Einstein Was Right: Gravitational Waves 101 | Rainer Weiss | TEDxNatick

[themule]

I think that this talk does a pretty good job of showing that a lot of math and science is perspective, not simply prescriptive. It's humbling.

[umbertopappalardi]

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!

Gravitatinal waves! What a great time to be alive. I hope to be able to live long enough to see a proper model of gravitational waves in form of particles or something like that.

[raghav]

The passion with which he explains the discovery is infectious!

[TengouX]

Love how this guy calmly states that modern day GPS technology is more subtle and precise than the technology that got a man to the moon.

[Rico-Suave_]

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

[julianstaniewski]

Well why does this only have so many views?
It is a great in depth explication, well done

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?")

[mxrkxo]

He is really delightful in explanation

[aidancanoli]

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?

[AustralianGQ]

Great talk on gravitational waves. very exciting stuff.

[merrysfuneral]

My brain exploded. I am a mechanical engineer and it was too much for now. Now I have to digest all the info for the gravitation.

[guersomfalcon]

0:40 How can you solve an equation if all of its elements are variables?

[akumar]

How beautiful the human mind is, uplifting wonderous unique ♥

[charlieangkor]

so the Guv (geometry of spacetime) is measured in what SI units? lumens? meters? amps per cubic volt? ohms per square second?

[charlieangkor]

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?

[sayan]

I wish Albert was there and explaining his theories.

[dboydboy]

So where are these speeches hosted at? Ive been trying to attend one for years...

[SJ-todt]

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.

[frodobaggins]

Seeing this you think "how did Einstein even know all this"?
