How Big Is The Universe?

Is the Universe infinite? Or does it somehow fold in on itself? And if so in what shape? Join us today as explore the size of the Universe. Written and presented by Prof David Kipping, with special thanks to cosmologist Prof Colin Hill for fact checking.

THANKS FOR WATCHING!!

[GameTime-yjqv]

This is the best channel in the observable YouTube.

[fuffoon]

Its remarkable how this question weighs in my mind yet has no real bearing on my life whatsoever. I shouldn't let this make me forget to brush me teeth.

[nateking]

Every time I finish one of these I feel like a changed person. Thank you really for making these and keep up the great work Dr. Kipping.

[artdonovandesign]

I can PROMISE you, Prof. Kipping, that your own impact on _this_ world through your videos is far greater and more positive than anything you could imagine.

[jeschinstad]

Sometimes, when I watch these videos and they end, I feel like I'm coming back to Earth from a trip to space. :)

[tempist]

"Even the smallest acts of kindness can carry infinite weight..." Such a revelation after hearing all the potentially infinite suffering, potential infinite happiness also co-exists. What a truly mind boggling life, how fortunate we are to be able to ponder and explore such things.

[frankr]

My father recently past away and never gave me the time of the day. I made numerous vain attempts to be his son but it wasn’t possible. Because of messages like the one at the end, I made a conscious decision, a resolution to recast my whole life many years ago into the man I though I couldn’t be and I am at peace with the results. Father, my greatest hope is that in another life, another universe, you are my father and me your son .

[beergnomedc]

Easily the best piece of science communication I’ve ever seen. I used to be an entertainment science communicator as well at one point, primarily focusing on astrophysics and astronomy, and this is easily the best I’ve ever seen. The way you broke down and explained some of the most difficult concepts out there is nothing short of amazing.

[TheOkieLife]

Anyone else watch it 3 times?

There's so much knowledge in Cool Worlds videos I often find myself having to watch them multiple times to make SURE I understood it.

Journey to the End of the Universe was the first video I ever watched of Cool Worlds a couple years ago... still amazing!

Best space education channel on YT!

[AUKronos]

The last 3 minutes of this video brought me to tears

These are the kinds of videos I truly appreciate on youtube

Educational, thought provoking and emotional

[iamaskater]

"For example if your mission is to reduce suffering amongst humanity, it is challenged by the fact that in an infinite universe there is infinite human suffering" - yes, but that also means there could be infinite good. Keep pushing.

[abhinandanmalhotra]

The most quality Astrophysics videos ever with so much depth and intellect..! Thanks, Dr. Kipping and Prof Colin for such out-of-the-world content...!

[pepsisock]

I am simply at a loss for words. Probably the best video on this platform. Thank you for the hard work and always inspiring me with wonder.

[Cronites]

Simply some of the best science communication I've ever seen. Bravo and thank you for all of the hard work that goes into each of your videos. ❤

[igortumbas]

Mate, once again you have absolutely blown my mind. I’m still working through the relationship between pure science and meaning. Somewhere I’ve seen a theologian speak of science and philosophy as a complimentary set of concepts. You have brought these 2 so brilliantly in this video. Your emphasis on kindness and compassion oin your closing remarks were really inspiring and resonated with the way I feel about the world. Keep up the good work!

[ghislainedidntkillherself]

I have long been a fan of science channels on youtube, but only recently found yours. I can honestly say this is the first time the true depth of the complete absurdity of different infinities hit so hard. I actually kind of get it now, the stories of philosophers and mathematicians being terrified of the idea of infinity and going insane from the obsession of over it. not that crazy after all

[StreamChill]

The last few minutes was a deluge of feels that I was not ready for. So profoundly beautiful. I hope somewhere, in another universe, they managed to revive my father and he could have grown old and met his grandchildren.

[r.w.]

I've never felt so touched and at the same time uncomfortable. The las part of this video is a true masterpiece and this is the type of content all of us should appreciate. Thank you so much.

[eyeballtickler]

Explained far better and more interestingly than 99% of similar videos out there. Bravo sir 👏

[SM-wlko]

28.55 sums it perfectly, accept defeat in trying to understand everything and make the most of the life you have in this world, which is temporary
