he won the Nobel prize. Gravitational waves in linearized gravity can be described as manifestly observable Riemann curvature tensors from Einstein's field equations. The Ricci tensor will vanish while the Riemann tensor can be nonzero as well. The components of the affine connection (Christoffel coefficients) can be given by partial differentiation. The usual notion of 'gravitational force' disappears in general relativity, replaced instead by the idea that freely falling bodies follow geodesics in spacetime. Given a spacetime metric gab and a set of spacetime coordinates xa, geodesic trajectories are given by the equation as where τ is a proper time as measured by an observer travelling along the geodesic.

I searched so long for a good detailed and scientific explanation of gravitational waves and finally found it. Thank you, Mr. Weiss for the insightful talk!
Amazing, there should have been a detail introduction of the speaker and how much he contributed to science and our understanding of the world we live in
i don't understand what the frequency is. is it the frequency of the gravitational wave oscillation right, the energy? the sound thing is just for visualization i would assume?
How do the gravitational waves actually affect the apparatus? 1) locally change the speed of light 2) make the mirrors actually move in relation to each other 3) locally make space grow and shrink 4) make time run locally faster and slower 5) some combination thereof?
I'll try to explain as much as i know. 1)it stays the same, light does not need a medium to travel and there exists a vacuum inside 2)They stay at the same place, 40kg mirrors(really thick) 3)exactly, so light travels more and less distance accordingly 4)no this doesn't happen Basically it's just time = (distance/speed), due to the expansion and contraction the distance changes, so does the time and subsequently the phase difference between the light waves(lasers). So when they interfere, they don't cancel each other and this difference in the final result is what is seen.
People do a lot of visualization about the physical evidence of several of these theoretical constructs. Flatland ( a fictional novella) has been used for the same purpose to visualize higher dimensional objects. But the truth is, once we acquire the physical evidence of such a nature, people need to understand it's real characteristics. And that's what gravitational waves are: the physical evidence of the general theory of relativity.
re 2:30 Isn't the lattice a constant time surface? The clocks on that surface would stay synchronized, and clocks closer to the objects would go slower, and clocks very near a BH would appear to be frozen. . Perhaps it is obvious, but isn't gravity an effect of time-space distortion by mass, rather than a force, just as "centrifugal force" and "Coriolis force" are effects of situations rather than like the strong, weak, and EM forces? (I might reasonably extrapolate that at some time we would resolve the last three to effects also. ... which begs the question, 'What is a force?")
Cant you understand the distortion of spacetime as local variations of speed of light in undistorted spacetime? Like index of refraction? Put some sugar and water into a glass, you have variable index of refraction, light travels in curvy paths, voila, a desktop general relativity. Maybe its even anisotropic, like birefrigent crystal. Maybe the gravity just slows down the light around?
@@aidancanoli Check out "Search for Frame-Dragging-Like Signals Close to Spinning Superconductors" Apparently this was a legitimate study. . . Very strange. They claim that frame dragging effects are greatly amplified around superconductors. Basically, that a rotating object (like the earth) will show a difference on a clock depending on whether it is traveling around with, or against, the direction of rotation, but the effect is massively more pronounced in the vicinity of a rotating superconductor.
Its measured as a tensor, the dots he showed about half way through is a very simplified visualization of what a tensor does. Tensors are essentially matrices that are vectors on each point on a plane.
i think you would just create a unit length though for the ricci curavture which is part of Guv and then the Guv ends up being 1/length^2 so i think u can use meters. or anything u want. i don't really have any idea just from what i saw on wikipedia that seems to be a case. but i do know its not really as much a value as it is a description of the geodesic geometry that we can comprehend to describe particles affected by spacetime and how particles effect spacetime. we don't necessarily need to know the exact units, rather define points and their spacing to see the final outcome, the resulting einstein field.
Big Respect … It is unbelievable how far we humans made it. Science can be so exciting, but unfortunately not all of us has access to these informations. Great Stuff and great Person with a lot of Humor ✌️👍😎
Different gravity-mass rotation = different gravity frequencies. Different gravity frequencies. = different gravity waves. # Gravity's influence is proportional to the masses of the object involved. But gravitational waves distort space only by a factor of 10^20. That means if there is a cosmic mass-gravity object 10^20 millimeters size (ten light years), a gravitation wave would distort space on one millimeter. Not more. # Gravity is the weakest phenomena in the Universe. Gravity is about 10^36 (10^41) times weaker than EM phenomena. # Therefore gravity-waves cannot be measured by any tools. To understand macro-gravity effect, needs to understand quantum-gravity. ===
this is so advance stuff for me. I cant even find anything where and what he wants to see but then again I don't even understand equation of Einstein at all.
Can you take a fresh look at the universe? PATENT 33869 An experiment is proposed, which is not difficult to understand, on the creation and study of super-powerful gravitational waves or the inconstancy of the speed of light in a vacuum. The choice is yours.
In this video, Rainer Weiss tells the whole world he doesn't understand Einstein at all ! ^^ Einstein came up with the Space-Time Curvature theory because it was objected to him that "gravitational waves" were too slow to explain Gravity. Indeed, Gravity is observably instantaneous and thus "waves" (which are limited to the speed of light) cannot explain observable reality !!! Finding an explanation for instantaneous Gravity is precisely what made Einstein a famous genius. The concept of Einstein's Space-Time curvature literally cancels the need for slow "gravitational waves" ... Science is going backward ! :(
Of all my research about LIGO and gravitational waves, it has a feeling of junk science and confirmation bias. Someone explain to me why gravitational waves and the electromagnetic spectrum should travel together.
Maybe the masses wiggle in space maybe light just travels faster horizontally and slower vertically. So you meaure the distance with laser and think the masses wiggled. According to Occam's razor the explanation with speed of light is better because it involves only 1 thing to change. While his explantion inolves a hundred of test masses to wiggle.
If they eventually detect every gravitation wave possible, what is the payback in terms of making everyone's life better on Earth after all the time, effort, and money spent?
Maybe we can’t understand the implications now. But someday we will. Maybe someday understanding these gravitational waves will help us open portals to the universe (just a metaphor)
@@tanimmahfuz8689 they indeed open portals to the universe, if we are able to acces the gravitational wave and amplify it.. just like any other wave. Considering that we are able to bend space and time with a strong gravitational field... we could actually travel vast distances in space in little to no time. Us humans think of travel in linear motion as the only way possible to get from point A to point B which is pure Rubbish
Disappointed he did not discuss the nature of 3 solar worth of non photonic mass carried away by the GW at light speed. What do you call that kind of mass? Dark matter? Actually no one wants to discuss this question. Why?
Lol on that time scale it's surprisingly simultaneous. Light is always a bit slower than c since space isn't a perfect vacuum. The medium slows it down. The fact that the delay is so minute shows their was an exceptionally empty space it traveled through.
well if gravitational waves travel truly uninterrupted, then makes sense over such a long distance there would be a delay and you would hope to see light slightly later. there's gas and other materials that have different refractive indices and can interact with light and slow it down. there was also probably a slight path difference too which probably doesn't affect it much. its surprising its so close actually considering how many things could get in the way.
Truth number One: Einstein was right. There exist Gravitation and thus their waves. Truth number two: They travel not at (expected) speed of c but at much higher CxC = c2 speed. you can not even detect from which direction they are coming because they are that fast for this time domain. Truth Number three: Yes, It is possible to build a transmitter/receiver pair to use gravitation as transport medium for very long distances like between star systems. To communicate with another galaxy even speed of gravitational waves are not enough. To succeed this, one need to put a receiver/transmitter pair in front of a stargate which is opening to another galaxy of interest. Same person must know the transport protocol and thus must use the same. Therfore there must exist at least one common transport protocol already created for that purpose.
That's nonsense already for the following reason: c*c isn't speed. Unit of speed is meter per second (or kilometer per hour, or the like). If speed of gravity were numerically equal to c*c, in what unit is it? Kilometer per second (300 000 times the speed of light)? Meter per second (300 000 000 times the speed of light)? Kilometer per hour (1 000 000 000 times the speed of light)? And how did you conclude that speed of gravitational waves were significantly faster than the speed of light? General relativity predicts that it's the same as the speed of light, and no information can propagate faster (this speed also being known as the speed of causality). And observations are consistent with this prediction. And we certainly were able to detect the direction where the gravitational wave has come from (detecting the wave at measurably different moments by different detectors). On occasion, we were able to connect the gravitational wave with an actual astronomical observation (a gamma ray burst and visible light from a 'kilonova' event - brighter than a nova but less bright than a supernova - from a neutron star collision). And communication by gravitational waves - gee, good luck at that. Technically, whenever a mass moves with acceleration in a gravitational field, this produces gravitational waves; but these waves are way too weak to be detectable. And stargates are science fiction, not something that actually exists.
MikeRosoftJH lets make a deal: We meet and I build you a phonon Emission transformer. With that device you obtain power out of exactly “nothing”. Soon you see this you gonna believe everything I tell you. Okay? Deal?
Do human beings see everything that is capable of happening as we are able to understand? Why shouldn't there be more. Are the human senses completely capable of detecting every single facet of the universe? There has to be more ways to sense things that occur not to our human knowledge that are just as fundamental as sight is to us. There has to be more fundamental sense that see the universe in completely different ways just as audio is entirely separate from visual. What could possibly be another sense to witness by?

Existence of gravitational waves can be proven even from Newton law. We have a falling stone 1kg, a=9.81 m/s. F=ma=9.81. Now we know gravity is not a force, just a deformation of spaceime, so F=0. 9.81=0. We have a contradiction. Now, anything follows out of a contradiction.
