Podcasts about Radio astronomy

My guests today are Tommy Jiang and Kevin Harrington.I met Tommy and Kevin while traveling in Patagonia last year.  It was one of those connections that permeate great international travel.  My husband and I were at the end of our month-long excursion and got to enjoy a 35+ hour ferry ride filled with hours of great conversation with them.  Learning about their passions and expertise, I told them about the podcast and invited them to come on!  And now… I get to share this conversation with you!Let me share a bit more about each of them and then we'll jump into our conversation about Psychosynthesis, healing, hypnosis, and more!Tommy is a carpenter and healer currently living in the Columbia River Gorge in Oregon. Tommy's approach to growth and healing in his own life and with clients, combines his background in mindfulness meditation, training as a Psychosynthesis Life Coach through the Synthesis Center in Amherst, MA, and his training as a Professional Hypnotist with the International Certification Board of Coaches & Hypnotists (ICBCH). Tommy aims at a precise approach to coaching and healing work, utilizing what arises in each moment, and following it to integration, wholeness, and profound energy within oneself.Kevin received his PhD in Astrophysics at the International Max Planck Research School for Astronomy and Astrophysics at the Max Planck Institute for Radio Astronomy and the University of Bonn, Germany. He previously received a B.Sc in Astronomy and B.Sc in Psychological Brain Sciences at the University of Massachusetts (UMass), Amherst. Currently he works as a professional astronomer with a postdoctoral research fellowship position at the Atacama Large Millimeter Telescope in northern Chile. He is an internationally recognized Board Certified Coach, and has completed his training in psychosynthesis life coaching through The Synthesis Center since 2015.Tommy and Kevin, thank you for this fantastic conversation!  Thank you for your willingness to connect and engage in meaningful connection both in southern Patagonia and now.  Meeting people like you is one of my favorite things in life and I'm grateful to get to share these pieces of  your wisdom, passion, and beautiful work in the world!You'll find links below to connect with both Tommy and Kevin.Tommy Jiang's Website: www.callofself.comKevin Harrington's Website: https://www.kch-coaching.com/Synthesis Center website: https://www.synthesiscenter.org/Make Life Less Difficult~ Support:buymeacoffee.com/lisatilstra

Dr Laura Driessen takes you 26,000 light-years away, into the centre of our galaxy and beyond in the search for radio stars, supermassive black holes and supernova remnants.Dr Laura Driessen is a radio astronomer who is fascinated with the scale of the universe and the wealth of information it holds, especially in its stars.Her obsession began as a child, looking through her mini telescope on family camping trips at the planets and at comets.But it wasn't until Laura was an undergraduate science student — poring over data from a giant radio telescope to create images of what the centre of our Milky Way looks like — that she got truly hooked into radio waves.Laura now specialises in radio stars at the University of Sydney's Institute for Astronomy.What she is discovering about these flaring beasts could be pivotal in the search for other habitable plants, and possibly alien life. This episode of Conversations discusses space exploration, physics, astrophysics, astronauts, rocket ships, space shuttles, telescopes, radio telescopes, aliens, NASA, Elon Musk, Space X, galaxies, constellations, astronomy.

This week's episode is a Superstars of STEM special edition, with resident Superstar of STEM Dr Susi inviting three of her fellow Superstars to talk about their science on air. Dr Shane is joined in the studio by regular co-hosts Chris KP and Dr Susi, recruiting all listeners for CSIRO's latest citizen science project - the “Chart Your Fart” app. The guests are Dr Sophie Andrews, a Senior Research Fellow and Lead of the Healthy Brain Ageing Research Program in the Thompson Institute at the University of the Sunshine Coast, talking about how lifestyle (like exercise, diet and sleep quality) can impact brain and cognitive health and reduce risk for dementia. The second guest is Dr Charlotte Birkmanis, Shark researcher at a Marine Foundation and Postdoctoral Researcher at the Max Planck Centre in Queensland talking all things sharks, why we need them for a healthy ocean and her children's book ‘Little Shark Lulu Goes To Sleep'. She was followed by Dr Laura Driessen from the Sydney Institute for Astrophysics (SIfA) at the University of Sydney, talking about Radio Astronomy and how she uses data from Australian Radio Telescopes to look at radio stars.

Have you ever looked at the sky at night and wondered about the mysteries of the universe? When most of us are just looking at those bright stars in awe, our guest today would be searching for tiny, minuscule signals that would help unlock the mysteries of the so-called Cosmic Dawn, when the universe went from dark to bright. Eloy de Lera Acedo is an Associate Professor of Radio Cosmology and the head of the Radio Astronomy and Cosmology research group. His background in engineering and thirst of learning about the big science questions have led him to the Cavendish where he is involved in multiple international projects for new radio telescopes exploring a very, very infant universe. So, with Eloy, we talk about the universe of course and how it went from darkness to radiant, but also about childhood curiosity, choosing between technical and theoretical knowledge, and about convincing people.

The new research has been accepted for publication  in The Astrophysical Journal. "Our paper proves that interactions with the neighboring galaxies are responsible for the unusual brightness of early galaxies," lead author Anshu Gupta, an astrophysicist at Curtin University in Australia, told Live Science in an email. "The explosion of star formation triggered by the interactions could also explain the more massive nature of early galaxies." Astronomers discovered the bright gas clouds in data collected as part of JWST's Advanced Deep Extragalactic Survey, which used three of the telescope's instruments to collect infrared images of galaxies before analyzing their spectra." 1835 UK

Foundations of Amateur Radio Cars have been here for well over a century and so has radio. Cars pretty much start when Carl Benz first applied for a patent for his "vehicle powered by a gas engine" on the 29th of January 1886 which is regarded as the birth certificate for automobiles. Radio starts as a thing when Heinrich Hertz proves that radio waves exist in 1888. Since then things have changed, a lot. Today, both these technologies, cars and radio, are everywhere. It's estimated that there are 1.47 billion vehicles on the planet today, in contrast, there are only 44 thousand broadcasters across the globe, serving about 4 billion people, or half the population. So, cars win, right? Not so fast. The Wi-Fi Alliance estimates that there's 3.8 billion Wi-Fi devices being shipped this year alone and there's about 19.5 billion in use. Many of those are mobile phones, so they're not only using Wi-Fi, but GSM, CDMA, 3G, 4G or 5G radios. In many cases they'll have Bluetooth on board and will be receiving GPS information from the currently five constellations in orbit around Earth. Some will even have an FM receiver on board, just to cram another radio inside the same box. To give you a better sense of scale, 2022 saw 4.9 billion Bluetooth devices shipped. In 2010 it was estimated that there were a billion GPS users, today there are more than six billion users being served by GPS systems for positioning, navigation and precision timing. I haven't even talked about other uses of radio, like radar, astronomy, remote sensing, remote control, keyless entry and countless other related and interconnected technologies. So, while there's a car for every five or so people, there's at least two Wi-Fi radios per person and probably more like a dozen radios per person when you start counting those embedded in our daily lives. So, why is it that we have an estimated car enthusiast population of 10% and an estimated radio amateur population of 0.04%? It's not to do with the popularity of the topic. Google trends shows that both cars and radio are consistently trending downwards at about 2% each year since 2016. Radio is consistently twice as popular as cars. When you rank the global popularity of cars vs radio, out of 47 countries, 40 countries care more about radio than cars. South Africa and India care about cars 74% to 26% radio, even New Zealand, 56% vs 44%, cars to radio. At the other end of the scale, Peru, 2% cars, 98% radio. Germany, home for both Heinrich Hertz and Carl Benz, 92% radio, 8% cars. Popular search engines aside, there are other places to look for content. Take platforms like Prime Video, Netflix, Apple TV+ and YouTube. When you search for radio or cars on those platforms it's interesting to see what comes back and explore how relevant it is. I'll encourage you to do the experiment, but as a surprise to nobody, the results are universally woeful but illustrative. Searching for cars returns mostly relevant content, but a search for radio brings back results that have absolutely nothing to do with the topic. Seriously, on Netflix, two documentaries about Pele and Beckham, both famous footballers, neither known for their interaction with radio, rank higher than a documentary on Prime about radio astronomy, cunningly titled, wait for it: "Radio Astronomy". Even the initially promising Netflix result "Amateur" in response to the term "radio" is about a 14 year old basketball player navigating the dark side of sports. While we're at it, just for giggles, I checked the closed captioning for the movie and the word "radio" doesn't appear in the movie, at all. Speaking of representation, Netflix recently published their entire list of content for the first half of the year. The word radio appears exactly once, "John Mulaney: Kid Gorgeous at Radio City" and that doesn't even turn up as a search result when you go looking for "radio". The word "cars" appears 18 times in the Netflix library. So, why is it that topics like "radio", which is demonstrably twice as popular as "cars", and perhaps a dozen times more, let's call it, numerous, in society, has such a poor showing and what can we as connoisseurs on the topic of "radio" do about this? Cars are represented in a plethora of movies, series and shows featuring reviews, mods, restorations and entertainment. There's topic specific channels and social media. There's shops, events, races and so much car merchandise. Is that what's missing in radio, or more specifically, amateur radio, marketing, or is it something else? I'm keen to hear your thoughts. My email address is cq@vk6flab.com, get in touch. For my efforts, I'm publishing my podcast on YouTube and manually working my way through my back catalogue of over six hundred episodes, complete with a, YouTube imposed, limited five thousand character summary of the transcript, just to increase the chances of radio being a relevant search result when someone who's interested in our community comes looking.

Radio astronomy — a subfield of astronomy that studies the sky using radio frequencies — is data-intensive. That poses a challenge for radio astronomers: building and then communicating scientific insights requires significant processing and analytical work. Thoughtworks has been working with Dr. Neeraj Gupta from the Inter-University Centre for Astronomy and Astrophysics (IUCAA) in India to develop solutions to these challenges, including a data processing pipeline, a collaborative platform for analysis and a digital catalog for publishing and communicating research. In this episode of the Technology Podcast Dr. Gupta joins Justin Jose of Thoughtworks India's Engineering for Research (E4R) team as they speak to hosts Rebecca Parsons and Prem Chandrasekaran about their work together. Dr. Gupta explains the benefits of Thoughtworks work from an astronomer perspective, while Justin highlights the challenges of building software solutions in a highly specialized domain.

Join Hugh Ross and Jeff Zweerink as they discuss new discoveries taking place at the frontiers of science—discoveries that have theological and philosophical implications, including the reality of God's existence.   Saving Radio Astronomy The last unspoiled refuge for radio astronomy is the Moon's far side—the most “radio quiet” place in the solar system. There, researchers hope to place four 3-meter antennae to measure the “cosmic dawn,” the radio signal from the universe's first stars that will reveal the characteristics of those stars and evidence for the big bang. However, international lunar exploration could generate so much noise as to eliminate radio astronomy's last unspoiled refuge. In this episode, Hugh discusses how radio astronomers hope to protect this frontier.    References:  Are Telescopes on the Moon Doomed before They've Even Been Built?   Dating Bible Battles Archaeologists have discovered many sites where battles described in the Bible occurred, but determining the dates has been difficult. Recent advances in measuring magnetic field strengths provide a new dating tool. During the tenth to sixth century BCE, Earth's magnetic field experienced fluctuations much larger than seen today. Many of the battles during this time involved burning opponents' cities to the ground, and these fires often heated mud bricks and pottery pieces to temperatures hot enough that the pieces recorded the magnetic field and direction at the time. Scientists have used these magnetic field measurements in artifacts to validate the historicity of many battles recorded in Scripture.

Mars and Venus straddle Gemini. The moon goes as far south as it can this month. Saturn and Jupiter greet us in the morning. Uranus goes through conjunction while Mercury emerges from it. Scientists tried for a few decades to detect radio waves from outer space. Their crude equipment didn't find any. After the discovery of the ionosphere, some concluded that radio astronomy would never be possible. It's been nine decades since a telephone company engineer's happenstance discovery proved otherwise. This is part one in a series on radio astronomy developments that happened unexpectedly.

Recently I had the privilege of interviewing Mia Walker, an engineer and Project Officer at the Curtin Institute of Radio Astronomy in Western Australia. Mia's passion for astronomy is the driving force behind her career in this field, where she has contributed to the development and operation of the Murchison Widefield Array (MWA) radio telescope, a stunning project designed to help unlock the mysteries of the Universe. But without Mia and the team she works with, the astronomers hungry for MWA data would all be staring at blank screens! During this interview, Mia shares her experiences and insights about her work with radio astronomy instrumentation, and projects on the path to the even bigger SKA-Low telescope. Mia speaks about the toughest challenge that radio telescopes face, and how the MWA is overcoming this in the field, which is an extremely remote region of Western Australian outback – where battles with the elements (both environmental and antenna-related) are commonplace. Mia also shares her thoughts on role models in STEM fields, and emphasizes the importance of visibility in encouraging young women to pursue careers in science and engineering. Overall, this interview with Mia is a fascinating insight into the world of radio astronomy and the incredible work being done at the Curtin Institute of Radio Astronomy. Mia's passion and expertise in the field are inspiring, and I am grateful for the opportunity to have learned so much in such a short time from her experiences. You will love looking into this window of Mia's wonderful world!

So you know about dependencies and testing, right? If you're talking to a DB in your app, you have to decide how to approach that with your tests. There are lots of solid options you might pick and they vary by goals. Do you mock out the DB layer for isolation or do you use a test DB to make it as real as possible? Do you just punt and use the real DB for expediency? What if your dependency was a huge array of radio telescopes and a rack of hundreds of bespoke servers? That's the challenge on deck today were we discuss testing radio astronomy with pytest with our guest James Smith. He's a Digital Signal Processing engineer at the South African Radio Astronomy Observatory and has some great stories and tips to share.

For centuries, humans have gazed at the night sky and wondered if any intelligent life forms like us might be out there.  In 2015, the Breakthrough Foundation gave a $100 million grant to the University of California at Berkeley to undertake the most comprehensive search for signals from an extra-terrestrial civilization. Dr. Steve Croft, of the University of California, Berkeley, SETI Center,  describes the project, introduces the many radio telescopes around the world it is using in the search, and explains how modern technology, including AI, is being used to  include more stars, more frequencies (channels) and more ways a signal might be sent.

Interview with astronomer Dame Jocelyn Bell Burnell Jeni talks to the legendary discoverer of pulsars, champion of women in science and Oxford University astronomer about her astronomy career, inspirations, motivations and key discoveries.

with Dr. Dan Werthimer of the University of California, BerkeleyWhat is the possibility of other intelligent life in the universe and how might we detect signals from alien civilizations?  Dr. Werthimer describes current and future projects searching for such signals, including the new $100-million Breakthrough Prize Foundation "Listen" project  to "tune in" on messages that civilizations around other stars might be sending out.  He shows how new technologies are revolutionizing the search for extra-terrestrial intelligence (SETI).  Dr. Werthimer was one of the founders of the SETI@home project, which analyzed data from the world's largest radio telescope using the desktop computers and cell phones of millions of volunteers.Recorded on March 15, 2017

So, while no one may be able to hear you scream in space, with new radio astronomy instruments, scientists are able to tune into the static hiss of distant galaxies.

In this episode, Dr. Victoria Kaspi (McGill University) introduces us to a brand-new mystery in the skies -- superfast bursts of radio waves whose source is still unknown.  These energetic bursts come from all over the sky (and all over the universe,) pack a huge amount of energy, and typically last a few thousandths of a second.  Like a detective in the middle of a case, Dr. Kaspi fills us in on the story of how new observations (especially with the CHIME telescope project which she heads) have been revealing tantalizing new aspects of these bursts, without yet giving us a solution to their ultimate cause.  She shares both the thrills and frustrations of a new phenomenon in science, still in the process of being explored.  Recorded on Oct. 19, 2022.Victoria Kaspi is the inaugural director of the McGill Space Institute and holds the Lorne Trottier Chair in Astrophysics and Cosmology at McGill University.  She is the winner of the 2021 Shaw Prize in astronomy and the 2022 Albert Einstein World Award in Science.

University of Arizona astronomers have identified five examples of a new class of star system. They're not quite galaxies and only exist in isolation. The new stellar systems contain only young, blue stars, which are distributed in an irregular pattern and seem to exist in surprising isolation from any potential parent galaxy. Mysterious ‘Blue Blobs' Reveal New Star System The stellar systems – which astronomers say appear through a telescope as “blue blobs” and are about the size of tiny dwarf galaxies – are located within the relatively nearby Virgo galaxy cluster. The five systems are separated from any potential parent galaxies by over 300,000 lightyears in some cases, making it challenging to identify their origins. The astronomers found the new systems after another research group, led by the Netherlands Institute for Radio Astronomy's Elizabeth Adams, compiled a catalogue of nearby gas clouds, providing a list of potential sites of new galaxies. Once that catalogue was published, several research groups, including one led by UArizona associate astronomy professor David Sand, started looking for stars that could be associated with those gas clouds. The gas clouds were thought to be associated with our own galaxy, and most of them probably are, but when the first collection of stars, called SECCO1, was discovered, astronomers realized that it was not near the Milky Way at all, but rather in the Virgo cluster, which is much farther away but still very nearby in the scale of the universe. SECCO1 was one of the very unusual “blue blobs,” said Michael Jones, a postdoctoral fellow in the UArizona Steward Observatory and lead author of a study that describes the new stellar systems. Jones presented the findings, which Sand co-authored, during the 240th American Astronomical Society meeting in Pasadena, California, Wednesday. “It's a lesson in the unexpected,” Jones said. “When you're looking for things, you're not necessarily going to find the thing you're looking for, but you might find something else very interesting.” The team obtained their observations from the Hubble Space Telescope, the Very Large Array Telescope in New Mexico and the Very Large Telescope in Chile. Study co-author Michele Bellazzini, with the Istituto Nazionale di Astrofisica in Italy, led the analysis of the data from the Very Large Telescope and has submitted a companion paper focusing on that data. Together, the team learned that most of the stars in each system are very blue and very young and that they contain very little atomic hydrogen gas. This is significant because star formation begins with atomic hydrogen gas, which eventually evolves into dense clouds of molecular hydrogen gas before forming into stars. “We observed that most of the systems lack atomic gas, but that doesn't mean there isn't molecular gas,” Jones said. “In fact, there must be some molecular gas because they are still forming stars. The existence of mostly young stars and little gas signals that these systems must have lost their gas recently.” The combination of blue stars and lack of gas was unexpected, as was a lack of older stars in the systems. Most galaxies have older stars, which astronomers refer to as being “red and dead.” “Stars that are born red are lower mass and therefore live longer than blue stars, which burn fast and die young, so old red stars are usually the last ones left living,” Jones said. “And they're dead because they don't have any more gas with which to form new stars. These blue stars are like an oasis in the desert, basically.” The fact that the new stellar systems are abundant in metals hints at how they might have formed. “To astronomers, metals are any element heavier than helium,” Jones said. “This tells us that these stellar systems formed from gas that was stripped from a big galaxy, because how metals are built up is by many repeated episodes of star formation, and you only really get that in a big galaxy.” Gas stripped from galaxy forming...

Don't you love tipping your head back on a clear, dark night, and seeing those silvery stars twinkling above you? We know in our brains that they're giant balls of burning gas, even though they look like fairy dust scattered across the sky. And the reason we know this is because of the science of astronomy. This week we're hearing from an astronomer about the incredible discoveries her field has managed to uncover, and what the next generation of radio astronomy might achieve… right here in Australia.

"We humans are just specks of dust on a slightly bigger speck of dust in the immeasurable vastness of space. We can't cause stars to explode, we don't set the wheels of galaxies spinning, and it is not we who span the vault of heaven above us. But we can marvel at the universe and ask questions about it. We can have faith, hope, and love in this world-and this makes us stardust of a very special kind." —Dr. Heino Falcke We tend to think that science and spirituality are mutually exclusive. But for Dr. Heino Falcke, a belief in something bigger complements his understanding of the universe. Dr. Falcke is a Professor of Astroparticle Physics and Radio Astronomy at Radboud University. He is also the author of Light in the Darkness: Black Holes, the Universe, and Us. On this episode of Reversing Climate Change, Dr. Falcke joins Ross and cohost and Nori advisor David Addison to discuss the origin of carbon molecules and describe what drew him to the study of black holes. Dr. Falcke explains how he captured the first photograph of a black hole through the Event Horizon Telescope project, sharing what he learned from collaborating with 350 other astrophysicists on EHT and how we might apply those learnings to other global challenges like climate change. Listen in to understand why the complex systems of the universe are inherently unpredictable and learn how Dr. Falcke bridges the gap between the scientific and the spiritual world.

Dr. Lisa Harvey-Smith was born in Essex, England, left school at 11 and taught herself at home, where she developed a great passion for astronomy. The home schooling paid off because she went on to earn a Master's degree in Physics with Honours in Astronomy and Astrophysics and a Ph.D. in Radio Astronomy, before embarking on a professional career as an Astrophysicist, Astronomer and Educator (she's a Professor), becoming a world-renowned author, researcher, speaker and easy-to-understand science communicator. Honestly, considering my vast lack of knowledge regarding all-things-astronomy, going in I was a little worried about holding an interesting conversation with someone at the opposite end of the knowledge scale but the Prof. was simultaneously fascinating, funny, real and super interesting.  See omnystudio.com/listener for privacy information.

Dr. Sarah Pearce is Director of the SKA-Low Telescope, soon to be built in Western Australia as part of the $2bn international SKA Observatory. Sarah worked at Australia's national science agency, CSIRO, for 10 years in the fields of space and astronomy, and spent six months in early 2021 as CSIRO's Acting Chief Scientist. Her previous roles included senior science advisor in the UK Parliament and project manager of GridPP, the UK's program delivering computing for particle physics. In 2020, Dr. Pearce was named Telstra NSW Business Woman of the Year and Executive of the Year at the Australian Space Awards. She is a strong advocate for diversity in science and technology. Sarah holds a PhD in X-ray astronomy from the University of Leicester and an undergraduate degree in Physics from the University of Oxford (Worcester College). In this podcast, Dr Pearce shares the latest development of the SKA (Square Kilometre Array) Observatory - an international ‘mega science' radio-astronomy project. The SKAO Is an intergovernmental organisation – the second-ever in astronomy – that was officially launched in July 2021. She highlights that SKA will be the world's largest radio telescope facility of its kind, underpinned by the latest technologies that can help address the exciting cutting-edge challenges in astronomy, including our understanding of the cosmic dawn – the time when the first stars and galaxies in the Universe were formed. She elaborates on the international partnerships and collaborative efforts in the project. It involves 16 countries as well as engineering consortiums across the world, who are coming together to build the two SKA telescopes, being built in remote regions of South Africa and Australia. She explains how the existing precursor radio telescopes in Australia – the Australian SKA Pathfinder (ASKAP) with 36 antennas, and the Murchison Widefield Array (MWA) in Western Australia with more than 4,000 antennas – have contributed to planning for the SKA-Low telescope, the “low” frequency antenna array operating in the 50-350 Mhz band.  Comprising up to 130,000 antennas spreading across 65km of desert, Dr Pearce explains the telescope will be more sensitive, and able to capture images at higher resolution and faster than ever before. Dr Pearce discusses the significance of the selection of the sites in Australia and South Africa – that the Southern hemisphere offers the best views of the Milky Way Galaxy and the remote locations of the telescopes locations ensure minimal radio interference (or “radio quiet”) at these sites. In fact, due to the amount of radio signals generated by human activities, sites visitations are very restricted. With the data captured by the hundreds of thousands of SKA antennas expected to reach 8 terabytes per second, equivalent to more than 100,000 the average speed of home broadband, Dr Pearce points out how the “big data” aspect is also a challenge, in addition to the challenges involve in building the telescopes. Dr Pearce rounds off the podcast by paying respects to the Wajarri Yamaji people, the traditional owners of the land on which the SKA-Low telescope will be built.       Recorded 16th March 2022 1.30pm Australia Western Time Zone/ Singapore Time Recorded 16th March 2022 1.30pm Australia Western Time Zone/ Singapore Time

„Główny urok tej teorii polega na jej kompletności pod względem logicznym” – pisał Albert Einstein w eseju dla The London Times w 1919 roku. Napisał go poproszony o wyjaśnienie czytelnikom znaczenia swojej teorii względności. „ Jeżeli chociaż jedna jedyna wynikająca z niej konsekwencja okazałaby się nietrafna, trzeba by było porzucić całą teorię; wprowadzenie jakiejkolwiek zmiany pociąga za sobą nieuchronnie zburzenie całego gmachu” – kontynuował. Trzeba przyznać, że sprawę postawił zdecydowanie.Po ponad 100 latach od opublikowania Ogólnej Teorii Względności naukowcy wciąż szukają nietrafności jej przewidywań. Teoria grawitacji Einsteina jest również porównywana do konkurencji, której nie brakuje. - Na rynku naukowym istnieje kilkadziesiąt alternatywnych teorii, które wyjaśniają naturę oddziaływania grawitacyjnego – mówi w Radiu Naukowym relatywista, prof. Piotr Jaranowski z Wydziału Fizyki Uniwersytetu w Białymstoku. Porównywania przewidywań tych teorii dokonywał przez ostatnich 16 lat zespół naukowców pod kierownictwem prof. Michaela Kramera z Max-Planck-Institute for Radio Astronomy w Bonn w Niemczech. Obserwowali dwa szybko obracające się pulsary (gwiazdy neutronowe) generujące wokół siebie silne pole grawitacyjne. Znów teoria Einsteina okazała się bezkonkurencyjna. - Nie pojawiły się żadne przekonujące dowody obserwacyjne, które by wskazywały na konieczność zmiany tej teorii – precyzuje fizyk. Po co w ogóle po raz kolejny analizować przewidywania OTW? Choć wszystkie jej przewidywania się sprawdzają, to ta teoria ma swoje słabości. – Są ogromne trudności w połączeniu z mechaniką kwantową – przypomina prof. Jaranowski. Ale tu nie chodzi o żadne „obalanie Einsteina”. – Proszę zauważyć, że Einstein nie „obalił” Newtona. Cała nasza inżynieria opiera się na mechanice newtonowskiej, więc jest ona poprawna. Einstein uogólnił teorię Newtona poprzez uwzględnienie efektów związanych z bardzo silnymi polami grawitacyjnemu – wyjaśnia fizyk. - I sądzę, że w podobny sposób trzeba będzie mówić, gdy zastąpimy klasyczną teorię Einsteina inną teorią klasyczną (czyli nie kwantową – przypis RN), która okaże się być lepsza w tych miejscach, gdzie teoria Einsteina zawodzi, np. w opisie wnętrz czarnych dziur – ocenia. A czy uda się skleić Ogólną Teorię Względności z mechanika kwantową? Czy uda się skwantować grawitację? - Jestem w tej sprawie agnostykiem – mówi prof. Jaranowski.Rozmawiamy również o tym, czy wszystkie rozwiązania równań OTW są fizyczne (głównie dręczę profesora czy da się podróżować w czasie), o tym czy prof. Jaranowski ma swoją ulubioną kwantową teorię grawitacji, o falach grawitacyjnych oraz o tym, że większość fizyków na teorii względności się nie zna.
