- Gravitational Echoes: Just as sound waves can echo off a distant rockface, light waves can echo off of black holes. Renowned researchers Erin Kara and Shep Doeleman join Brian Greene to explore the exotic physics that rules all that happens near the edge of a black hole.
BEYOND EINSTEIN is a 3-part series that explores the wondrous implications of gravity pushed to the extreme, tackling dark energy, black holes and white holes. Renowned researchers join Brian Greene to discuss a range of insights-from confirmed to highly speculative-that extend Einstein’s vision of reality and advance our understanding of fundamental physical laws.
This program is part of the Big Ideas series, supported by the John Templeton Foundation.
Participants:
Shep Doeleman
Erin Kara

Excellent as usual. Can't decide who the best communicator here is, which considering Brian Greene is in the room is quite the achievement. Erin and Shep (and Brian) are such a pleasure to listen to. All of them crystal clear, laser focused and razor sharp. With a healthy dose of wit and human warmth. Thank you WSF for another enlightening and entertaining talk.
crystal, laser, razor
Spellbound. Brian Greene's deftness and erudition, Erin and Shep so wonderfully captivating!
Wow, i dont think ever heard someone even suggest being able to test the presence of a E-R bridge before. Incredible!
Einstein taught me to love physics. Thank you for everything Albert 😊
I have always loved physics and devoured everything astronomy and cosmology related since a very early age. But it took a dedicated and enthusiastic physics teacher to make me realize just how much I love physics and science in general and encourage me to study astrophysics. So let's give all those hard working teachers some love and respect, for they are truly the pillars of the advancement of civilization.
Dr. Greene the formats of the three videos released on or about 3/9/24 were over far too soon. Hope WSF returns to its longer format and discussions. Thank you for the exceptionally expert guests you invite and the brilliant discussions. What a generous, priceless gift! Look forward to future (hopefully longer, please) episodes and to see the WSF live. May you “…live long and prosper…” Prof Greene. ✨
thats really cool. what a black hole sounds like. thanks for doing this :)
The beauty of science is experimental verification of a new idea born of the human mind. Going back to the birth of quantum mechanics and observing hydrogen spectra to show the discrete energy levels of the hydrogen atom. I enjoyed all three lectures arranged nicely by Brian Green and his amazing capabilities to make physics so exciting.
Thank you for making these videos and update us about science.
Brian, the best science comunicator ever existed
You'd think something else if you ever saw him trying to change a lightbulb-hilarious!
Great video! I'm curious to learn about white holes...
Physicist with great personalities, inspiring.
THANK YOU...
DR. GREEN...!!!
Beauty with brains! Wow. I hope she gets a nobel.
4:38
Finding a solution DURING the fighting in WW1.... talk about thinking and working under pressure!! 😅😅
I love the ending music
I heard my heart skip a beat. Damn Kara. 😜
I couldn't figure out this comments until Brian introduced her...
Yep.
That sound was much cooler after the explanation
Wonderful! Brilliant!
Shep Doeleman spent a year in Antartica at McMurdo Station
Enjoy the final music
It would be of great value to include the date on which these events occurred. Seriously.
I swear I've heard about this before...
21:00 The Sound
Super cool 😎 so jealous
Science Rocks! ^.^
Great, glad to sea here Shep Doeleman it is always great to hear him explaining his work. I hope he is fine. I can imagine he 've had some health issue and hope that he is fine now.
Excellent: one question for the expert. Do photons when spinning around black holes gain or loose energy (blue or red shift)?
The Universe is Singing.
If we had the same system of telescopes in the Space focusing on a blackhole, would we get a better picture or result?
Hello fam
would light not ping pong around within the disc before coming out to us, and create "false" echoes? Would there not be many many echoes or are they somehow able to math the noise out? And how would they know which ones were "noise and which one were "music"?
Gotta build off prior models until they all fit together!
1:12 no it's not the first person who considered sperically symmetric star it was b. Datt
It makes me wonder if primordial BHs have some of the first photons ever produced perpetually trapped on that inner most ring?
It is such a shame that because of todays "anti-science" sentiment, many will not get to participate in the excitement of these discoveries. You can feel these researchers' passion come through the screen, and I can't help but feel their excitement rub off on me.
❤
to ask a bat, "if you were flying outside and had to listen for something to not get sucked into, what would it sound like compared to everything else", either drop an audio grenade into a black hole, go fishing with meshuggah bait, or get a really vast room, have a big dude playing bass guitar in one corner, little lady playing a high violin note, different tempos and frequencies... would a black hole be "what not to listen for" or "a lack of what should be there" in what we otherwise should be listening for?
I wonder if the expansion of the universe could be explained by a relationship between black hole "singularities"
I wonder, if thats thruth that light have rouded blackhole miljons years? If I have understand right, so black holes are't stabil, they will grow, and that makes theirs gravitations grow?
Hello from Kazakhstan. If we add NEW 50% of the Michelson-Morley experiment, then it is “possible” to prove the postulates: 1. Light is an ordered vibration of gravitational quanta. 2. Dominant gravitational fields affect the speed of light in a vacuum, its direction and frequency of oscillations.
I need help co-creating an invention. The light in the device has a path of 9000 meters, a volume of 0.4/0.4/0.4 meters.
A deeper understanding of gravity gives you a deeper understanding of the universe. The earth is flat locally the same as the speed of light is the same locally but not on a larger scale. The earth is round on larger scales and the speed of light depends on the measures of time and distance which change depending on the amount of gravity in the surrounding area. This means that distant starlight arrives instantaneously from distant galaxies which aren’t as far away as they appear to us to be with our measures of time and distance and the time is also passing by at a much faster rate since there’s no matter between us and distant galaxies to slow down time or shorten distance according to general relativity which is now an observation and not just a theory. …and the converse of things approaching a black hole look stopped to us because of how slow they are moving.
The changes in time and distance compound the changes in the speed of light as observed from our frame of reference. Do a thought experiment. Hold your hands a foot apart representing 186,000 miles saying “one thousand and one” representing one second while pretending to see an imaginary photon going from one hand to the other. Now expand the distance saying “one thousand and one” as fast as you can. You should notice that the speed of the imaginary photon increases the more distance expands and the more time speeds up just same as the farther away from the center of the galaxy it is. The opposite is also true. Someone moving in the direction of a black hole will seem to us to be stopped. *If you change the size of a cubit you will change the size of the house that you build with it.* 🏠‼️💯
I love science. I really do. But , do you think some things just are what they are? Im not sure that everything, everything, can be explained.
"..looking back in time."
From the future. :O)-
Einstein's dream was to have such a device. Proposal for joint implementation of the invention. You are negotiating with companies that make fiber optic gyroscopes. Technical consultation and payment for the cost of the test device from me
We need; assemble a hybrid fiber optic gyroscope (based on 50% - Michelson's experience 1881-2024). Use a hybrid fiber optic gyroscope and measure; 20, 25, 30 m/sec., car speed in a straight line. As a result of 100% direct experience we will receive the basis for:
Postulate 1. Light is an ordered vibration of gravitational quanta. Postulate 2. The gravitational field controls the frequency and speed of light in a vacuum.
We can save the big 💰s for big science. Gravitational wave detectors are being built in China and India. It is planned to launch heavy space rockets with interplanetary satellites, such as LISA and so on. That's over $4 billion, not counting other resources.
😂 🎨 🧠 😎 ... on the radio 📻 👩🎤 lol
Haytham was one of the greatest Muslim scientist, whose study in optics made telescope possible besides many other discoveries. I wonder if Einstein was compared with him how will they both do?
The things people are doing to advance human knowledge are unfathomable to me. May as well be magic.
The universe is a manifestation of the information that the brain receives and the brain itself is part of that manifestation. Subjects and objects are mere reflections of one another.
Try looking at "The Speed Of Light"..As..??.."The Echo Of Instant Universal Notification"..When you open the cat box door..??.."The Universe Always Know The Answer"..??.."One Billionth Of A Second Before You"...And "The Ring In A Ring"...Or "Circle In A Circle"...??..."Superposition Light Cones"...Bye...
how does all this help humans?
In ways that we cannot even imagine at the current state of our ignorance! That’s fantastic!
Did anyone else hear pac man dying. You have to be a certain age tp get this lol. Thank you as always the science is communicated brilliantly.
We have a wave phase resonant neutrino ocean under pulsation pressure, permeable, refractional, passively entropicm,, and fluid dynamic in nature (our oceans on Earth.. and all permiable spaces under human observation carry the gravitational relativity in close approximation as a visual representation of ½ of the dynamic mechanism that is space-time and gravity under influence - this invaded by inversely resonant electron pairs needlecasting from condensing thermonuclear electromagnetic energy whips (like a lighting weave, or the electron arcs off of a tesla coil under some field of concentration) through resonant action as lightning like wave particle dualistic helixing convergence pairs casting down under neutrino pressure to particle point (this fluid dynamic and strangely attractive as inverse phase conditions one evolving in transversal and energy concentrations, the other in passive refractional pressure and inversely vertexing with Von Karman Vortex streets - neutrino condition vertices showing flip in slipstreaming along side/relatively closer to electron/photon skirting their flow). this weave of inversely resonant, transversing, shearing, entropic, and evolving, dual phase energy states illustrated by electrons, neutrons, photons, protons..ext - wriggling neutrino cymatic conditions to strange attraction, curving and shearing flow in evolving tunneling to eddy, vortex, pulsate, spin/curve, oscillate, and slipstream the neutrino field (or portions relative to human observations of changes in light and, more recently.. radio, electromagnetic, thermonuclear radiant, and gravitational waves under an energetic QCD pulsating weave. These both evolving in spright of one another reinforcing eachother in strange reactions across a closed expanding area (this known simply by the effects seen in identical entropic action resont in change fractionally entangled in refractional transfer permeable in all directions fliping,and flowing as mass, energy, space through time) paralleled by weaves of a paradoxical set. Each inverse in entropic nature. The electron pairs and their inverse convergence(s) through the perfectly acceptable neutrino ocean cymatic in some phases and as a space-time fabric both passively transferring gravitational flow and engulfed inversely as the core spun to matter by phase change so extreme as a combination with energy the act in sets inversely refractional in relative concentrations over time displayed as matter both in attraction and resistance, dependent on velocity and proximity along with a principle partially represented by the cosmological constant.
They refract and influence eachother in a Ying and yang imagination of an inversely evolving field excited transversely by webs, pluming filliaments, galaxies, with that galactic nuclei and quasars, star cores under polar concentration evolved to extreme states of curved and entangled neutrino conditions, combined as resonant spin and pulsation with phased energy condensing and curving flow..this shown in measuring the influence on photon speed across space-time all around us. These observational extremes in measurement and mathematical predictions giving numbers represented closer to infinite nature described by the gravitational influence over mass and energy shown in light illustratiing the movement from and around stars, nebular clouds, heavenly bodies in general, and ultimately photons from or acted upon by the states of entropy hinted under matter moving in relatively refractional space over/through/a part of change in moments of sensing distance and time with paradoxical consequence/influence. A neutrino ocean in relative phase wave resonation we see locally in the wave function, superposition, the cosmological constant, radioactive transfer, thermodynamics, fluid dynamics , super conductivity, gas permiation, vacuum effect through strange attraction and gravitational waves crossed with microwave readings (I would say neutrino isolation readings, but except for maybe Fermilab *hinted by their resent change in focusing on muons under the magnetic moment and neutrino conditions across multiple tanks, technologies, distances in geography, and experiments in the near future with designs on solving the puzzle for fusion* but, we don't seem to understand that neutrinos aren't just zipping into reality and back out. This is just phase bounce or kick and outside of our local resonate flow, we can detect their oscilations). It's the neutrino condition under the wave function in which makes up the isolation tank, the mountain it's stored under, the humans who observe their phase kick, and the space in which energy concentrated itself and changed neutrino phase into matter which hums through existence to evolving in proximity to orientate these subject theories to exist and be tested in the first place. The way in which we assign applications of theory reinforcement or lack thereof, through granting value at a whim and ignoring this value at another is mind numbing. Humans created these concepts in the first place. They are agreed assignments of representation and value of shared observations in correlation similar across all accurately described accounts of human existence through time. It's aggregate by principle, yet, we talk eachother into greater complexity, obscurity, and confusion.. half the time too busy trying to find representation in similar visual experience of a more general and easily conceptualized expression in order to relate foreign theories to individuals lacking a basic/elementary foundation over knowledge of physics and cosmology in painstaking repetition - that we forget the underlying goal is aggregate to finish. We're trying to overcomplicate simple process by focusing too fine. Our own resonant organic computation is key. The more we row together, the quicker we'll marry these terms over relative agreement. We see the fluid dynamics and ignore it's permiation transfer across all fields because of 1 word and our backwards observation of the involved boundary.. "vacuum" (when we understand this is QCD in a neutrino ocean under inverse phase change in variable action with and/or through/around one another with existence inside refractional exchange
Sorry Einstein is not wrong it's quantum physics if I'm a betting man, that would be my bet.
Since the black holes are very luminous, why was this difficult?
just remember that there is nothing inside Black hole and after they will discover this.
Thank you for your incredible insight. You must be a Professor on this subject?
I am not
i am unknown student of physics which my mind is swimming in the space.
if anybody solved the mystery of double-slit experiment they can solve the Black Hole mystery as well.
Your proof of this?
Why the fake audience clapping? This is just a presentation in a studio, right? Or is this actually live?
It’s certainly live, and there’s an actual audience usually. During Covid, they did things remotely using zoom. You can hear people coughing at times too, so it’s an actual audience
To me it sounds like the intro is in an empty hall but the panel discussions is with a live audience in the same hall as they usually do except during COVID like mentioned above
I would pay to be in the audience
First!
sheps hair game still worst in the multiverse
What, in 1930's Penrose told Einstein that BH is possible. Is Green out of his mind?
😌🪽Oh…
😔but how I wish I could play…🥺🪽🫳🏽
