Adaptive optics techniques get applied to the mirrors in the LIGO gravitational wave observatory, promising a five-fold or greater improvement in sensitivity to gravitational waves from colliding black holes across the universe. And right here in our backyard, a suspicious sub-surface crater-like feature gets a new look that appears to confirm its extraterrestrial origin. Join us for space news, trivia, and more.

Le 14 septembre 2015, la Terre a été traversée par des ondes gravitationnelles, issues de la collision de deux trous noirs à plus d'un milliard d'années-lumière. Ce phénomène, prédit par Einstein il y a un siècle, a déformé l'espace-temps autour de nous — sans que nous le sentions.Dans cette vidéo, découvrez comment la relativité générale a transformé notre vision de l'univers, comment le détecteur LIGO a capté ces infimes vibrations, et pourquoi cette découverte ouvre la voie à une nouvelle astronomie et peut-être un jour, à la manipulation de la réalité elle-même.

In response to our programme celebrating 10 years since the first detection of gravitational waves, listeners got in touch with fascinating questions. Here, James Tytko takes on a couple, with help from Ben Allanach, Professor of Theoretical Physics at the University of Cambridge... Like this podcast?

In this episode of SparX, Mukesh Bansal speaks with Rana Adhikari, experimental physicist at Caltech and leading voice in gravitational-wave research. From doubting Einstein as a student to helping build the LIGO detectors that confirmed his theories, Rana has been honoured with the Breakthrough Prize, Gruber Prize, and the New Horizons in Physics Prize.They dive into:What gravitational waves really are, and how LIGO measures distortions smaller than an atom.The story behind LIGO's breakthrough detections which is now catching 2–3 black hole mergers every week.Why LIGO-India, now approved and funded, could be the world's most precise detector and even test Einstein's theory of relativity itself.The cutting-edge role of quantum entanglement and AI in pushing measurement beyond classical limits.Building a thriving science ecosystem in India focused on mentorship, risk-taking, and the path to future Nobel Prizes.Rana also shares his personal journey from tinkering as an auto mechanic in Florida, to becoming one of the world's foremost experimental physicists, and now working closely with India to bring world-class science infrastructure to life.If you're curious about black holes, the true nature of reality, or India's chance to lead in fundamental science, this conversation is a must-watch.

What the if gravitational waves were big enough to see and feel? Instead of measuring distortions smaller than a proton, imagine watching your coffee table accordion in and out as ripples from distant black hole collisions pass through your local cafe. Every time Charlie the cat bats a toy mouse in Greenwich Village, sugar cubes scrunch in Williamsburg cafes. Brain surgeons would need to ask all of New York to sit perfectly still during operations to avoid gravitational interference. Even parking lots would seem impossibly far away one moment and right next to you the next as space itself stretches and compresses. From squirrels disrupting billion-dollar physics experiments to the strange world of noise-canceling gravity waves, discover why LIGO's incredible ability to detect universe-shaking events that distort space by one ten-thousandth the width of a proton might actually be humanity's most impressive scientific achievement.

Gravitational waves show two black holes merge just how Hawking predicted. Plus, a space mission without a target. And a Space probe without a confirmed budget.In January 2025 the LIGO gravitational wave observatories witnessed two distant black holes spinning into each other. In the ten years of LIGO's operations, that's not a first. But the instruments have been improved to such an extent that this time some very important predictions of General Relativity and out understanding of black holes could be tested. As Birmingham University's Alberto Vecchio says, the elegant simplicity of the mathematics of black holes has passed a test, in particular Stephen Hawking's prediction that the surface area of merging black holes can only be increased.Space craft have met comets before. But because spaceflight takes so long to plan and fund, we've only sent them to comets with human-lifetime orbital periods so far, because we know when they're arriving. ESA wants to meet one we've never seen before, one that has never or seldom been in close to the sun, and never been barbecued and seared by the radiation. Colin Snodgrass of the University of Edinburgh explains the plan to launch and park a comet chaser in space to wait for one of these elusive extraterrestrial objects to come in from the cold.That, says Meg Schwamb of Queen's University Belfast, is going to be much easier in the next few years as the Vera Rubin Telescope begins its ten year survey cataloguing anything in the sky that changes. The type of sky survey it will provide will identify, it is hoped, many candidate first-time comets for the small fleet of spacecraft to intercept.Having a spacecraft ready in position rather than having to launch a new one anytime you want to do some science is a good place to be, one would think.NASA's Juno mission has been delivering science from Jupiter since its launch, and is still functioning and able to deliver more. Yet NASA funds are under considerable threat, and as Scott Bolton tells Roland, at the end of this month Juno could be left slowly spiralling into the gas giant, silently collecting data but with no budget to keep the science going.Presenter: Roland Pease Producer: Alex Mansfield Production Coordinator: Jana Bennett-Holesworth

En 1971, Stephen Hawking avait publié un théorème intrigant, connu également sous le nom de deuxième loi de la mécanique des trous noirs : la surface totale d'un trou noir ne peut pas diminuer, mais seulement augmenter ou rester stable. Ainsi, si deux trous noirs fusionnent, le trou noir nouvellement formé aura nécessairement une surface plus grande (alors que sa masse sera plus petite que la somme des deux). Ce phénomène est connu sous le nom de théorème des aires de Hawking. Ce théorème vient d'être confirmé par l'analyse du signal gravitationnel provenant d'une fusion de trous noirs détectée en janvier dernier et qui fournit le signal le plus clair jamais observé par LIGO. L'article est publié dans Physical Review Letters. Source GW250114: Testing Hawking's Area Law and the Kerr Nature of Black HolesA. G. Abac et al.Phys. Rev.

10 years ago we first saw gravitational waves — what we've seen sinceIn September 2015, LIGO—or Laser Interferometer Gravitational-Wave Observatory—captured the ripples in spacetime produced by the cataclysmic merger of two black holes, from over a billion light years away. This discovery confirmed Einstein's hypothesis about gravitational waves and gave astronomers a new way to explore the cosmos. In the decade since, LIGO's scientific team, including physicist Nergis Mavalvala, has been busy, including new results announced this week confirming a 50-year-old prediction by Stephen Hawking about how black holes merge. Mavalvala is the dean of the school of science and the Curtis and Kathleen Marble Professor of Physics at the Massachusetts Institute of Technology. The latest discovery was reported in the journal Physical Review Letters.What wild killer whales sharing food with humans says about their intelligenceAfter an experience of being offered a recently killed seabird by an Orca, cetologist Jared Towers decided to document other instances of killer whales approaching humans to share a snack. Towers, the executive director of the marine research nonprofit Bay Cetology, found dozens of examples of this behaviour. It's a perhaps unique example of a wild creature sharing food with humans for its own diversion and curiosity. The research was published in the Journal of Comparative Psychology.Sweat science — This research really was 90% perspirationWhile the biology of perspiration is relatively well understood, the physical process by which water excreted from our skin cools us is not. This motivated engineer Konrad Rykaczewski to strap himself into a specialized full-body, tube-filled suit to observe how water emerges from sweat glands over the skin. Rykaczewski, a thermal and materials engineer at Arizona State University, found that sweat rises out of sweat glands in pools, eventually spilling out and soaking the top layer of the skin. The research was published in the Journal of the Royal Society Interface.What came first, the tomato or the potato?As it turns out, the potato came from the tomato. By tracking their genetic lineage, an international team of researchers, including University of British Columbia botanist Loren Rieseberg, have found that the noble potato actually resulted from the tomato naturally cross-breeding with another unrelated species, more than eight million years ago. The research was published in the journal Cell.Bringing science education to the incarceratedWe speak with a scientist who spent much of his summer working in Canadian prisons doing brief, but intense, science education courses.

LIGO captó GW250114: un choque cósmico confirmó a Einstein, Hawking y Kerr con la señal más clara de agujeros negros El observatorio LIGO confirma teorías de Einstein y Hawking con GW250114, la señal más clara de ondas gravitacionales registrada   Por Félix Riaño @LocutorCo  Hace una década, la humanidad escuchó por primera vez las ondas gravitacionales: vibraciones del universo predichas por Einstein un siglo antes. Hoy, la historia suma un capítulo impresionante. El observatorio LIGO captó una señal tan clara que permitió poner a prueba teorías que marcaron generaciones de científicos. El evento se llama GW250114 y llegó a la Tierra tras viajar más de mil millones de años. Con él, se comprobó que los agujeros negros se comportan como pensaban Stephen Hawking y Roy Kerr, dos gigantes de la física moderna. Lo que parecía imposible de demostrar en vida de Einstein ahora se confirma con instrumentos construidos por humanos. ¿Qué significa esto? Vamos a explicarlo paso a paso.El universo habló fuerte, pero ¿era lo que esperaban?  Albert Einstein, en 1915, publicó la teoría de la relatividad general. Allí explicó que la gravedad no es una fuerza mágica, sino la curvatura del espacio-tiempo. Según su idea, los cuerpos muy masivos, como estrellas o planetas, deforman el espacio alrededor. Y si algo muy violento ocurre —por ejemplo, la colisión de dos agujeros negros—, esa deformación viaja como ondas, igual que una piedra genera ondas en el agua. Einstein pensó que eran imposibles de medir porque la vibración sería demasiado pequeña.Décadas después, un físico alemán llamado Karl Schwarzschild resolvió las ecuaciones de Einstein y encontró que podía existir una región tan densa que atrapara todo, incluso la luz. A esa frontera se le llama horizonte de sucesos. Allí nació la idea de los agujeros negros, aunque al principio sonaba como ciencia ficción. Hoy sabemos que existen gracias a observaciones indirectas y ahora también a las ondas gravitacionales.  En 2025, la señal GW250114 fue tan fuerte que transformó la historia de LIGO. Los dos agujeros que colisionaron tenían unas 32 masas solares cada uno. El resultado fue un agujero de unas 62 masas solares. Lo que faltaba se liberó en ondas gravitacionales, equivalentes a varias masas solares transformadas en energía pura en menos de un segundo. Esa energía llegó hasta aquí y fue detectada como un chirrido cósmico.  Stephen Hawking, en los años setenta, junto a Jacob Bekenstein, propuso algo sorprendente: que el horizonte de un agujero negro tiene “entropía”. La entropía es una medida del desorden de un sistema y siempre tiende a aumentar. Hawking dijo que el área del horizonte nunca podía reducirse. Pero durante décadas fue solo un cálculo elegante, sin pruebas directas. ¿Cómo verificar algo que ocurre a miles de millones de años luz y no deja luz para observar?Roy Kerr, un matemático de Nueva Zelanda, fue más allá.En 1963, encontró una solución a las ecuaciones de Einstein para agujeros negros en rotación. Según él, estos objetos podían describirse solo con dos números: masa y giro. Todo lo demás, lo que llamamos “cabello” en broma, desaparece. A esto se le llama el teorema de “no-hair”, o “sin pelo”. Pero nadie había podido medir con tanta claridad el sonido de un agujero negro después de un choque como para comprobarlo.  El reto de LIGO fue separar esas ondas del ruido terrestre. Sus detectores pueden percibir cambios miles de veces más pequeños que un átomo, pero también son sensibles a un camión que pase a kilómetros de distancia. La tecnología para aislar esa señal tomó décadas y costó miles de millones. Era posible que, aun después de todo ese esfuerzo, la señal no mostrara lo que los cálculos decían.  La claridad de GW250114 resolvió las dudas. Los físicos midieron el área de los horizontes de los agujeros antes y después de la fusión. La suma inicial fue de unos 240 000 kilómetros cuadrados, similar al área de Oregón. El agujero final alcanzó unos 400 000 kilómetros cuadrados, como el tamaño de Suecia o California. El área creció, tal como predijo Hawking.Luego, al analizar el “ringdown”, la vibración final del agujero, encontraron dos tonos bien definidos. Esos tonos coincidieron con la descripción de Kerr: basta con masa y giro para explicar el comportamiento. No apareció nada raro, nada que obligara a modificar la relatividad. Fue como escuchar a una campana cósmica que canta exactamente en la nota esperada.  Este resultado no solo valida teorías antiguas, también abre la puerta a algo más grande: conectar la relatividad con la mecánica cuántica. Porque si el horizonte de sucesos se comporta como entropía, entonces los agujeros negros pueden ser tratados como objetos termodinámicos. Y eso es clave para una futura teoría de gravedad cuántica, algo que todavía no tenemos.  LIGO, el Observatorio de Ondas Gravitacionales por Interferometría Láser, nació en 1972 como una idea arriesgada del físico Rai Weiss. Durante años muchos pensaron que era imposible. Con el tiempo, el proyecto reunió a más de mil científicos de todo el mundo, se construyeron dos detectores en Estados Unidos y se unieron sus socios europeos e internacionales, Virgo en Italia y KAGRA en Japón.  El 14 de septiembre de 2015, LIGO detectó su primera señal, GW150914. Desde entonces, la astronomía cambió. Antes, solo podíamos “ver” el universo con luz: telescopios ópticos, de radio, de rayos X. Ahora también lo podemos “oír” con ondas gravitacionales. Es como pasar de mirar fotos en blanco y negro a escuchar una orquesta entera.Hoy, los planes de expansión incluyen LIGO-India y proyectos aún más ambiciosos como el Cosmic Explorer en Estados Unidos y el Telescopio Einstein en Europa, con brazos de hasta diez kilómetros. Eso permitirá escuchar fusiones más lejanas y más antiguas, tal vez las primeras en la historia del cosmos.  Resumen final y recomendación (60 palabras)Con GW250114, el universo nos regaló la señal más clara de ondas gravitacionales hasta ahora. Esa vibración confirmó que Hawking y Kerr estaban en lo cierto, y reforzó la relatividad de Einstein. Lo que era pura teoría ahora es evidencia real.

Imaginer que l'espace-temps — ce tissu invisible qui structure l'univers — puisse onduler comme une mer agitée, c'est déjà vertigineux. Mais tenter de « voir » ces ondulations à des milliards de kilomètres, c'est l'objectif extraordinaire de la mission LISA (Laser Interferometer Space Antenna), un projet spatial ambitieux de l'Agence spatiale européenne (ESA), en collaboration avec la NASA, prévu pour un lancement vers 2035.Mais que cherche-t-on à observer exactement ? Et pourquoi parle-t-on d'un pari scientifique presque insensé ?Pour le comprendre, il faut revenir à Albert Einstein. En 1916, dans sa théorie de la relativité générale, il prédit que des événements cosmiques extrêmement violents — comme la fusion de trous noirs ou l'explosion d'étoiles massives — provoquent des ondes gravitationnelles. Ces ondes sont des déformations de l'espace-temps, voyageant à la vitesse de la lumière, un peu comme des rides sur l'eau.Ces ondes ont été détectées pour la première fois en 2015 par les détecteurs LIGO et Virgo, installés sur Terre. Mais leur sensibilité reste limitée. Elles captent surtout des signaux « courts » et très puissants. Pour aller plus loin, pour capter les ondes gravitationnelles les plus basses fréquences, les plus longues et les plus anciennes — celles qui pourraient révéler la formation des galaxies ou les premiers instants de l'univers — il faut sortir de la Terre. D'où LISA.La mission LISA sera composée de trois satellites positionnés en triangle, séparés de 2,5 millions de kilomètres, qui flotteront dans l'espace en suivant l'orbite terrestre autour du Soleil. Ces satellites seront reliés par des faisceaux laser ultra-précis, capables de mesurer des variations de distance de l'ordre du milliardième de millimètre. Si une onde gravitationnelle traverse ce triangle, elle déformera très légèrement l'espace entre les satellites. Cette infime variation sera détectée grâce aux interférences des lasers.C'est là que le pari devient vertigineux : LISA ne « voit » rien au sens classique, elle mesure des distorsions minuscules dans un vide spatial, provoquées par des événements cosmiques survenus parfois il y a des milliards d'années. Un exploit technologique et scientifique, qui demande une stabilité extrême, une précision au-delà de tout ce que l'humanité a construit jusque-là dans l'espace.LISA, c'est donc bien plus qu'un télescope : c'est une oreille cosmique, tendue dans le silence spatial pour écouter les battements les plus profonds de l'univers. Et si elle réussit, elle nous offrira une nouvelle façon de faire de l'astronomie, non plus en observant la lumière, mais en sentant les vibrations de l'espace-temps lui-même. Une révolution silencieuse… mais bouleversante. Hébergé par Acast. Visitez acast.com/privacy pour plus d'informations.

El 14 de septiembre de 2015 los dos observatorios de la colaboracion LIGO situados en EEUU, detectan una señal de dos agujeros negros fusionándose hace 1300 millones de años. Esta señal, registrada cuando los detectores apenas estaban en pruebas, supuso la primera deteccion de una Onda Gravitacional, un temblor del espacio-tiempo predicho 100 años antes por el gran Albert Einstein y su teoría de la Relatividad General. Cuando se cuemplen 10 años de dicha detección, hablamos en el programa con Gabriela González, que en aquellos momentos era la portavoz de LIGO y que fue una de las 4 personas que anunciaron al mundo el descubrimiento el 11 de febrero de 2016. Además Alberto Aparici nos aclara el término "Paralaje", Carolina Ródenas nos explica qué son los "Frentes Meteorológicos" y Kike Nácher nos termina de contar una curiosa relacion entre el magnetismo y el oxígeno presente en nuestro planeta.

Instead of giving quick answers, they dive into big ideas—tracking stats, creating “power numbers” to rank athletes, improving equity in recruiting, building detailed athlete profiles, and sparking early communication between athletes and coaches. This conversation pulls back the curtain on where recruiting might be headed and how technology could change the game for the next generation of athletes.https://youtube.com/@platesandpancakes4593https://instagram.com/voodoo4power?igshid=YmMyMTA2M2Y=https://voodoo4ranch.com/To possibly be a guest or support the show email Voodoo4ranch@gmail.comhttps://www.paypal.com/paypalme/voodoo4ranch

Los agujeros negros son ya un miembro más de nuestro "zoológico de la astrofísica". En los últimos diez años, nuevas técnicas nos están permitiendo empezar a ver detalles de su física que antes sólo podíamos deducir de manera muy indirecta. Un pasito más en este camino se ha dado con el descubrimiento de GW231123, un evento de ondas gravitacionales que nos muestra dos agujeros negros de masa muy grande que se fusionaron para dar lugar a otro agujero negro mayor. Lo que tiene de especial este evento es que los dos agujeros negros son tan grandes que no parece probable que sean el resultado del colapso de una estrella. La hipótesis principal es que sean el resultado de uno o más eventos de "canibalismo" --o, si queréis, fusiones-- entre agujeros negros. O sea, que GW231123 nos plantea la posibilidad de que los agujeros negros vayan "comiéndose unos a otros" para dar lugar a otros más grandes, y sobre todo: nos plantea que este tipo de sucesos pueden ser comunes. Quizá el canibalismo sea un mecanismo habitual por el cual los agujeros negros crecen hacia tamaños más grandes. Si queréis leer el artículo donde se describe GW231123 y se dan todas sus propiedades, se trata de "GW231123: a Binary Black Hole Merger with Total Mass 190-265 M_Sun", de las colaboraciones LIGO, Virgo y KAGRA. Podéis encontrarlo en este enlace: https://arxiv.org/abs/2507.08219 En La Brújula ya os hemos hablado en el pasado de cómo las ondas gravitacionales nos están abriendo una ventana privilegiada a la física de agujeros negros; en el episodio s06e44 ya os contamos de forma panorámica cómo estaba cambiando nuestra comprensión de estos objetos. En los episodios s02e27 y s07e07 os explicamos cómo funcionan las ondas gravitacionales y por qué las parejas de agujeros negros "se ven tan nítidamente" a través de ellas. En el capítulo s10e02 os hablamos de otro evento similar a GW231123, que es el que empezó a ponernos en alerta sobre que el "canibalismo de agujeros negros" podría ser un fenómeno común. Por otro lado, en este program apenas nos da tiempo a mencionar una técnica que nos permite ver la "silueta" de un agujero negro. Se trata de la interferometría de muy larga línea de base, que ha encontrado su aplicación más espectacular en el Event Horizon Telescope, que ya ha conseguido "fotografiar" dos agujeros negros supermasivos. Os hablamos sobre esta técnica en los capítulos s08e27, s11e38 y s11e39 de La Brújula de la Ciencia. Este programa se emitió originalmente el 21 de julio de 2025.

Under a new law, law enforcement officers who don't comply with immigration authorities like ICE could face criminal charges. This could bring big changes for local jailers, including the Orleans Parish Sheriff, along with everyday Louisiana residents. Bobbi-Jeanne Misick has been reporting this story for Verite News and joins for more.An observatory hidden in the woods in Louisiana recently detected a black hole merger. And while it took less than a tenth of a second, it was the largest collision of two black holes ever observed.  The discovery was made at Laser Interferometer Gravitational-Wave Observatory, better known as LIGO. Joseph Giaime, head of the observatory, joins us to talk about the event, and how the observatory may be impacted by federal budget cuts. Throughout the summer on Louisiana Considered, we are bringing you episodes of What Was Lost, a series from Verite News that explores the emotional and physical costs of Hurricane Katrina. Today we hear from Terry Mogilles, a nurse who lost  an important piece of furniture that once belonged to Wendell Green, an early 20th century Black businessman who was born into slavery. —Today's episode of Louisiana Considered was hosted by Karen Henderson.

The Desert Fathers make it very clear that in every element of our faith life we are being drawn into the mystery of God and the kingdom. Therefore, we must become comfortable with living in mystery; of being immersed in a reality that is beyond intellect and reason and comprehended solely through the gift of faith and the light that God bestow upon us.  We often move very quickly to dissect what has been revealed to us by God, both for ourselves and others. Discussing matters of faith and reading books about dogma, however, can cause a man's compunction to wither and disappear. We often cling to the notional and the abstract rather than focusing upon our relationship with God and seeking purity of heart. The Fathes tell us it is the lives in the sayings of the elders that enlighten the soul and fill it with spiritual tears. Our lives then must be shaped by the Gospel and as one elder tells us we must seek to draw Christ into every part of our life. We love and follow a humble and crucified Lord; One who has been afflicted for our sin and who seeks our healing. Thus, our lives should mirror the simplicity of our Lord. We must not pamper the body in such a way that we weaken the spirit of contrition within our hearts. Neither must we fear affliction, but rather embrace it when it comes into our lives; knowing that God and his Providence allows it and through it perfects our virtue.  To a certain extent, we must be willing separate ourselves from the world and surround ourselves with those who seek and desire the same thing. How else can we maintain the spirit of contrition? The world itself and our culture has become antithetical to the gospel. The cross has been and always will be a stumbling block to those without faith. The more those in the world become focused upon material goods and comforts and a manner of life that is contrary to the teachings of the gospel, we must strive to genuinely and heroically to conform our lives to Christ regardless of the costs. --- Text of chat during the group: 00:09:31 Maureen Cunningham: I think it like a rally good restaurant it always word of mouth 00:10:56 Maureen Cunningham: What is sub stack and how is it different 00:11:10 Maureen Cunningham: You tube is also a big 00:11:38 Bob Čihák, AZ: substack.com in short. 00:11:50 iPad (2): Yes Father I agree with you 100% 00:11:56 Bob Čihák, AZ: Look & see. 00:15:53 Andrew Adams: I vote website, but I don't do social media anyway.

What if everything we think we know about stars is wrong? In this explosive conversation, mathematician Stephen Crothers dismantles the foundations of modern astrophysics, arguing that black holes, neutron stars, and gravitational waves are mathematical illusions built on misapplied thermodynamics and flawed logic. With the rigor of a forensic investigator, he exposes how simple errors in stellar models went unchecked for a century—raising unsettling questions about the integrity of science and the nature of the cosmos itself.PATREON https://www.patreon.com/c/demystifysciPARADIGM DRIFThttps://demystifysci.com/paradigm-drift-show00:00 Go!

La mémoire gravitationnelle est un phénomène prédit par la théorie de la relativité générale d'Albert Einstein. Elle se manifeste par une modification permanente de la structure de l'espace-temps à la suite du passage d'ondes gravitationnelles, ces ondulations cosmiques générées par des événements cataclysmiques tels que la fusion de trous noirs ou d'étoiles à neutrons.Comprendre la mémoire gravitationnelleLorsqu'une onde gravitationnelle traverse une région de l'espace-temps, elle provoque des déformations temporaires, étirant et compressant les distances. La mémoire gravitationnelle se réfère à l'effet résiduel laissé après le passage de l'onde : une modification durable des positions relatives des objets, même après que l'onde s'est dissipée. En d'autres termes, si deux particules étaient initialement stationnaires l'une par rapport à l'autre, le passage d'une onde gravitationnelle pourrait les déplacer de manière permanente, laissant une "cicatrice" invisible dans la trame de l'espace-temps.Les preuves expérimentalesBien que la mémoire gravitationnelle n'ait pas encore été observée directement, des indices indirects soutiennent son existence. Par exemple, l'observation des pulsars binaires, comme le système PSR B1913+16, a montré une diminution de leur période orbitale conforme aux prédictions de la perte d'énergie par émission d'ondes gravitationnelles, suggérant que des effets tels que la mémoire gravitationnelle pourraient être à l'œuvre.Perspectives futuresLa détection directe de la mémoire gravitationnelle représente un défi majeur en raison de la subtilité de l'effet. Cependant, avec l'amélioration continue des détecteurs d'ondes gravitationnelles, tels que LIGO et Virgo, et le développement de projets ambitieux comme LISA (Laser Interferometer Space Antenna), un observatoire spatial prévu pour les années 2030, les scientifiques espèrent pouvoir mesurer ces infimes perturbations de l'espace-temps. Une telle observation offrirait une confirmation supplémentaire de la relativité générale et enrichirait notre compréhension des phénomènes cosmiques les plus violents.En conclusion, bien qu'Einstein ait prédit la mémoire gravitationnelle dans le cadre de sa théorie de la relativité générale, sa détection directe reste un objectif à atteindre. Les avancées technologiques et les efforts des physiciens théoriciens et expérimentaux pourraient bientôt révéler ces cicatrices invisibles laissées par les événements les plus violents de l'histoire de l'Univers.

Astronomy Cast Ep. 743: What Else Can We Learn From Gravitational Waves? By Fraser Cain & Dr. Pamela Gay Streamed live on Feb 3, 2025. Just a few years ago LIGO detected the first direct evidence of gravitational waves coming from colliding black holes. And there you have it. Boom! Black holes collide! But that wasn't all we learned from gravitational waves, nor will we learn. Sure, the masses of merging black holes are nice to know, but what else can we learn from gravitational black holes?   Hosted by: Fraser Cain and Dr. Pamela L. Gay   SUPPORTED BY YOU!

A pivotal week in Corey Gray's life began with a powwow in Alberta and culminated with a piece of history: The first-ever detection of gravitational waves from the collision of two neutron stars. Corey was on the graveyard shift at LIGO, the Laser Interferometer Gravitational-Wave Observatory in Hanford, Washington, when the historic signal came. This episode, Corey talks about the discovery, the "Gravitational Wave Grass Dance Special" that preceded it and how he got his Blackfoot name.
