I only have one complaint about the entire series. 1. They are not 4hrs long. I hate when they end. The series evokes the mind to wonder about the universe and our origin and our eventual extinction. More please.

I hope I can have even the tiniest fraction of determination that this dude had, going from being made fun of by his Physics teacher to getting a Nobel prize.

I cannot recommend this channel highly enough. Thank you for your tireless work and proof that not all of YouTube has dumbed down. This has arrived as I lay in bed recovering from an accident that has laid me up for a while, so a great big thanks 😊 👍

[bennettlewis]

Simply put, I understand nutrinos significantly better now than I did 45 minutes ago. Ergo, I understand the universe better than I did 45 minutes ago.

Thank you!

Timely mention of SOFIA as it will be decommissioned after its latest flight is over, 5o be replaced by the James Webb Telescope. Yet another excellent video.

[MrMikey]

This has got to be some of the very best content on YT. Hope u never feel like it's been explained enough to stop. Pease n Love

[volkhen]

I always listen to these when I fall asleep. Then I need to watch it next day again because I sleep after 5 minutes. Not because it’s boring but soothing ;)

[muaral-rasheed]

Can't get enough of this channel. EPIC. I literally check it everyday hoping for a new video to watch while I eat and then later to falls sleep listen to it.

[GoldReefCity]

I’ve watched this three times. Well done! Good show young man! There are far too many channels that pretend to give facts and explanations. This channel is quality. Thank you for posting!

[notgreatatdota]

Thank you for this fascinating masterclass of youtube documentaries!

[Seventeen_Syllables]

If more people watched this channel we may not know any more about the universe than we currently do, but we would grasp how much we don't know so much better.

[muahmuah]

As an aspiring physicists.... we are currently in dual nature, atomic and nuclear physics and videos like this truly helps in understand what we are learning rather than simply solving equations

[edmeko]

Excellent bit of science. Perfect blend of pictures, people, history, voice explanation and style … really makes science come alive. Thanks

Oh I’ve been waiting for this, it’s finally here! I love this channel, and it’s sister channel history of earth. Keep cranking out the amazing content you all.

[passintogracegoldenyearnin]

Neutrinos have been used as a predictor of light from supernovae because their weak interactions allow them to travel faster than light through clouds of intervening matter. As weakly interacting particles they do no scatter large amounts of Cherenkhov radiation in the same way as matter jets from black holes.

*The problem with using neutrinos to peek into the past is that the neutrinos we are seeing should be **_younger_** than the photons that are finally reaching us.*

[jonova]

I am beyond obsessed with this channel. Every time I see a new video is out I get so giddy 🥰

[Cladisio]

I get giddy every time this channel, history of the earth and voices of the past release a new video.

The intro with St. Augustine gave me feels that had only been achieved by a BBC documentary about Bach where they were playing the Goldberg aria while showing a shuttle launch and simultaneously quoting Lewis Thomas.

Outstanding content. Maybe the best I've ever watched. It sets the bar at an almost unreachable height.

I always fall asleep to these videos, both absolutely comforting and fascinating, and when I wake up I usually go back to the last thing I remember and watch the parts I can’t recall in the morning. Great narration and always great topics. Excellent work!
