I'll never forget when this discovery was made, the professors at my university took my class to the common room and handed out copies of the paper, explaining to us how groundbreaking it was. Only two years earlier I had found out about gravitational waves and lamented that I would probably not live long enough to see them verified. Science never fails to impress and amaze.
Yes, feel those gravitational waves pulling earth towards them! Careful though, they might suck you off the face of the earth! If they are able to reach that far, maybe the next one might be closer and gravitationally pull everything off earth! Scary stuff!
@Huawei is a criminal organization. LoL I was being sarcastic 😂, I find it really annoying when people use words to describe something that just doesn't work in its favour, we all know the word gravity and we know that it's the thing that is keeping us from floating away from our planet, but then someone comes up with the word gravitational waves! Now I don't know about you, but to me it's saying that there are waves that will draw you into the centre of where the waves are coming from. That's like saying that it's anti gravity! Which doesn't exist along with many other things that people talk about as if they understand what they are but in reality they really don't have a clue. Oh and regarding gravity being the weakest field in the universe! Gravity isn't a constant so we can't say that it's the weakest field in the universe, the more active a planet and is, the stronger it's gravitational field.
@Huawei is a criminal organization. it would be easier but also incorrect. Unfortunately I have the ability to see things for what they are. Measuring what they call gravitational waves here on earth from somewhere far out in space is a very time consuming job! As you should know that waves propagating from a central point increase in diameter the further out the waves travel, so that means that by the time that wave hits earth, it's going to look like a slow rise in signal and the only way to know if anything actually was measured is to collect data for many years and replay the data at a faster speed so that you can see that there was an actual change taking place. Kinda like looking at the temperature variations over the last 100 years on earth. Gravitational waves are measured as a frequency, if you look at the wave propagation from above, the frequency is much higher at the source but as they move outward they stretch and change to a lower frequency... When an AC signal is so large it could easily be seen as a DC signal so basically back here on earth, it could be so huge that it just looks like a slow rise in activity and not the way that the people who measured it as a fast frequency sweep. It almost looks like the signal was fabricated on a frequency sweep generator. I guess that their funding is now secured.. Maybe I know something about physics or maybe I don't but if you just accepted everything that you have been taught and told, then you might as well be religious where your not supposed to question anything. I didn't realize that people had to obtain a PhD to become so stupid, thankfully I missed out on that opportunity.
@Huawei is a criminal organization. Wow! Target! Really! They couldn't afford me and the school's that you attended just weren't good enough for me either. It clearly shows how bad your education is by your remarks. It's not your fault, you thought that by attending those institutions that you will be intelligent enough to put me down but I'm afraid it's not working. I know everything that you know and then some. If you really had any intelligence you would have made an effort to listen when someone else talk's and then you would question why is it that they are thinking what they are thinking, but no! Your the one who read all those books, your the one who attended all those lectures, your the one who holds that piece of paper that claims you know something. Are you but hurt that the most successful and wealthy people in this world are all high school dropouts? How is it possible that people like you armed with your piece of paper can't do better than a high school dropout? What is it that you were not taught in school that's preventing you from being successful at anything? I know what it is, you rest on your piece of paper as if it actually means something, your not the only person who studied so there's hundreds of other people just like you. The thing that you are missing is that one thing that you weren't taught at school, and that's the ability to see that which no one else can see even though it's in plain sight! And it's so easy when you have studied electronic engineering, geology, history and just about every other subject that you care to mention. No one forced me to learn anything because no one had to, it comes naturally to me. I'm so smart that I can give you a real plausible alternate theory on any topic that you could care to mention. I know all current theories and concepts but most of them are incorrect and that means most of what you know is also incorrect too. You make sure that you frame your piece of paper and place it where your uneducated associates can see it because you like them don't really know as much as you think that you know. LoL frequency and magnitude, don't you mean frequency and amplitude, looks like you might want to learn some more about Electronics because you are going to need it. The nerve of some people, the minute someone has a theory that they weren't taught, they label them as uneducated lol when they are the ones that don't know.
@@PeterMilanovski hi there, just to clear up a couple of misconceptions for you, (bearing in mind, I do have a physics education but I'm not an expert on g waves). A brief explanation of Einstein's general relativity describes gravity as the curvature of spacetime due to massive objects. The more massive, the more curved spacetime becomes around the object and other objects (whilst also curving spacetime themselves) follow straight lines but in a curved spacetime around the object, so it looks like their trajectories are curved by it. This leads to notions of orbits as being straight lines but in curved spacetime. If two objects are extremely compact and massive (e.g. black holes or neutron stars) and are mutually orbiting each other, their orbit gradually decays. The closer they get, the faster they spin around each other due to conservation of angular momentum. Eventually they merger together, but just before they do, they are rotating extremely fast around each other. This high speed and large mass lerturbs spacetime in a repeating pattern (a gravitational wave) that propagates put into the universe at the speed of light. While the strength of the wave does gradually dissipate as it travels, the frequency is conserved so it doesn't need to be measured over a long time. Also, with regards to the strength of gravity, we are referring to the gravitational constant which is very weak and this means you need very high masses to feel gravity. For example the electromagnetic repulsion between the tiny electrons in your feel and the floor is enough to overcome the gravity of the entire planet, hence you don't fall through the ground.
I translated this video to Brazilian Portuguese, but I don’t see any subtitles available… People should see this, be aware of the beauty science can achieve. The idea that Einstein almost 100 years ago predicted that we should be able to see this waves, albeit difficult, 1 billion dollars later and a group of a 1.000 working together to make this happen, is outstanding, really remarkable. I used the word ‘beauty’ because this seems to me to be closest you can get to the subjective experience we have when contemplating art, but in this case you don’t need to see or hear anything, just understand and think about it.

A Hollywood producer was on a flight sitting next to Cameron Diaz; she was describing this crazy movie she was making, "Being John Malkovich". The producer sheepishly admitted he was financing it. She laughed and laughed. The money guys behind these very expensive experiments should also be congratulated for persevering when the scientist weren't even sure there was anything to find with these tunnels in the middle of nowhere.

Three different detectors saw the same thing.The scientists on this panel have been working on this for up to 40 years.Who among us would be that scientifically patient and rigorous about the results.They deserve great respect.And no one but those in the field can truly focus and understand what was accomplished.We can be skeptical but given time I believe this will be a normal part of science.Gravitational waves are here to stay.
This is the longest RUclips video I've watched and felt wanting more. I'm glad there are many breakthroughs that happened recently, Higgs Boson, BEC, and Gravitational Waves. All these can be related. Einstein still continues to fascinate.
Congratulations on the 2017 Nobel Prize. I already watched this presentation last year when it was first published .. it's still informative and entertaining
The two physicists beside Brian won the Nobel price in physics in 2017, a year after this video was released. The recipients were Rainer Weiss, Barry C. Barish and Kip S. Thorne "for decisive contributions to the LIGO detector and the observation of gravitational waves."
This is a huge achievement in the history of science. And yet there are so many people out there who have no idea about this, and if you ask them about LIGO and gravitational waves, they will just look at you with a confused expression. And if you do explain it to them, they will usually just give you a "that's nice, dear" kind of reply.
Brian Greene your linguistic skills are excellent. Not to mention your perfectly clear train of thought and ability to convey it without a pause, hiccup, or stutter are to me truly impressive. You are a cultural gem for your devotion to science and its dissemination. Thank you very much!

I am not saying he's wrong here, but he needs to understand that experimental Physics is different from Theoretical Physics...methods and results of different experimental means and ways need to be correlated before one can claim a Proof ...without verifying the results of other experiments and depending the inference on only just two findings of the similar experimental setup & means can be a case of False Positive too...
Rajiv B You're right, he is talking about experimental physics in this video. I guess i was thinking of the first I'd heard of him which was though his book 'The Elegant Universe' ; String Theory or 'M Theory' is definitely more theoretical than experimental.
I love that the numerical part goes on the longest, speaking for myself personally I never hear enough about the nitty gritty of the math, which lets admit is the language of nature and physics. Also such an interesting look at Einstein’s field equations
So, here's a guy who's devoted his career to string theory and is careful to put a caveat on someone else's implicit assumption that string theory is correct. Where else do you see this? In politics? In religion? That one moment is a little jewel hidden in the rest of this excellent presentation.
Exactly. Short term, self serving bullshit that doesn't get supported by evidence in the long run doesn't help you and actually hurts you in the long run. Religion and politics is the opposite. Even Einstein, among the greatest scientists ever, made fairly large errors which he openly admitted. That humility is what is so refreshing about science for me too.
I liked your comment;don't know how many physicists make the mistake of confusing theory with fact; there's a wonderful combative as well as cooperative element to all discussions on the nature of reality which may, however, seduce us into such confusions. For an experimental scientist, this error might seem simply egregious - particularly as no-one's come up with a currently feasible way of testing this elegant & powerful theory. Even if they confirmed it, it would remain falsifiable as this is key to theoretical improvement & in any case a fundamental part of the scientific method. So it's indeed good to hear someone who really likes string theory say 'Well, I really don't know;' come to think of it it's sometimes sold as the only plausible basis for a unified theory. A little premature lol. Politics and religion sigh groan swear.
I see it diferent. I think you would be correct if Greene was the one to came up with the string theory, but was the LIGO dude who did came up with the string stuff predictions.
HELP: The description educators use to describe space bending via gravitational forces troubles me because we use the analogy of a trampoline and a heavy object in the middle to describe such phenomena. However, the description is taking place in a semi-2D grid and we know, obviously, reality is in 3D. So in all, the waves do not travel just in the x-axis but in a complete 360 degree coverage from the origin. I am probably not making sense, but the trampoline description does not fulfill my mind; I just want to see space bending in a 360 degree coverage but that will not look as appealing as the former analogy. Anyways thanks!
The 2D grid is just a representation since it is very difficult to describe in full 3D, yes, the gravity wave propagates in 3D, if you rotate the 2D grid in 360 degrees both laterally and longitudinally, that would be the true representation, but as I said, this is a difficult view, therefore represented in 2D.
Yes, you see, we've simply collapsed one of the 3 ordinary dimensions. Choose whichever you wish to collapse. Then try to "uncollapse" it ... envision the curvature of spacetime in 3d, then move to 4.
Thank you for this video and to brian to simplfy things. Without him you'll easily lost the track and he helps a lot to understand many things discussed.
Why can't we have something like this for prime time TV? No teen drama about getting laid, just some basic or complex science about our universe; on what channel in what part of what world can I find this without commercials? RUclips is the only place I've seen this (with a touch of ad block) but why is this not mainstream programming? Ehh, I digress, have at 'er! Good stuff, I need more!
I’m always amazed by male or female scientists that kind of appear to know part of how nature works in a very tangible way not just wander around this world to get ends met.
Dude the waves themselves are flat - they fit in to the theory .... lol theyre just a little too flat for us to see lol our 3d eyes make it 3d but its really flat lol
I greatly admire those who devote themselves to something at a young age that takes so long to come to fruition. I certainly didn't have the patience for it until recently.
It's very humbling to hear from a Nobel prize winner that he couldn't teach relativity and how difficult it was for him to understand the operational details of the first experiment on gravitational waves. And also how this difficulty led him to come up with a simplier and more precise idea for detecting those waves.
Two things: First, an absolutely fascinating discussion among very intelligent people. Two, Brian Greene is a genius and the best host/moderator of WSF discussions possible. He clarifies complicated issues easily and allows panel members to talk without continually interrupting them.
All diagrams of Gravitational waves I have ever seen are basically a wavy line but what we dont see or explained is how gravity goes in every direction so instead of a wavy line we would actually see a Wavy Bubble.
I am totally impressed at the human spirit's ability to continue to see awesome things in the mind's eye and continue until it is realized by observation.
Thank you very much to Mr Brian Greene (moderator) to explain what the mathematician nerds have a hard time explaining, by treating the audience with respect.
just wanted to say, I agree, Dr. Greene is amazing. One of the finest theoretical string theorists in the word today, AND a normal guy who explains it to the rest of us in a way we can understand
Something about waves that eludes me. The very very beginning of a wave. Do you think a wave would originate without mass? What makes a waves form continue to be a wave form as it travels through a vacuum? (Yeah, dark matter everywhere..I know) What is the content of a wave form in a vacuum? I mean, think about it. Wave forms are graphically moving above and below the X axis, as they travel along it. You tell me what the heck causes a particle like light to travel to below an X axis, and then turn around and travel above it and repeat? Simple enough question, no?
I appreciate the greatness this represents in terms of all that is good in humans. In the face of a culture that is trying to get by on thinking positive thoughts and the sole measure of validation is how much money is generated. But I did not hear much about the ongoing purpose and objectives other than upgrading because we can.
At 5:05, Brian Green already falls for a common misception about Mercury's Orbit. Newtonian physics *does not* require the planet's orbits to be perfect ellipses. Instead, it predicts the precession of the Perihelion of Mercury nearly perfectly. Just the *amount* of Mercury's observed precession deviates very slightly from the prediction of Newtonian physics.
Sincere congratulations to this team and all the people behind them that made us make one step forward in our attempt to understand how is the place where we live in.
if they use 4km long wire and pass dc current at constant rate. then use a voltage measuring device for measuring the deflection .will it work? the gravity wave which may stretch the wire in any possible way could cause a change in resistance .right? if it works it will be more more economical >accurate >less noise. just my opinion . sorry if i am wrong.
Ebin S David True, but change in resistance causes change in voltage proportionally such that current still exist in constant rate. Eventually, deflection can be measured well.
Wow, watched the whole thing, it was really really good. I got more out of this than most highly produced science documentaries. Just a lot of good info, and a good story too.
Fat back tv's been bending light since the early 1900's LOL, I don't know what these guys are going on about... Four electro magnetic coils on the neck of the picture tube bends the light any way you want!
Sure they could replicate it with an electromagnet, but not everything is affected by magnetic force. But everything is affected by gravity. He said earlier, that the amount of force is so small in comparison to other forces that we can sense. But the hard part is trying to do that without any data changes from anything other than gravity waves. Be like trying to see the ripples in the water from a pebble while running a trolling motor in the same spot. Not gonna see the tiny ripples. But with enough dampers, it's possible.
Besides predicting gravitational waves, Einstein also said we would never be able to detect them, he didn't think we would ever be able to build a device sensitive enough.
In the very early days of LIGO, I was involved with the design of the end mass and pick-off telescopes used in the interferometer. I also did the mechanical design of the device that calibrated the face accuracy of the 10 centimeter mirrors and the small magnetic bars that kept them from rotating due to the coriolis force. Back then, the purpose of LOGO was not to detect gravitational waves, but to determine if gravitational waves propagated at the speed of light, or whether they were instantaneous. Once the unique signature of the wave was detected, they were was a very short window to notify optical telescopes to look in the coordinates that the two LIGO installations triangulated. If they witnessed a bright spot, they would have verified that the gravitational perturbation had traveled at light speed. If they saw nothing, it would have eliminated this possibility and supported, but not verified that gravity is instantaneous. These "vibrations" would have effected Earth millions of years ago. LIGO has no way of determining whether the sinusoidal signal is a propagated one, like at the speed of light, or one that has arrived instantaneously due to two neutron stars or black holes revolving round each other. Since the time I worked on LIGO, I've never heard of anyone mentioning this purpose. In fact, every illustration I've seen on the internet shows waves going out in spirals moving through space like two basketballs going round each other on the surface of water making waves. Seeing these scientists get giddy over a wave pattern on a computer screen seems anticlimactic to me. Determining that gravity does not propagate at the speed of light is worth some serious giddiness! Supporting the idea that it's instantaneous is astounding! This makes me wonder what certain notables in science and our military is NOT telling us. When I was doing a fit check of the telescopes within the vacuum spheres of the system at Caltech, there were several military personnel there. Since it was a NSF funded project, that was a bit unusual to me. So, with my big mouth, I said, "I know what you guys are doing here, you're making a UFO detector". To my embarrassment, after the entire room went silent for about 5 minutes, the project manager took me aside and warned me, "We don't mention those sorts of things here". So, all the way home, I thought, what if that's what they are actually doing since UFO's are supposedly using gravity to pull the fabric of space into them rather than travel in a linear fashion? So, Brian, give me a call if you read this and want to get my views on what I think about gravity, time and why photons emitted at intervals still produce interference bars. I'm pretty easy to find by my unusual name.
How bizarre, the first person I heard say gravity was a 'wave' was Bob Lazar (while the science community said it was preposterous to view gravity as a 'wave'). Roll on 20 years and we have this ..hmmmmmm ;)
Thanks for your response, it is always fun to think about these things. I will try to explain more clearly what I mean. The crash of two super sized objects being pulled in to each other by gravity should take a longer time than a millisecond or you will bypass the speed of light by far (which is impossible). This should mean, in my mind, that you should be able to measure this effect for many years until it finally disappears :)
It IS a sales pitch to get more MONEY to keep LYING,.I mean the audacity to think that this experiment says they found gravitational waves is just embarrassing,.You would have to do thousands of these experiments to PROVE that they are correct,.They do ONE and ALL just get on board! Just totally laughable
"I mean the audacity to think that this experiment says they found gravitational waves is just embarrassing. You would have to do thousands of these experiments to PROVE that they are correct" Einstein's idea that light bends around bodies of mass was proven with one experiment.
the world science festival that happened the year before this one, had a panel hosted by Brian Green here, and one of the panelists was one of the principle scientists on the Louisiana LIGO team. Brian was giving her crap because her experiment hadn't found anything yet and he said he would have her back on the year they made the discovery. (she predicted less than 5 years) I wonder why she isn't on this panel!?!?
Applying Quantum Physics (Quantum Eraser & Quantum Entanglement) to the realm of Astrophysics, it can be stated that Gravity Waves do not "exist" within any realm of perception... until we LOOK for them. The moment we observe the Universe outside our solar system the "dance" begins. For example, as one Scientist stated, the two merging Black Holes created a Gravity Wave frequency at the exact frequency where the detector is MOST sensitive. In his own words, "What are the chances that nature would engineer a signal right in our sweet spot." Just as Quantum Physics suggests, this historical finding was simply the Universe responding to being OBSERVED-- taking into account what is “anticipated” by the observer-- the moment the machine was re-calibrated and turned on. Quantum Astrophysicist Nergis Mavalvala describes everyone's self-doubt by asking, "Could we have caused this by our own ignorance or by anything from accidents to malpractice?" I propose that Ms Mavalvala, along with everyone involved, brought about this historical achievement by setting all the pieces in place to allow them to OBSERVE the phenomena. As with the double-slit experiment, wave into particle, the act of OBSERVING the phenomena made it happen (materialized it). You initiated a "dance" with an intelligent Universe. There is no greater argument for the funding of Scientific Research & Development, certainly within the realm of Astrophysics and Space Exploration, when we accept that the byproduct of OBSERVING our Universe might very well be that we are CREATING it. In my opinion, this is the essence of Quantum Physics. Therefore, we should never again ask ourselves, "Why are we here?"
One of the most incredible discussions I have ever listened to. We truly are living on a speck of floating, flexible and often undefinable mass in vast and gargantuan sea. If you never believed in the existence of God, on the 100th anniversary of Einstein's theoretical proof, now is the time to recognise the truth. Creation needs to recognise the creator and we just got the message.
Look at what Musk just said right after this info breaks. I can't talk to you about proofs and science because personal experience is the definition, separate from virtual realities. If you want to know, you will know. That is the truth. Go find out who you are.
Is this a joke comment? If not, feel free to provide us good evidence for creation and a creator. Thanks~ Until that happens, though, the claim will continue to be dismissed as wrong if no good evidence is put forth.
It's just as valid as any interpretation of consciousness or quantum behavior at this point. It's not a theory, it's and interpretation of evidence that already exists. It's a philosophical idea. It's also not entirely religious. For example, essentially, intelligent design is no different from the argument that reality is a computer program, or that reality is math. The extreme bias against intelligent design is unwarranted. Also, there is no reason to limit intelligent design to only Christianity. Nearly every spiritual movement in the history of the human species parallels the basic idea.
The host is very annoying. He constantly interrupts to show he knows his physics and pretends he's funny. Just let the guests speak and if you want to talk about the topic just do a program about it and we'll watch it.
what are you talking about.... Do you even know who Brian is...... He is the most amazing host..... if it wasn't for him, these scientist would get lost in their worlds and the audience couldn't follow them as clearly..... Brian just brings them back on track for the sake of majority of non-scientist audience..... Brian Greene is super humble and very knowledgable
Hello Professor Greene, so the light from the reflected beams cancels out and the detector sees nothing. How does this fit in with conservation of energy? Where does the lasers energy go? Many thanks!
This may be a novice and unrelated query, but does the noise-reducing design (the pendulum-like hardware that mitigates the impact of a engine revving, or a tree falling as Shoemaker described) also reduce the impact of plate tectonics and perhaps deeper geological phenomena that could affect the accuracy of the findings?

No, but that would be off the chart, if you talk about earthquakes.

Compact high-energy systems, scalable gravitational-wave-propulsion, and advanced navigational and human integration components are of keen interest for further deep-space exploration and various defense applications. Generous classified research grants to pursue such experimental development in this area are attainable for qualifying proposals at the agency level. Don't worry, you may be contacted for such consulting roles, if demonstrating interest and ready. Watching always.
What where the precautions against people financialy invested in success of this, like scientists with six digits salaries, to fake a confirming result? How hard would it be?
They would simply have to buy the favor of every other person capable of understanding their experiments and reviewing them who would bother to do so. While the scientific community is not very big, there are enough scientists in this field to make it pretty certain that this scenario probably doesn't reflect reality.
Water waves come from a hard object hitting a liquid surface. The liquid moves in waves .. What is the explanation for the causation of gravity waves? And what liquid is moving in waves ? I’m glad they’re called gravity waves and not space-time fabric waves because I don’t believe there is some kind of fabric knitted out there. I also don’t think time is part of a fabric, it’s a relationship of the movement of objects. Although we don’t understand mysterious forces like gravity completely, warped “space-time fabric” just complicates things with a new mystery which is: what is the fabric? It simply replaces invisible force with invisible fabric. The idea that a force of gravity can’t bend light waves, (or solar wind particles, etc.), but a fabric can, that’s a mistake.
Am I the only one that finds humor in the fact that these genius people can figure all this out but Bryan and Rai can't figure out they are drinking out of the same bottle?
I'll never forget when this discovery was made, the professors at my university took my class to the common room and handed out copies of the paper, explaining to us how groundbreaking it was.

Yes, feel those gravitational waves pulling earth towards them! Careful though, they might suck you off the face of the earth! If they are able to reach that far, maybe the next one might be closer and gravitationally pull everything off earth! Scary stuff!

Gravity isn't a constant so we can't say that it's the weakest field in the universe, the more active a planet and is, the stronger it's gravitational field.
@Huawei is a criminal organization. it would be easier but also incorrect. Unfortunately I have the ability to see things for what they are. Measuring what they call gravitational waves here on earth from somewhere far out in space is a very time consuming job! As you should know that waves propagating from a central point increase in diameter the further out the waves travel, so that means that by the time that wave hits earth, it's going to look like a slow rise in signal and the only way to know if anything actually was measured is to collect data for many years and replay the data at a faster speed so that you can see that there was an actual change taking place. Kinda like looking at the temperature variations over the last 100 years on earth. Gravitational waves are measured as a frequency, if you look at the wave propagation from above, the frequency is much higher at the source but as they move outward they stretch and change to a lower frequency... When an AC signal is so large it could easily be seen as a DC signal so basically back here on earth, it could be so huge that it just looks like a slow rise in activity and not the way that the people who measured it as a fast frequency sweep. It almost looks like the signal was fabricated on a frequency sweep generator. I guess that their funding is now secured.. Maybe I know something about physics or maybe I don't but if you just accepted everything that you have been taught and told, then you might as well be religious where your not supposed to question anything. I didn't realize that people had to obtain a PhD to become so stupid, thankfully I missed out on that opportunity.
@Huawei is a criminal organization. Wow! Target! Really! They couldn't afford me and the school's that you attended just weren't good enough for me either. It clearly shows how bad your education is by your remarks. It's not your fault, you thought that by attending those institutions that you will be intelligent enough to put me down but I'm afraid it's not working. I know everything that you know and then some. If you really had any intelligence you would have made an effort to listen when someone else talk's and then you would question why is it that they are thinking what they are thinking, but no! Your the one who read all those books, your the one who attended all those lectures, your the one who holds that piece of paper that claims you know something. Are you but hurt that the most successful and wealthy people in this world are all high school dropouts? How is it possible that people like you armed with your piece of paper can't do better than a high school dropout? What is it that you were not taught in school that's preventing you from being successful at anything? I know what it is, you rest on your piece of paper as if it actually means something, your not the only person who studied so there's hundreds of other people just like you. The thing that you are missing is that one thing that you weren't taught at school, and that's the ability to see that which no one else can see even though it's in plain sight! And it's so easy when you have studied electronic engineering, geology, history and just about every other subject that you care to mention. No one forced me to learn anything because no one had to, it comes naturally to me. I'm so smart that I can give you a real plausible alternate theory on any topic that you could care to mention. I know all current theories and concepts but most of them are incorrect and that means most of what you know is also incorrect too. You make sure that you frame your piece of paper and place it where your uneducated associates can see it because you like them don't really know as much as you think that you know. LoL frequency and magnitude, don't you mean frequency and amplitude, looks like you might want to learn some more about Electronics because you are going to need it. The nerve of some people, the minute someone has a theory that they weren't taught, they label them as uneducated lol when they are the ones that don't know.
@@PeterMilanovski hi there, just to clear up a couple of misconceptions for you, (bearing in mind, I do have a physics education but I'm not an expert on g waves). A brief explanation of Einstein's general relativity describes gravity as the curvature of spacetime due to massive objects. The more massive, the more curved spacetime becomes around the object and other objects (whilst also curving spacetime themselves) follow straight lines but in a curved spacetime around the object, so it looks like their trajectories are curved by it. This leads to notions of orbits as being straight lines but in curved spacetime. If two objects are extremely compact and massive (e.g. black holes or neutron stars) and are mutually orbiting each other, their orbit gradually decays. The closer they get, the faster they spin around each other due to conservation of angular momentum. Eventually they merger together, but just before they do, they are rotating extremely fast around each other. This high speed and large mass lerturbs spacetime in a repeating pattern (a gravitational wave) that propagates put into the universe at the speed of light. While the strength of the wave does gradually dissipate as it travels, the frequency is conserved so it doesn't need to be measured over a long time. Also, with regards to the strength of gravity, we are referring to the gravitational constant which is very weak and this means you need very high masses to feel gravity. For example the electromagnetic repulsion between the tiny electrons in your feel and the floor is enough to overcome the gravity of the entire planet, hence you don't fall through the ground.
Here is a group of people who are in the frontiers of human understanding and knowledge yet remain so humble. Wow! Bravo!! real superstars

Brian Green is an absolute legend. Very well spoken and clear for us laymen
Also Dr. Michio KAKU. I love both of their talks, every one.
Hope there are more WSF events in 2023. Miss the panel discussions.
I translated this video to Brazilian Portuguese, but I don’t see any subtitles available…
People should see this, be aware of the beauty science can achieve. The idea that Einstein almost 100 years ago predicted that we should be able to see this waves, albeit difficult, 1 billion dollars later and a group of a 1.000 working together to make this happen, is outstanding, really remarkable. I used the word ‘beauty’ because this seems to me to be closest you can get to the subjective experience we have when contemplating art, but in this case you don’t need to see or hear anything, just understand and think about it.
Edson Siquara I concur. Beautiful! I love math and physics.
Thank you for your efforts.
The timing of the gravitational waves LIGO detected was beyond phenomenal.

Rai so deserved his 2017 Nobel. And it nicely rewards his decades long commitment to this project.
A Hollywood producer was on a flight sitting next to Cameron Diaz; she was describing this crazy movie she was making, "Being John Malkovich". The producer sheepishly admitted he was financing it. She laughed and laughed. The money guys behind these very expensive experiments should also be congratulated for persevering when the scientist weren't even sure there was anything to find with these tunnels in the middle of nowhere.

This is the longest RUclips video I've watched and felt wanting more. I'm glad there are many breakthroughs that happened recently, Higgs Boson, BEC, and Gravitational Waves. All these can be related. Einstein still continues to fascinate.

Congratulations on the 2017 Nobel Prize. I already watched this presentation last year when it was first published .. it's still informative and entertaining
Always a treat to observe those who are steadfast in the pursuit of knowledge without hype.
The two physicists beside Brian won the Nobel price in physics in 2017, a year after this video was released. The recipients were Rainer Weiss, Barry C. Barish and Kip S. Thorne "for decisive contributions to the LIGO detector and the observation of gravitational waves."
32:49 Brian Greene "We like to sometimes do a little bit of the math" ... what follows is a rapid tour de force of the Einstein equations. Bravo.
This is a huge achievement in the history of science. And yet there are so many people out there who have no idea about this, and if you ask them about LIGO and gravitational waves, they will just look at you with a confused expression. And if you do explain it to them, they will usually just give you a "that's nice, dear" kind of reply.
Brian Greene your linguistic skills are excellent. Not to mention your perfectly clear train of thought and ability to convey it without a pause, hiccup, or stutter are to me truly impressive. You are a cultural gem for your devotion to science and its dissemination. Thank you very much!
Always a treat to observe those who are steadfast in the pursuit of knowledge without hype.

I don't understand Niel Tyson
He is just a audience creep
Physicists are insane. They're so intelligent!
especially the intelligent ones
@@LowKickMT yeah they’re pretty intelligent
They're alright, I guess.
Yes, and reasonable and often very humble.
Awesome time to be in, this discovery is super bad ass.
Not anymore they really just feel jealous now and ask them to do homework nobody has said four eyes since the 50s
Brian Greene, the stand-up comedian of theoretical physics.
Yes, and I want to live his life, though only for a few years...
At 1:04:00 he sounds like Jack Nicholson!
I am not saying he's wrong here, but he needs to understand that experimental Physics is different from Theoretical Physics...methods and results of different experimental means and ways need to be correlated before one can claim a Proof ...without verifying the results of other experiments and depending the inference on only just two findings of the similar experimental setup & means can be a case of False Positive too...
Rajiv B
You're right, he is talking about experimental physics in this video. I guess i was thinking of the first I'd heard of him which was though his book 'The Elegant Universe' ; String Theory or 'M Theory' is definitely more theoretical than experimental.
Holy cow you re a true fool, Rajiv. Sorry
Such brilliant, inspiring, intelligent people, and an absolutely mind blowing discussion! :) I enjoyed every minute of it, thank you.
That we should find ourselves living in such times of Discovery. Amazing.
This is really excellent; the best in the series from the World Science Festival that I have seen.
By the way - Rai Weiss is 83 years old in this video. Amazing shape for that age. Physically and mentally. Respect
I love that the numerical part goes on the longest, speaking for myself personally I never hear enough about the nitty gritty of the math, which lets admit is the language of nature and physics. Also such an interesting look at Einstein’s field equations
So, here's a guy who's devoted his career to string theory and is careful to put a caveat on someone else's implicit assumption that string theory is correct. Where else do you see this? In politics? In religion? That one moment is a little jewel hidden in the rest of this excellent presentation.
He puts caveats on his own hypotheses, string theory being one, of course.
Exactly. Short term, self serving bullshit that doesn't get supported by evidence in the long run doesn't help you and actually hurts you in the long run. Religion and politics is the opposite. Even Einstein, among the greatest scientists ever, made fairly large errors which he openly admitted. That humility is what is so refreshing about science for me too.
That's because it's a hypothesis.
I liked your comment;don't know how many physicists make the mistake of confusing theory with fact; there's a wonderful combative as well as cooperative element to all discussions on the nature of reality which may, however, seduce us into such confusions. For an experimental scientist, this error might seem simply egregious - particularly as no-one's come up with a currently feasible way of testing this elegant & powerful theory. Even if they confirmed it, it would remain falsifiable as this is key to theoretical improvement & in any case a fundamental part of the scientific method. So it's indeed good to hear someone who really likes string theory say 'Well, I really don't know;' come to think of it it's sometimes sold as the only plausible basis for a unified theory. A little premature lol. Politics and religion sigh groan swear.
I see it diferent. I think you would be correct if Greene was the one to came up with the string theory, but was the LIGO dude who did came up with the string stuff predictions.
This was just phenomenal. Truly inspiring to show how human ingenuity and collaboration can help us understand our universe a little bit more.
"with a little bit of massaging" hilarious.
Every molecule all around us is dancing to the beat of our vibration-
Popin and Lockin mostly...
FYI : Rainer Weiss and Barry C. Barish won 2017 nobel prize for the contributions in LIGO and detection of gravitational wave.
HELP: The description educators use to describe space bending via gravitational forces troubles me because we use the analogy of a trampoline and a heavy object in the middle to describe such phenomena. However, the description is taking place in a semi-2D grid and we know, obviously, reality is in 3D. So in all, the waves do not travel just in the x-axis but in a complete 360 degree coverage from the origin. I am probably not making sense, but the trampoline description does not fulfill my mind; I just want to see space bending in a 360 degree coverage but that will not look as appealing as the former analogy. Anyways thanks!
You just blowed my mind as I thought completely the same thing. The same question, the same answer.
Amén hermano
The 2D grid is just a representation since it is very difficult to describe in full 3D, yes, the gravity wave propagates in 3D, if you rotate the 2D grid in 360 degrees both laterally and longitudinally, that would be the true representation, but as I said, this is a difficult view, therefore represented in 2D.
Math, the universal language ;)
Yes, you see, we've simply collapsed one of the 3 ordinary dimensions.
Choose whichever you wish to collapse.
Then try to "uncollapse" it ... envision the curvature of spacetime in 3d, then move to 4.
Hey, think about how the light of a star behind the sun wraps around around our sun before being observed here on earth.
Just bought one of Brians books, this wsf vid has got me even more excited to dig in on it! Great work guys!
Thank you for this video and to brian to simplfy things. Without him you'll easily lost the track and he helps a lot to understand many things discussed.
Why can't we have something like this for prime time TV? No teen drama about getting laid, just some basic or complex science about our universe; on what channel in what part of what world can I find this without commercials? RUclips is the only place I've seen this (with a touch of ad block) but why is this not mainstream programming? Ehh, I digress, have at 'er!
Good stuff, I need more!
I’m always amazed by male or female scientists that kind of appear to know part of how nature works in a very tangible way not just wander around this world to get ends met.
REMARABLE!!! Imagine how grand these people will be thought of a couple of hundred years from now. Thank you all.
Can't believe someone still say that the earth is flat when we (as human) already found gravitational wave.
What are the Flat Earthers going to say now ?
All footballs are flat!
Yeah those flat earthers are pretty crazy
Dude the waves themselves are flat - they fit in to the theory .... lol theyre just a little too flat for us to see lol our 3d eyes make it 3d but its really flat lol
Flat earth = "low" / "down" life.
It's a semblance towards Christain philosophy.

It's very humbling to hear from a Nobel prize winner that he couldn't teach relativity and how difficult it was for him to understand the operational details of the first experiment on gravitational waves. And also how this difficulty led him to come up with a simplier and more precise idea for detecting those waves.
Two things: First, an absolutely fascinating discussion among very intelligent people. Two, Brian Greene is a genius and the best host/moderator of WSF discussions possible. He clarifies complicated issues easily and allows panel members to talk without continually interrupting them.
This is amazing stuff! Thank you for sharing with us. So much fun!
Love to all of you.
Awesome presentation, very much appreciated.
No one dares to make that wave animation 9:00 in real 3D in all directions, always in the plane LOL
All diagrams of Gravitational waves I have ever seen are basically a wavy line but what we dont see or explained is how gravity goes in every direction so instead of a wavy line we would actually see a Wavy Bubble.
I am totally impressed at the human spirit's ability to continue to see awesome things in the mind's eye and continue until it is realized by observation.
You're EASILY impressed ,.
I have been waiting for you guys to put this together haha. Thank you so much for all the knowledge.
Thank you very much to Mr Brian Greene (moderator) to explain what the mathematician nerds have a hard time explaining, by treating the audience with respect.
just wanted to say, I agree, Dr. Greene is amazing. One of the finest theoretical string theorists in the word today, AND a normal guy who explains it to the rest of us in a way we can understand
I dont like him actualy. Too smug for my taste...
MORE!!! please. And thank you.
Something about waves that eludes me. The very very beginning of a wave. Do you think a wave would originate without mass? What makes a waves form continue to be a wave form as it travels through a vacuum? (Yeah, dark matter everywhere..I know) What is the content of a wave form in a vacuum? I mean, think about it. Wave forms are graphically moving above and below the X axis, as they travel along it. You tell me what the heck causes a particle like light to travel to below an X axis, and then turn around and travel above it and repeat? Simple enough question, no?
Now you are getting it. The slit experiment should explain this to you.
I love how humble and cautious that are being
I appreciate the greatness this represents in terms of all that is good in humans. In the face of a culture that is trying to get by on thinking positive thoughts and the sole measure of validation is how much money is generated. But I did not hear much about the ongoing purpose and objectives other than upgrading because we can.
so, when will the documentary come out?
Yes I asked the same thing. Finally something new.
Is einstein the most intelligent human being that has ever lived?
That would be me, but Einstein is a close second.
When asked what it was like to know genius, Einstein replied, "I don't know, you will have to ask Tesla."
I'm sorry to inform you that you are a 'close second."..after...well..me. ;-)
At 5:05, Brian Green already falls for a common misception about Mercury's Orbit. Newtonian physics *does not* require the planet's orbits to be perfect ellipses. Instead, it predicts the precession of the Perihelion of Mercury nearly perfectly. Just the *amount* of Mercury's observed precession deviates very slightly from the prediction of Newtonian physics.

Gravity waves , the dance of the dead in their graves .....dancing waves forever .
Watching in 2019 and nothing has changed
And many think that basic research is a waste, but it yields our lives in the future. Sticking to old worn-out ideas then is dangerous!
if they use 4km long wire and pass dc current at constant rate. then use a voltage measuring device for measuring the deflection .will it work? the gravity wave which may stretch the wire in any possible way could cause a change in resistance .right? if it works it will be more more economical >accurate >less noise. just my opinion . sorry if i am wrong.
Ebin S David True, but change in resistance causes change in voltage proportionally such that current still exist in constant rate. Eventually, deflection can be measured well.
This was really inspiring to hear the back-stories and the process.
The turtles love waves.
the best part of these videos? The comment section! the enthusiasm is awesome.
Good thing we got that built in time to detect it. I can't imagine if we had missed it. Life would be over.
They've found quite a few more since then.
Great presentation! Loved it!
Wow, watched the whole thing, it was really really good. I got more out of this than most highly produced science documentaries. Just a lot of good info, and a good story too.
So gravitational influences can vary from a phenomenon that is essentially a "Cosmic Quake" ??
if gravity bends the imaginary space/time fabric then what is magnetism bending to cause attraction ?
Fat back tv's been bending light since the early 1900's LOL, I don't know what these guys are going on about... Four electro magnetic coils on the neck of the picture tube bends the light any way you want!
Sure they could replicate it with an electromagnet, but not everything is affected by magnetic force. But everything is affected by gravity. He said earlier, that the amount of force is so small in comparison to other forces that we can sense. But the hard part is trying to do that without any data changes from anything other than gravity waves. Be like trying to see the ripples in the water from a pebble while running a trolling motor in the same spot. Not gonna see the tiny ripples. But with enough dampers, it's possible.
Stunning presentation and lecture. There is no limit to human imagination.
Besides predicting gravitational waves, Einstein also said we would never be able to detect them, he didn't think we would ever be able to build a device sensitive enough.
How I just love when string theorists blurt out that stuff without any proof or prediction.
Can't believe someone still say that the earth is flat when we (as human) already found gravitational wave.
If your surnames Barish you dont call your son Barry!
I went to school with a kid called Marcus Farkus, I kid you not.
In the very early days of LIGO, I was involved with the design of the end mass and pick-off telescopes used in the interferometer. I also did the mechanical design of the device that calibrated the face accuracy of the 10 centimeter mirrors and the small magnetic bars that kept them from rotating due to the coriolis force.
Back then, the purpose of LOGO was not to detect gravitational waves, but to determine if gravitational waves propagated at the speed of light, or whether they were instantaneous.
Once the unique signature of the wave was detected, they were was a very short window to notify optical telescopes to look in the coordinates that the two LIGO installations triangulated. If they witnessed a bright spot, they would have verified that the gravitational perturbation had traveled at light speed. If they saw nothing, it would have eliminated this possibility and supported, but not verified that gravity is instantaneous. These "vibrations" would have effected Earth millions of years ago.
LIGO has no way of determining whether the sinusoidal signal is a propagated one, like at the speed of light, or one that has arrived instantaneously due to two neutron stars or black holes revolving round each other.
Since the time I worked on LIGO, I've never heard of anyone mentioning this purpose. In fact, every illustration I've seen on the internet shows waves going out in spirals moving through space like two basketballs going round each other on the surface of water making waves. Seeing these scientists get giddy over a wave pattern on a computer screen seems anticlimactic to me. Determining that gravity does not propagate at the speed of light is worth some serious giddiness! Supporting the idea that it's instantaneous is astounding!
This makes me wonder what certain notables in science and our military is NOT telling us.
When I was doing a fit check of the telescopes within the vacuum spheres of the system at Caltech, there were several military personnel there. Since it was a NSF funded project, that was a bit unusual to me. So, with my big mouth, I said, "I know what you guys are doing here, you're making a UFO detector". To my embarrassment, after the entire room went silent for about 5 minutes, the project manager took me aside and warned me, "We don't mention those sorts of things here".
So, all the way home, I thought, what if that's what they are actually doing since UFO's are supposedly using gravity to pull the fabric of space into them rather than travel in a linear fashion?
So, Brian, give me a call if you read this and want to get my views on what I think about gravity, time and why photons emitted at intervals still produce interference bars. I'm pretty easy to find by my unusual name.
Why is it that physics and mathematics seems to attract kooks? Let me guess. You also have a solution to the Riemann conjecture too, I am sure. 😂
Plot twist: the technician fixing the system actually did an injection but forgot to log it... Then was too embarrass to mention it at all.
How bizarre, the first person I heard say gravity was a 'wave' was Bob Lazar (while the science community said it was preposterous to view gravity as a 'wave'). Roll on 20 years and we have this ..hmmmmmm ;)
How can 2 huge black holes crash in a second and then go back to normal? It should be happening for a looooong long time right
Thanks for your response, it is always fun to think about these things. I will try to explain more clearly what I mean.
The crash of two super sized objects being pulled in to each other by gravity should take a longer time than a millisecond or you will bypass the speed of light by far (which is impossible). This should mean, in my mind, that you should be able to measure this effect for many years until it finally disappears :)
Yes but imagine the time it would take for two black holes to crash, it should take many years to complete the crash
Yea but you see my point? It is very strange to me
A ok yes I did not get that from the interview... :) "In a split of a second"
Funny , a slow merger sounds strange to me, when you have such masses beside each other, the gravity gets infinite.
This dude sounds too much like he's giving us a sales pitch....
It IS a sales pitch to get more MONEY to keep LYING,.I mean the audacity to think that this experiment says they found gravitational waves is just embarrassing,.You would have to do thousands of these experiments to PROVE that they are correct,.They do ONE and ALL just get on board! Just totally laughable
"I mean the audacity to think that this experiment says they found gravitational waves is just embarrassing. You would have to do thousands of these experiments to PROVE that they are correct"
Einstein's idea that light bends around bodies of mass was proven with one experiment.
great to see a Pakistani scientist.
@EIRE LAND that's a little rude
I got about 1 hour 10 minutes into this and wonder what kind of effect gravitation waves have on the GPS system.
the world science festival that happened the year before this one, had a panel hosted by Brian Green here, and one of the panelists was one of the principle scientists on the Louisiana LIGO team. Brian was giving her crap because her experiment hadn't found anything yet and he said he would have her back on the year they made the discovery. (she predicted less than 5 years) I wonder why she isn't on this panel!?!?
Gravity, strong enough to keep the oceans stuck to the earth but weak enough to let little bugs fly around. It's magic!
Gravity is love
Because the mass of the oceans is so much more than the mass of all the bugs. You see it?
Justin Alexander:It is strange that you don't believe NASA, but you believe folklore.
Justin Alexander Well, bugs have can fly, so...
Ever seen a dead bug defy gravity?
yes, my mother
The must be a multiverse because socialism has to work *somewhere*

Applying Quantum Physics (Quantum Eraser & Quantum Entanglement) to the realm of Astrophysics, it can be stated that Gravity Waves do not "exist" within any realm of perception... until we LOOK for them.
The moment we observe the Universe outside our solar system the "dance" begins. For example, as one Scientist stated, the two merging Black Holes created a Gravity Wave frequency at the exact frequency where the detector is MOST sensitive. In his own words, "What are the chances that nature would engineer a signal right in our sweet spot." Just as Quantum Physics suggests, this historical finding was simply the Universe responding to being OBSERVED-- taking into account what is “anticipated” by the observer-- the moment the machine was re-calibrated and turned on.
Quantum Astrophysicist Nergis Mavalvala describes everyone's self-doubt by asking, "Could we have caused this by our own ignorance or by anything from accidents to malpractice?" I propose that Ms Mavalvala, along with everyone involved, brought about this historical achievement by setting all the pieces in place to allow them to OBSERVE the phenomena. As with the double-slit experiment, wave into particle, the act of OBSERVING the phenomena made it happen (materialized it). You initiated a "dance" with an intelligent Universe.
There is no greater argument for the funding of Scientific Research & Development, certainly within the realm of Astrophysics and Space Exploration, when we accept that the byproduct of OBSERVING our Universe might very well be that we are CREATING it. In my opinion, this is the essence of Quantum Physics. Therefore, we should never again ask ourselves, "Why are we here?"
you got it my friend ...... if you only knew how Devine you are
One of the most incredible discussions I have ever listened to.
We truly are living on a speck of floating, flexible and often undefinable mass in vast and gargantuan sea.
If you never believed in the existence of God, on the 100th anniversary of Einstein's theoretical proof, now is the time to recognise the truth.
Creation needs to recognise the creator and we just got the message.
Creation is the creator how could you possibly separate the two
Adam Zillin
Look at what Musk just said right after this info breaks.
I can't talk to you about proofs and science because personal experience is the definition, separate from virtual realities.
If you want to know, you will know.
That is the truth.
Go find out who you are.
Is this a joke comment? If not, feel free to provide us good evidence for creation and a creator. Thanks~
Until that happens, though, the claim will continue to be dismissed as wrong if no good evidence is put forth.
It's just as valid as any interpretation of consciousness or quantum behavior at this point. It's not a theory, it's and interpretation of evidence that already exists. It's a philosophical idea.
It's also not entirely religious. For example, essentially, intelligent design is no different from the argument that reality is a computer program, or that reality is math.
The extreme bias against intelligent design is unwarranted. Also, there is no reason to limit intelligent design to only Christianity. Nearly every spiritual movement in the history of the human species parallels the basic idea.
When my fat cousin walks, h makes the floor shake. Are these also gravitational waves?
I thiink they detected your cousin lol
If you were gravitating towards him then yes.
The host is very annoying. He constantly interrupts to show he knows his physics and pretends he's funny. Just let the guests speak and if you want to talk about the topic just do a program about it and we'll watch it.
I like Brian Greene but i agree he was showing off. He appears on the TV channel NOVA in a lot of documentaries.
Brian's great, he is interrupting to clarify what is being said for the audience. I kinda see what you mean tho.
what are you talking about.... Do you even know who Brian is...... He is the most amazing host..... if it wasn't for him, these scientist would get lost in their worlds and the audience couldn't follow them as clearly..... Brian just brings them back on track for the sake of majority of non-scientist audience..... Brian Greene is super humble and very knowledgable
Hello Professor Greene, so the light from the reflected beams cancels out and the detector sees nothing. How does this fit in with conservation of energy? Where does the lasers energy go? Many thanks!
This may be a novice and unrelated query, but does the noise-reducing design (the pendulum-like hardware that mitigates the impact of a engine revving, or a tree falling as Shoemaker described) also reduce the impact of plate tectonics and perhaps deeper geological phenomena that could affect the accuracy of the findings?
No, but that would be off the chart, if you talk about earthquakes.
Dr. nargis is of pakistani origin. so proud of her.
so proud, but SJW's would likely point out the lack of male color diversity
And so? where is connection between gravity and other forces? bla bla bla
+Kassyni, Eating shit is the answer?
quality convo, guys.

This man has never been bowling.
Compact high-energy systems, scalable gravitational-wave-propulsion, and advanced navigational and human integration components are of keen interest for further deep-space exploration and various defense applications.
Generous classified research grants to pursue such experimental development in this area are attainable for qualifying proposals at the agency level. Don't worry, you may be contacted for such consulting roles, if demonstrating interest and ready. Watching always.
What where the precautions against people financialy invested in success of this, like scientists with six digits salaries, to fake a confirming result? How hard would it be?
They would simply have to buy the favor of every other person capable of understanding their experiments and reviewing them who would bother to do so. While the scientific community is not very big, there are enough scientists in this field to make it pretty certain that this scenario probably doesn't reflect reality.
Water waves come from a hard object hitting a liquid surface. The liquid moves in waves .. What is the explanation for the causation of gravity waves? And what liquid is moving in waves ? I’m glad they’re called gravity waves and not space-time fabric waves because I don’t believe there is some kind of fabric knitted out there. I also don’t think time is part of a fabric, it’s a relationship of the movement of objects. Although we don’t understand mysterious forces like gravity completely, warped “space-time fabric” just complicates things with a new mystery which is: what is the fabric? It simply replaces invisible force with invisible fabric.
The idea that a force of gravity can’t bend light waves, (or solar wind particles, etc.), but a fabric can, that’s a mistake.
Am I the only one that finds humor in the fact that these genius people can figure all this out but Bryan and Rai can't figure out they are drinking out of the same bottle?
