Man, there's a lot of bad in the world today, no doubt, but the idea that I can sit here and learn stuff like this FOR FREE and as...basically just a relaxing hobby...it's incredible. Each of us can educate ourselves on nearly any topic whenever and wherever we want.

Thank you so much for this. And of course your narration, scripting, production...it's all absolutely top notch. Thank you, thank you.

The voice of the narrator and the way he modulates it are both so important! They can make a difference in whether you are going to enjoy or lose interest in watching. I appreciate the way you speak and pause to highlight certain words; it is part of what makes these videos so inspirational! Thank you for this new content; I cannot get enough of it!

Seen everything on TV since the 70'es but I dont remember having seen anything of the same unique high quality as this series - simply well done!

[srinathradhakrishnan]

I always loved the concept of space time, multiverses and parallel worlds. It's darn fascinating.

[warpdrive]

Can't believe I get to watch such high quality documentaries for free! Much love from India :)

[noahmclaughlin]

As terrifying as it is, I find some comfort in knowing how small we are compared to space and time. It’s nice knowing we aren’t just the center of things

[bestoboth]

As a scientist, by training, I have to say that I have been TRULY impressed by your videos! Your writers are incredibly good at condensing, already incredibly DENSE information, without seeming to lose the actual meaning behind it...🤔

Your video quality is amazing and all of your artists and editors deserve awards!

I am quite eager to see what is in store! 🤓

Edited to give credit where credit is due.

My grandfather who passed away around a year ago actually was one of the people who helped build the Hubble space telescope he was a professor at the University of Caltech I just wish she got more credibility for the things he did and contributed to.

Where did this channel come from and how am I getting a documentary series I'd pay good money for for free?! Thank you, sir. You are a gift to the whole community of aspiring arm chair cosmologists

[victorfreij]

This must be the best video you guys and gals have ever produced. Simply a marvelous explanation of the entire pathway taken to come to this cosmological point of understanding. Well done!!!

[kimyoungjin]

👏 for the cameraman who went to multiverse n the edge of universes to show us this amazing video lol

[conjurors-prelude]

I've watched this three times now and every single time it's like the first time. It's absolutely beautiful and inspiring.

The universe and the atom have much in common. Imagine living on a quark in an atom wondering if there are other atoms made of quarks, and other unknown smaller particles, but not being able to see far enough to know.

[kieranhosty]

This video has more content that many actual documentaries and is an obvious labour of love.
I was absolutely right to subscribe to this channel. Well done on this incredible creation.
(people seem to think I'm gullible or something, no.
I applaud the work that went into collating all these different theories and presenting them in a single work which still manages to be very watchable. We still have plenty of physics left to uncover.)

[abnormTrueCrime]

I wonder how many people are involved in this channel's production. Insane quality research, writing, editing and voiceover!

[suzannebrown]

I really enjoyed hearing about the experiments and theories of our entire existence! It’s mind boggling to ponder. Well narrated too.

[joho]

This is easily the best documentary on the subject I've ever watched, and I've probably watched them all. Being old enough to have witnessed the discovery of the CMB, Dark Matter, Dark Energy, the discovery of most of the "zoo" particles and the birth of supersymmetry and M-theory, it's incredibly rare to find an explanation that weaves these complex subjects together so succinctly. This explores the history of modern cosmology very nicely and brings our current understanding of the universe and the "Theory of Everything" into clear focus. I especially enjoyed the exhibits shown, such as Hubble's handwritten research on Cepheids in M31. Really phenomenal work here.

[ivnx]

I thank youtube everyday for allowing the existence of channels like this, thank you guys for putting out another incredible masterpiece of a video, I loved it!

[MikePuorro]

I don't like multiverse theory, seems like a catchy cop out to me, but this the best presentation to layman I've seen of it.

[EllieM_Travels]

This is the second time I’ve watched this, and I’ll probably watch it again. So fascinating! Thank you for providing this for us to watch for free!
