes bring with them the dangers of sudden collapse, high radiation and dangerous contact with exotic matter. We asked physicist Robert Kehoe, some frequently asked questions about wormholes. Robert Kehoe Professor, Department of Physics, Southern Methodist University Robert Kehoe is a physicist currently studying the nature of the accelerating expansion of the universe. He is a lead researcher on the Dark Energy Spectroscopic Instrument (DESO), which is creating a far-reaching map of our universe. His research has also included work in particle physics, including contributing to the discovery of the Higgs boson, a previously only theoretical subatomic particle that allows for things to have mass. Are wormholes theoretically possible? A wormhole is thought to be essentially a tunnel from one place in space to another. When you have a massive object in spacetime, it basically creates a curvature of the spacetime in the nearby region. As you get more and more mass, we expect that that curvature becomes more and more extreme. We think such objects occur in the universe, and they are what we call a black hole, where light cannot escape due to this extreme curvature of spacetime. We think what happens is, at some point, if the mass of an object becomes large enough, the other forces of nature besides gravity can't support the matter, and it becomes a black hole. You could think about this as one side of a wormhole. Could you have a situation in which the curvature is extreme enough to connect up with something analogous on the other side somewhere else in spacetime? Theoretically, that could be true. Has a wormhole ever been found? No. We have a substantial amount of evidence for the existence of black holes.  But there's been no wormholes found.   Are there different types of wormholes?  There are different theoretical implementations of our theory of gravitation, called general relativity, that would describe wormholes with somewhat different properties. For instance, one of the big distinctions in the types of wormholes that are described are whether or not they are traversable — by that I mean, whether you can go from one end to another.   When was the wormhole theory created? Wormholes were first theorized in 1916, though that wasn't what they were called at the time. While reviewing another physicist's solution to the equations in Albert Einstein's theory of general relativity, Austrian physicist Ludwig Flamm realized another solution was possible. He described a "white hole," a theoretical time reversal of a black hole. Entrances to both black and white holes could be connected by a space-time conduit. In 1935, Einstein and physicist Nathan Rosen used the theory of general relativity to elaborate on the idea, proposing the existence of "bridges" through space-time. These bridges connect two different points in space-time, theoretically creating a shortcut that could reduce travel time and distance. The shortcuts came to be called Einstein-Rosen bridges, or wormholes. "The whole thing is very hypothetical at this point," said Stephen Hsu, a professor of theoretical physics at the University of Oregon, told our sister site, LiveScience. "No one thinks we're going to find a wormhole anytime soon." Wormholes contain two mouths, with a throat connecting the two, according to an article published in the Journal of High Energy Physics (2020). The mouths would most likely be spheroidal. The throat might be a straight stretch, but it could also wind around, taking a longer path than a more conventional route might require. Einstein's theory of general relativity mathematically predicts the existence of wormholes, but none have been discovered to date. A negative mass wormhole might be spotted by the way its gravity affects light that passes by. Certain solutions of general relativity allow for the existence of wormholes where the mouth of each is a black hole. However, a naturally occurring black hole, formed by the collapse of a dying star, does not by itself create a wormhole.  

Appearing under a pseudonym created to keep the author and his family safe from harm, Adam Gamal served in the most elite units in the US Army, deployed more than a dozen times, and finally retired in 2016. Currently an international consultant for a security organization, in the first half, he shared his account of how America fights its battles abroad in the modern age of terrorism, as well as offered commentary on various conflict zones. He described how he emigrated from Egypt to the US as a young man in order to experience greater freedoms, and then after 9-11 enlisted in a secretive military group referred to as "the Unit," which he said has been responsible for preventing many terrorist attacks throughout the Western world. Gamal rose through the ranks and became one of the Unit's most skilled operators.He offered an analysis of the Israel-Gaza conflict and suggested that Hamas staged their attack as a way to derail the Abraham peace accords between Israel and various Gulf states because they believed if that happened, the Palestinian cause would be forgotten about. Gamal argued that a two-state solution is the only way to resolve the problem in that region. He also gave his take on other areas of geopolitical concern, including China, Russia, and Iran, and emphasized the importance of having diversity in the US armed forces.-----------Author Mike Ricksecker has been researching unexplained phenomena worldwide for over 30 years and has appeared on several popular television shows. In the latter half, he discussed his ongoing work on the nature of time, dimensions, and the possibilities of time travel, along with stargates, magnetic anomalies, and ancient Egyptian mysteries. He detailed his Stacked Time Theory, which is the idea that all time, past, present, and future are here right now. "Each of those moments has its own frequency to it," he explained, and if we can tap into those different frequencies, "we can move up and down that stack at will." Such occurrences can play out in our everyday lives, he added. For instance, two moments can bleed into each other in what has been called a "time slip" that is sometimes mistaken for a ghost or haunting.Precognitive dreams and premonitions demonstrate an aspect of time travel, he remarked, and they may be fostered by a change in our brainwave states while asleep. Ricksecker delved into the concept of stargates or portals and how people may travel or disappear into them and related this to the Einstein-Rosen bridge, the scientific theory that wormholes exist out in space. The symbolism of stargates is seen at temples in ancient Egypt with their massive stairways, he added. Describing what he called "Egypt's Area 51," he said it's a military installation with unfinished or remnants of pyramids that were dug out, and there are rumors that the site contains an ancient circular stargate.

Cub Kuker Supernatural Podcast EP347 Ancient Astronaut Theory, popularized by Zecharia Sitchin, is generally considered a wild theory. Mainstream traditional faith leaders largely view these interpretations of biblical events as allegorical rather than literal “celestial visitations” yep, this theory continues to stir the lines of the curious. For the sake of pure curiosity I will dive deep into these events from the perspective of Sitchin's ideas and some of my own: 1. Garden of Eden as an Outdoor Laboratory: According to the Ancient Astronaut Theory, the Garden of Eden wasn't just a paradise for Adam and Eve but rather an extraterrestrial laboratory where advanced beings conducted genetic experiments. These beings, often referred to as the Anunnaki, allegedly manipulated the DNA of early humans, shaping them into intelligent beings. The forbidden fruit, then, might have been a metaphor for the knowledge of procreation bestowed upon humans by these extraterrestrial genetic engineers. 2. Tower of Babel as a Rocket-ship: In the Ancient Astronaut interpretation, the Tower of Babel was not just an ambitious construction project but a colossal ancient rocket-ship. The story in Genesis describes humans attempting to build a ‘tower' to the heavens, and Sitchin's theory suggests that this could have been a misguided attempt to reach the Anunnaki's home planet or a space station. The confusion of languages that followed could be seen as a divine intervention to thwart humanity's extraterrestrial ambitions. 3. Jacob's Ladder as a Spacecraft Entrance: The biblical story of Jacob's Ladder, where Jacob dreams of a ladder reaching to heaven with angels ascending and descending, could be reinterpreted as an encounter with an extraterrestrial spacecraft. In this view, the ladder may have represented a technologically advanced transportation device used by the Anunnaki or other advanced beings. The angels could be the beings themselves, coming down to interact with humans. 4. A Day to God as 1000 Years as Einstein-Rosen Bridge Time Travel: The concept of a day to God being like 1000 years, as mentioned in Psalm 90:4, could be explained through the lens of Einstein-Rosen bridges, commonly known as wormholes. According to the Ancient Astronaut Theory, these advanced beings might have had the ability to manipulate time and space, allowing for time travel or communication across vast distances in what seems like a short period to them but longer on Earth. 5. Noah's Ark as a DNA Bank and Advanced Technology Shelter: In the Ancient Astronaut interpretation of the Noah's Ark story, the ark becomes a high-tech vessel designed not just for saving pairs of every animal but also preserving the genetic diversity of various species. The flood, in this theory, could be a cataclysmic event or even a deliberate act by the extraterrestrial beings to cleanse the Earth and reset their genetic experiments back to the original status quo of earth and its natural evolutionarily trajectory. *These interpretations are purely creative and theoretical, so please always do your own research in regards to any theory. × I Explore Supernatural Myths.

Falo con Olga Osorio, directora da longametraxe "SALTA". "Aínda que é unha historia moi fantástica, con viaxes no tempo. É moi realista e a xente sae moi emociada do cine, porque se recoñece". "É unha película que reivindica a importancia de entender de onde ves, de que quen te criou". "Hai un uso bastante narrativo da lingua, sobre todo na personaxe de Mabel Rivera". SALTA! é unha película que nace a partir da curtametraxe Einstein-Rosen (ver curtametraxe ), que Olga rodou en 2016 cos seus fillos Óscar e Teo, que se chaman, non por casualidade, como os protagonistas da película. A curtametraxe nace como unha broma familiar, sen ningún tipo de ambición, pero percorreu medio mundo, gañou máis de sesenta premios internacionais e sobre todo, foi a constatación de que desde a aparente simplicidade contiña algunhas ideas que conectaban moi ben co público de todo o mundo. O tema esencial, que xa está na curta, é a relación de dous irmáns, probablemente una das máis especiais que existen. A película fala sobre os roles familiares e tamén acerca do difícil que pode chegar a ser entendernos e comunicarnos coas persoas que máis queremos. O ingrediente das viaxes no tempo permítenos incorporar os 'e se' e tamén facer un exercicio de nostalxia. A este asunto central súmanse outros que tamén están na película e cos que creo que os espectadores van poder conectar como a vellez ou a ciencia. Trailer "SALTA": https://www.youtube.com/watch?v=Z49-b9GFhyY Sinopse: A Coruña, xullo 1989. Óscar e Teo (13 e 10 anos) son dous irmáns, moi distintos entre si, que viven nun modesto piso de barrio.

SON OF MAN Permutations of בראשית/Bereishit which underlie the seventy Tikunim Tikun #3 mentions that "בראשית" contains "ברית אש/britesh/Covenant [of] fire"—whoever guards the Covenant (i.e. circumcision, family purity and related matters) is saved from the fire of hell; and whoever is involved in Torah and guards the Covenant is called an "adam/man" fit to "sit" in the house (Isa. 44:13) and "see" the "ראש בית/rosh bayit/Head of the House," that is, the King, Hashem. Next I saw Joshua the high priest standing before the angel of the Lord, with Satan standing at his right hand to accuse him. The Lord said to Satan, “May the Lord rebuke you, Satan! May the Lord, who has chosen Jerusalem, rebuke you! Isn't this man like a burning stick snatched from the fire?” Now Joshua was dressed in filthy clothes as he stood there before the angel. The angel spoke up to those standing all around, “Remove his filthy clothes.” Then he said to Joshua, “I have freely forgiven your iniquity and will dress you in fine clothing.”” Zechariah‬ ‭3‬:‭1‬-‭4‬ ‭ ““Is it by your understanding that the hawk soars, and spreads its wings toward the south? Is it at your command that the eagle soars, and builds its nest on high? It lives on a rock and spends the night there, on a rocky crag and a fortress. From there it spots its prey, its eyes gaze intently from a distance. And its young ones devour the blood, and where the dead carcasses are, there it is.”” ‭‭Job‬ ‭39‬:‭26‬-‭30‬ “Indeed, you are my lamp, Lord. My God illuminates the darkness around me.” ‭‭Psalms‬ ‭18‬:‭28‬ ‭NET‬‬ “I was watching in the night visions, “And with the clouds of the sky one like a son of man was approaching. He went up to the Ancient of Days and was escorted before him. To him was given ruling authority, honor, and sovereignty. All peoples, nations, and language groups were serving him. His authority is eternal and will not pass away. His kingdom will not be destroyed.” Daniel‬ ‭7‬:‭13‬-‭14‬ ‭NET‬‬ “For just like the lightning comes from the east and flashes to the west, so the coming of the Son of Man will be. Wherever the corpse is, there the vultures will gather.” Matthew‬ ‭24‬:‭27‬-‭28‬ ‭NET‬‬ RED FOX Seeing the shadow deception internal (near) and external (far off) WORMHOLE Yes and amen promise and oath merged priest and king A wormhole, also known as an Einstein-Rosen bridge is a theoretical method of folding space and time so that you could connect two places in space together. You could then travel instantaneously from one place to another. As Einstein taught us, gravity isn't a force that pulls matter like magnetism, it's actually a warping of spacetime. The Moon thinks it's just following a straight line through space, but it's actually following the warped path created by the Earth's gravity. And so, according to Einstein and physicist Nathan Rosen, you could tangle up spacetime so tightly that two points share the same physical location. If you could then keep the whole thing stable, you could carefully separate the two regions of spacetime so they're still the same location, but separated by whatever distance you like. I believe the Lord had this come across for my purview this morning. Walking on water or cloud riding is some serious stuff but what if it's not…what if it's just the joy of being delighted in by the Father in the promise and oath the yes and the amen of a wormhole?

I know, I know - time travel is everyone's favorite dream. Whether in sci-fi movies (Tenet, Primer), TV shows (Star Trek, Doctor Who), or books (End of Eternity, Kindred), we've all dreamed of time-traveling to the future, of partaking in a completely-changed version of our universe. Unfortunately, though, today's episode is here to crush your hopes and dreams: we'll talk about why time travel is (mostly) a bust, and why most common time travel solutions (wormholes, Einstein-Rosen bridges, etc) are unlikely to occur. So grab your tissues, get grounded on Earth, and get ready to have a good cry - let's talk about the truth behind time travel today. 

My special guest is here tonight to discuss how he thinks our sun is a wormhole and what's been observed from it.     A wormhole (Einstein-Rosen bridge) is a hypothetical structure connecting disparate points in spacetime and is based on a unique solution of the Einstein field equations.[1]  A wormhole can be visualized as a tunnel with two ends at separate points in spacetime (i.e., different locations, points in time, or both).  Wormholes are consistent with the general theory of relativity, but whether wormholes exist remains to be seen. Many scientists postulate that wormholes are merely projections of a fourth spatial dimension, analogous to how a two-dimensional (2D) being could experience only part of a three-dimensional (3D) object.[2]  Theoretically, a wormhole might connect extremely long distances, such as a billion light years, short distances, such as a few meters, different points in time, or even other universes.[3]  In 1995, Matt Visser suggested there may be many wormholes in the universe if cosmic strings with negative mass were generated in the early universe.[4][5] Some physicists, such as Kip Thorne, have suggested making wormholes artificially.[6]     The Casimir effect shows that quantum field theory allows the energy density in certain regions of space to be negative relative to the ordinary matter vacuum energy, and it has been shown theoretically that quantum field theory allows states where energy can be arbitrarily negative at a given point.[28]Many physicists, such as Stephen Hawking,[29] Kip Thorne,[30] and others,[31][32][33] argued that such effects might make it possible to stabilize a traversable wormhole.[34]The only known natural process that is theoretically predicted to form a wormhole in the context of general relativity and quantum mechanics was put forth by Leonard Susskind in his ER = EPR conjecture. The quantum foam hypothesis sometimes suggests that tiny wormholes might appear and disappear spontaneously at the Planck scale [35]: 494–496 [36], and stable versions of such wormholes have been suggested as dark matter candidates.[37][38] It has also been proposed that if a tiny wormhole held open by a negative mass cosmic string had appeared around the time of the Big Bang, it could have been inflated to macroscopic size by cosmic inflation.[39]  Image of a simulated traversable wormhole that connects the square in front of the physical institutes of the University of Tübingen with the dunes near Boulogne-sur-Mer in the north of France. The image is calculated with 4D raytracing in a Morris–Thorne wormhole metric, but the gravitational effects on the wavelength of light have not been simulated.[note 1]  Lorentzian traversable wormholes would allow travel in both directions from one part of the universe to another part of that same universe very quickly or would allow travel from one universe to another. The possibility of traversable wormholes in general relativity was first demonstrated in a 1973 paper by Homer Ellis[40] and independently in a 1973 paper by K. A. Bronnikov.[41] Ellis analyzed the topology and the geodesics of the Ellis drainhole, showing it to be geodesically complete, horizonless, singularity-free, and fully traversable in both directions. The drain hole is a solution manifold of Einstein's field equations for ae, modified by the vacuum spacetime inclusion of a scalar field minimally coupled to the Ricci tensor with antiorthodox polarity (negative instead of positive). (Ellis specifically rejected referring to the scalar field as 'exotic' because of the antiorthodox coupling, finding arguments for doing so unpersuasive.) The solution depends on two parameters: m, which fixes the strength of its gravitational field, and n, which determines the curvature of its spatial cross sections.

In today's episode, we're going to  talk about Stargates. For those unfamiliar with what a stargate is, a stargate is a theoretical Einstein–Rosen bridge portal device that allows practical, rapid travel between two distant locations. At several ancient megalithic sites across the Earth, there are thought to be remnants of these stargate devices that supposedly belonged to and were used by ancient humans. Modern day science has proven that these devices should theoretically work and that practical applications of such technology could rewrite how we travel and what travel limitations humans really have. In movies and books such as Stargate, Avengers, Monsters, Inc, Buck Rogers, John Carter of Mars and literally, hundreds of others of movies, books and comics -- humans have been depicted to use these stargate portal devices to travel to worlds unknown. Traversing the stars, visiting other habitable planets, traveling to different parts of the earth simply by walking through a doorway. Today, our episode talks about these supposed stargates, both anciently and in modernity -- asking if mankind has truly been able to travel the universe, or, if it's all an illusion of mankind's wishful imagination. Our guest today is Tim R. Swartz. He's an Indiana native and an Emmy-Award winning television producer/videographer, and is the author of a number of popular paranormal books including The Lost Journals of Nikola Tesla, America's Strange and Supernatural History, UFO Repeaters, Time Travel: Fact Not Fiction and more. Tim is also the host of the show "Exploring the Bizarre" along with Timothy Green Beckley. He's also appeared on ancient aliens and other paranormal television shows.

A Stargate is an Einstein–Rosen bridge portal device within the Stargate fictional universe that allows practical, rapid travel between two distant locations.[1] The devices first appear in the 1994 Roland Emmerich film Stargate, and thereafter in the television series Stargate SG-1, Stargate Atlantis, and Stargate Universe. In these productions, the Stargate functions as a plot device, allowing the main characters to visit alien planets without the need for spaceships or any other type of technology. The device allows for near-instantaneous travel across both interstellar and extragalactic distances. “Wikipedia”.

As we continue to study what the Bible says about the Abyss, we consider that the Bible indicates that heaven is -up,- and hell is -down,- as we saw when we looked at Romans 10-6-7.--While we speak of heaven as up, and hell as down, the Bible hints that those who have died are aware of what is going on here on earth -Revelation 6-9-10-, and part of the torment of hell is that it is not unlike walking on a dark street and observing through an open curtain a joyous celebration from which we are forever locked away -Matthew 8-12- 22-13- 25-30- Luke 16-27-28-.--When God judged the rebels Korah, Dathan, and Abiram, he caused the earth to open its mouth like the maw of a great beast and swallow them alive into the Pit, not simply a burial, but into Sheol -------- itself -Numbers 16-26-34-.--While the Lord Jesus' body lay on a stone slab within a rock-hewn grave, he himself descended into -the heart of the earth- -Matthew 12-40-. And after he conquered death, he ascended into heaven eclipsed from sight by a cloud -Acts 1-9-.--Where are these places- The Lord Jesus is with us when we gather in his name -Matthew 18-20-, and when we worship on earth, we are surrounded by an innumerable company of angels and the spirits of believers who have died and gone on to heaven -Hebrews 12-1, 22-24-.--Some of the theories of quantum physics such as -wormholes- -Einstein-Rosen bridges- illustrate how it is possible to pull the Biblical data together.

Este programa explora a construção dos conceitos científicos que são apresentados em Dark, uma aclamada série alemã de ficção, suspense e drama que está disponível no canal de filmes via streaming Netflix. Dark é muito conhecida pelo alto grau de complexidade do seu roteiro, que traz diversos elementos da física. Mas o que será que realmente é ciência por trás da série? Como é que os autores conseguem escrever uma história que envolve conceitos difíceis ligados de forma tão complexa? Quem vai ajudar as jornalistas Caroline Maia e Mariana Hafiz a responder essas perguntas, fazendo uma imersão ao universo de Dark são o físico Willian Abreu e o escritor de ficção científica Fábio Fernandes.  E aqui você tem o roteiro completo para acompanhar o programa. Seja bem vindo à física criativa de Dark, o episódio 102 do podcast Oxigênio.  ******************************** Willian: A própria série continuamente faz referências a artigos científicos, como por exemplo os artigos de F. Englert e R. Brout, de 1964 e do próprio Higgs, fazendo uma associação, uma menção rápida ao bóson de Higgs Fábio: O roteiro é fundamental, porque como viagem no tempo é uma coisa que não existe, a gente pode brincar com teorias Willian: Para que o bóson de Higgs fosse evidenciado, foi necessário a construção de um enorme acelerador de partículas na Europa, chamado LHC. Enfim, fica claro que não é possível que uma usina nuclear possa gerar isso. Fábio: Na ficção, o importante é o que Rolland Barthes chamava de "efeito de real": tem que provocar na pessoa - no leitor ou no espectador - a sensação de que aquilo ali é real ou poderia ser real Willian: É realmente uma liberdade 100% artística e que não tem nenhuma relação com o que é de fato representado no universo. Fábio: Usar só o artifício de botar a história no futuro não basta, tem que saber escrever a história mesmo. Saber como escrever a narrativa. E aí é uma coisa que não é ficção científica, é da literatura ou do roteiro.   Caroline: Dark é a primeira série original alemã da Netflix, de drama, suspense e ficção científica. Ela foi eleita a melhor série da Netflix, superando as famosas Stranger Things e Black Mirror. Com 3 temporadas, a série é reconhecida pelo enredo sombrio e super complicado que envolve viagem no tempo. A primeira temporada estreou em dezembro de 2017 e a terceira e última saiu mais cedo esse ano, em julho de 2020.  Mariana: Por envolver viagem no tempo, a série faz várias menções a temas científicos de física. Inclusive o primeiro episódio já começa com uma fala de Albert Einstein sobre o significado de tempo. Mais especificamente, Dark aborda muitos conceitos de fissão nuclear, por conta de uma usina nuclear, que é central no enredo. Caroline: Buracos negros, Ponte de Einstein-Rosen, O paradoxo de Bootstrap, Boson de Higgs...esses são alguns dos elementos da física que a série explora. Mas será que ‘essa ciência’ que a série mostra é real? As coisas que acontecem lá poderiam mesmo acontecer na realidade? E com essa complexidade toda envolvendo física e ficção científica, como é que os roteiristas constroem histórias como Dark?  Mariana: Pra responder essas perguntas, entender melhor a física por trás de Dark e a construção do roteiro de séries como essa, o Oxigênio de hoje mergulha no universo dessa já premiada série. Eu sou a Mariana Hafiz. Caroline: E eu sou a Caroline Maia. E começa agora o episódio 102, A física criativa de DARK. Mariana: Em primeiro lugar, para construir um enredo complexo como o de Dark, o escritor de ficção científica precisa de muita imaginação. Como explica Fábio Fernandes, escritor do gênero, para escrever uma história assim o trabalho é semelhante ao de alguém que escreve uma ficção utilizando elementos históricos, só que com mais criatividade.

Un agujero de gusano o puente Einstein-Rosen, se puede visualizar como un túnel con dos extremos, cada uno en puntos separados en el espacio-tiempo. Y estas ubicaciones son, diferentes puntos de tiempo. O definiéndolos con más precisión, son túneles en el espacio-tiempo curvo. En la reunión del mes de abril del año 2019 de la American Physical Society en Denver EE.UU., el físico de la Universidad de Harvard, Daniel Jafferis, y sus colegas han demostrado que los agujeros de gusano pueden existir. Él y sus colegas basaron su teoría en una configuración diseñada por primera vez por Albert Einstein y Nathan Rosen en el año 1935 Estudiemos el relato…

If advanced civilizations are real, how would they get here? The speed of light is torturously slow on a cosmic scale, so is it possible that the famed Einstein-Rosen bridge, aka wormhole, is a technology that can be mastered? Frank and Mike have a look at some fun and weird takes on this intriguing topic...

Okay, this theory is way out there...WTF Moments: A Stargate is an Einstein–Rosen bridge portal device within the Stargate fictional universe that allows practical, rapid travel between two distant locations. Many ancient cultures speak of portals to other worlds and gateways to star systems where their “creators” reside. The theory is that an alien race, called the "Annunaki" came to earth through this Stargate and taught the Sumerians how to do a bunch of shit thousands of years ago.Apparently there are several of these Stargates around the world and their existence has been hidden from the public from secret governments for years.The conspiracy theory is that we started the war in Iraq to get a hold of this particular Stargate, because we though that Saddam Hussein had relevant information on this Stargate/the Annunaki and the US got pissed.This guy actually wrote a professional paper on this theory - read it here.Quite a few people actually believe this...Check out our website!Contact us!Support the show (https://www.patreon.com/join/cocktailsandconspiracies?)

This week we’re joined by an editor from Nature magazine to talk some real, hard science. No science fantasy, no science fiction, these movies are pure science baby. First up is the fictionalised Scopes Trial adaptation Inherit the Wind (1960) to determine whether we are men or monkeys. Second up is endless rounds of decontamination in the face of The Andromeda Strain (1971) and its virulent alien nature. We finish on Jodie Foster listening intently to the chaos of interstellar static as she tries to make Contact (1997).Also: Sixty-year-old ice cubes. Bewitched! Mr. Teeny. Hyper-chicken. The American psyche 3: Son of American psyche. Judas Goat. Jactitation. What a difference a day makes. Nuke it from orbit. In your face Resident Evil (2002). Chekov’s Nuke. Panspermia. Ryan Gosling Won’t Eat His Cereal. Alec Trevelyan. Stene stealing. We love William Fichtner. Einstein-Rosen bridge. Sphere (1998). We play a game of “Let’s Science the Shit Out of This!”

Time travel is the concept of movement (such as by a human) between certain points in time, analogous to movement between different points in space, typically using a hypothetical device known as a time machine, in the form of a vehicle or of a portal connecting distant points in time. Time travel is a recognized concept in philosophy and fiction, but traveling to an arbitrary point in time has a very limited support in theoretical physics, and usually only connected with quantum mechanics or wormholes, also known as Einstein-Rosen bridges. In a more narrow sense, one-way time travel into the future via time dilation is a well-understood phenomenon within the frameworks of special relativity and general relativity, but advancing a large amount of time is not feasible with current technology. The concept was touched upon in various earlier works of fiction, but was popularized by H. G. Wells' 1895 novel The Time Machine, which moved the concept of time travel into the public imagination, and it remains a popular subject in science fiction.

A wormhole or “Einstein-Rosen bridge” is a hypothetical topological feature that would fundamentally be a shortcut connecting two separate points in spacetime. A wormhole may connect extremely long distances such as a billion light years or more, short distances such as a few feet, different universes, and different points in time. A wormhole is much like a tunnel with two ends, each at separate points in spacetime. For a simplified notion of a wormhole, space can be visualized as a two-dimensional (2D) surface. In this case, a wormhole would appear as a hole in that surface, lead into a 3D tube (the inside surface of a cylinder), then re-emerge at another location on the 2D surface with a hole similar to the entrance. An actual wormhole would be analogous to this, but with the spatial dimensions raised by one. For example, instead of circular holes on a 2D plane, the entry and exit points could be visualized as spheres in 3D space. TRCKLST : Goth-Trad feat.

Programa Vivir Rodando 89 (31 Octubre 2016) Invitada: Ángeles Gómez Hace unos días llegó a su fin el viaje interestelar que supuso el 49 Festival Internacional de Cinema Fantàstic de Catalunya. Edición marcada por Star Trek, el gran nivel del cine asiático, Arrival, Christopher Walken o la lluvia, que fue protagonista casi toda la semana. Como todos los años, el Festival de Sitges ofreció una variada muestra de lo que la temporada en cine de género nos ha dejado. Y como es habitual Vivir Rodando le dedica un podcast realizado conjuntamente con Feedback Ciencia (Ángeles Gómez). En este programa 89 de Vivir Rodando hablaremos sobre películas destacadas del certamen, la retrospectiva de Red Planet Marx, el premio Minotauro concedido a José Antonio Fideu y algunos cortos con temática científica que se proyectaron. En concreto Einstein-Rosen, El sueño espacial y L.O.P.E. Un nuevo amanecer científico. Además se podrán escuchar las voces de Takashi Miike (Terra Formars), José Antonio Fideu (Premio Minotauro por Los últimos años de la magia), Jaume Pujadas (El cor del pi negre) y Adam Nimoy (For the Love of Spock).

The observed accelerated expansion of the universe is successfully parameterized by a cosmological constant. However, since this parameter in Einstein's equations is not protected against quantum corrections, the observed and theoretically expected value vastly differ, thus giving rise to the cosmological constant problem. In this thesis, the issue is addressed by embedding our universe--represented by a brane--in a six-dimensional bulk spacetime, where the cosmological constant plays the role of a brane tension, which then no longer needs to imply an expansion of the three apparent spatial dimensions; rather, it curves the extra space and hence stays hidden from a brane observer. In this context, the crucial question is whether this so-called degravitation mechanism may be implemented in a phenomenologically viable and 't Hooft natural way. Corresponding answers will be given in the case of four different models. The main part of this thesis has its focus on the 6D brane induced gravity model--a higher-dimensional generalization of the Dvali-Gabadadze-Porrati model--according to which a brane with sub-critical tension curves the bulk into a cone of infinite spatial extent. First, it is shown that the model is free of ghost instabilities only if the tension is not unnaturally small. This in turn opens a window of opportunity to study theoretically consistent modified cosmologies. In this context, it is shown that a homogeneous and isotropic brane acts as an antenna that emits and absorbs cylindrically symmetric Einstein-Rosen waves. We encounter two interesting types of solutions--sub-critical ones, which feature dynamical degravitation but are incompatible with observations, as well as compact super-critical ones, which still might be phenomenologically viable but certainly not technically natural. While this clearly shows that the cosmological constant problem cannot be solved in a 6D version of the model, our results point towards higher-dimensional constructions as the remaining playground for future research. Next, we introduce a new two-brane model where a thick super-critical brane curves the extra space into a cigar that closes in a microscopically thin sub-critical brane, representing our universe. In the case both branes only host a tension, we derive fully analytic solutions, which correspond to a de Sitter phase on our brane and are hence phenomenologically promising. Unfortunately, as a fine-tuning of the brane tension is required, they are not technically natural. The failure is attributed to the compactness of the extra space. To further exemplify the virtue of infinite volume extra dimensions, we devise a hybrid model where the brane is wrapped around an infinitely long cylinder of microscopic width. This construction turns out to be the minimal setup that features bulk waves as a dynamical ingredient of a modified cosmology. We find that, due to the existence of an infinitely large dimension, the system admits a degravitating solution. While being conceptually interesting, a supernova fit shows that the corresponding 4D cosmology cannot describe our universe. Finally, we turn to the model of supersymmetric large extra dimensions that had been claimed to successfully address the cosmological constant problem. Here, a Maxwell flux stabilizes the extra space that has the shape of a rugby ball. We critically review the corresponding mechanism, and find that a vanishing brane curvature--as required by the degravitation idea--is only ensured by a scale invariant brane sector, which however leads to an unavoidable parameter constraint due to a flux quantization condition. In a second step, we generalize our analysis to solutions that admit a de Sitter phase on the brane. Provided the model parameters are not tuned, we find that either the brane curvature or the volume of the extra space exceeds its phenomenological bound by many orders of magnitude. Our results significantly narrow down the search for solutions of the cosmological constant problem in the realm of extra-dimensional scenarios. In particular, models with infinite volume extra dimensions are found to offer a working mechanism, which yet requires refinement to comply with the observational bounds.

In this thesis, we investigate the gravitational consequences of theories in which the four spacetime dimensions of our universe are augmented by two spatial extra dimensions. More specifically, the focus is on braneworld scenarios, where our world is confined on a hypersurface in the higher-dimensional bulk, allowing the extra dimensions to be large or even infinite. Our main motivation for studying such models is that they could in principle be able to solve the cosmological constant (CC) problem via degravitation: the CC only curves the extra space, leaving the brane geometry flat. A major difference to the simpler case of a codimension-one brane is that here, gravitational waves can be emitted into the bulk, even at the 3D homogeneous and isotropic level, as is relevant for cosmology. Therefore, we first analyze the question how an outgoing wave boundary condition can be implemented, which is necessary in order to obtain a closed set of modified Friedmann equations predicting the cosmological on-brane evolution. We find that a potential tool from the literature, provided by a certain decomposition of the Weyl tensor - while being applicable to plane gravitational waves - fails for cylindrical waves. This failure is related to the fact that it is already impossible to locally separate incoming from outgoing linear cylindrical waves (on flat spacetime), as we demonstrate by explicitly deriving the corresponding nonreflecting boundary condition, which is nonlocal in time. We then consider a generalization of the Dvali-Gabadadze-Porrati (DGP) model, containing an additional compact on-brane dimension on top of the one infinite codimension. Since here the 3D maximally symmetric brane emits plane waves, the Weyl tensor criterion can be used to exclude incoming bulk waves, and we derive the resulting Friedmann equations. If the compact dimension is stabilized, DGP cosmology is recovered, but we find indications that the stabilization should break down when the CC starts to dominate, which would lead to additional, potentially interesting late time modifications. If, on the other hand, the compact direction is allowed to expand freely, there are dynamically degravitating solutions - which, however, lack a 4D regime and are thus ruled out, as we demonstrate by fitting to supernova data. Next, we turn to the codimension-two version of the DGP model. By numerically solving the full nonlinear coupled bulk-brane system for cosmological symmetries on the (regularized) brane, we show that in some region of parameter space, a CC - but also any other fluid component - gets degravitated dynamically, and a static geometry is approached via the emission of Einstein-Rosen waves. For other model parameters, pathological super-accelerating solutions are encountered. The origin of this unstable behavior is traced back to a tachyonic ghost mode which is identified in this parameter region by studying linear metric perturbations around a nontrivial pure tension background. While confirming the ghost result on Minkowski from the literature, we gain the important insight that the ghost disappears if the brane tension is large enough, thereby reconciling the model with the physical expectation of a healthy low energy effective theory. Unfortunately, the healthy region is again incompatible with an appropriate 4D gravity regime, and therefore ruled out phenomenologically. The preceding analysis only covered sub-critical brane tensions, meaning that the deficit angle of the exterior conical geometry is less than 2π. In the following chapter, we investigate super-critical tensions (first in 4D), and find that the (regularized) static solution is no longer stable. Instead, the axial direction expands at an asymptotically constant rate, and the exterior geometry (which is necessarily compact) takes the form of a growing cigar. We are able to derive an analytic relation between the expansion rate and the tension, which - when adapted to the 6D setup - only yields a (small) constant shift in the CC, and can therefore not help with the CC problem. Finally, the case of two finite codimensions is analyzed within the model of supersymmetric large extra dimensions (SLED). First, we show that - contrary to recent claims in the literature - a brane-localized flux cannot help avoiding the fine-tuning (which is here imposed by flux quantization) in order to obtain 4D flat solutions, basically because only scale invariant brane couplings ensure a flat brane. Next, we ask if a more realistic model with a finite brane width and scale invariance breaking couplings could still be successful by predicting a small enough (albeit nonzero) 4D curvature, but find a negative answer: If the extra-dimensional volume is within its currently allowed range, both effects give way too large contributions to the curvature, unless the brane width were many orders of magnitude below the bulk Planck length, and again some sort of fine-tuning were invoked.
