Relativity 12a - gravitational waves I

On September 14, 2015 at 09:51 UTC, the Laser Interferometer Gravitational-wave Observatory (LIGO) made the first-ever detection of gravitational waves. These had been predicted by Einstein 100 years ago. In this video we examine how General Relativity predicts gravitational waves, what they are, and how they can be detected.

That point charge illustration at the end blew my mind, I never seen electromagnetic waves explained like this :)

some amazing videos you are putting out... so happy I found this channel and I cannot wait to binge all of these within the next week of this dreadful quarantine (although it presents the perfect opportunity to learn!!!)

I have to be honest, I get really excited to see you posting a video.

great work, absorbed every second of it!

Thanks i always enjoy these videos. Nice to learn.

8:14 Something seems wrong with these formulas. U is defined as a function of x. What is the derivative with respect to r? If we differentiate U with respect to x, we get infinite force for a ground that approaches a vertical slope, which is certainly not what we want.

Which program did u used for the animations in this video?

Hey man, a bit offf topic but does the old channel still exist? I was looking for your "WLC Cookie Einstein" video but couldn't find it. Cheers and happy holidays
