Man. This makes me want to pick up a paper and start researching again!

Wait. That's precisely what my adviser wants me to do...

It’s fascinating that Albert Einstein predicted gravitational waves in 1918 and it took almost a century, 2016, to prove him right.

[haghalam]

gravitational FUCKING waves confirmed, I love that

[wokewoc]

The answer is YES THEY HAVE BEEN DISCOVERED!
i am just so excited i dont understand this very well but i love this, Gravitulations everyone !

[afridrasul]

Love 💕 the way of Einstein’s prediction of gravitational waves from general theory of relativity !! to 20th century LIGO experimental gravitational waves detection

It’s actually a dream come true for Einstein 🤘🏼🤘🏼🤘🏼🤘🏼🤘🏼

Another great video from PHD Comics! I have thoroughly enjoyed this. I hope there's more physics research videos soon.

WHAT U HAVE TO SAY BOUT THIS, JESUS??

There is so much about the universe that we don't know and there will be much we would not be able to know ever. The video proves how limited human mind is to understand the vagaries of this utterly complex universe. The fact that we are in awe with the detection of anything new, shows how little we know about the universe as yet and how much more we are to discover in future. This is why we should be humble enough to accept our limits and be skeptical of even the science, not just religion(which is obviously for the sheeples) and spirituality. To know that you don't know is the best thing you could know.

Great animation. Really fluid and to the point.

Very nice and interesting, the italian subtitles are perfects also. Good job man :)

[talibanshill.]

awesome video...great effort made to make such a clumsy topic simplified..

[bishoz]

Thank you. I had a vague-ish idea - now I have a slightly less vague-ish idea. But I did learn something!

[MrRenoo]

I still don't know how this is going to help us know the universe better

[yannhugo]

Next month, views will have exploded in an exponentiel way!
Congrats to the LIGO's team, and thank you for this nice video, very usefull :)
And by the way, Bruce Allen from the Max Planck Institute for Gravitational Physics in Hannover said, when he first saw the recording, he said "Oh! It's an injection, obviously!" haha!

So wait doesn't the light travel in space-time? why doesn't it get stretched and compressed as other things that are part of space time?

[DecaixX]

This channel explain things better than Ted Ed

But both are bice channels! Thank you for subtitles! Im from Argentina

[bisconect]

Thank your for the intuitive graphical explanation!

[lazeppelini]

so studying space is basically studying stone in the jelly :P

[douglashagan]

The distortion ripple effect is off by two degrees need to read adjust the disc from the rotor in order to centralize the ripple effect in the fabric of the universe this enables me to get through the dark matterhole which gets me into about 50 parsecs into the next galaxy

"There's not an actual force pulling the planets around [an orbit], just a bending of space."

Um...
