These video's are fantastic, I'm gonna get seriously stoned and watch this tonight.
-
I’ve literally started pursuing graduate degrees in physics because of this channel. Thank you for igniting my own passion in science.
-
Space and time are relative, the more time I spend with my relatives the more space I need
-
Hands down, this is the greatest hyper-massive black hole of all space channels. Its poetry meets physics, impeccable musical taste to boot.
-
The Einstein cans of beans story into the Hello Fresh ad transition was actually smooth af tbh
-
These videos helped me through some rough depression
-
This last civilization is not doomed to die. You see, in the year 7,040,099,620,137 AD, this civilization invented the tri-spatial multi-spasmodic negulizer beam that opened up a cross-dimensional doorway into countless alternate universes, by which the last of their people escaped. And they found paradise on the other side: a tropical planet in which they now lounge all day against the starry, sunlit heavens. 🌳🌴🌴🌴🌴🌳🌳🌴🌴🌴🌴

Honestly thank you youtube algorithm. This played in the background on autoplay. I thought it was a re-upload of something that had aired on television. This is amazing quality content.
-
This video is an absolute masterpiece. The hypothetical story, history, and science, are tied together so well that I have no words to describe it. Please accept my standing ovation!
-
Thank you for all that you do. This channel, along with your sister channel History of the Earth, have genuinely helped me through some difficult times the last year or so. Sometimes its just nice to remember how unimaginable it is that we are lucky enough to be here in the first place. Much love.
-
Lol the transition to the hello fresh ad was so smooth that i can't even hate
-
Mesmerizing. One can’t help but appreciate the brilliant minds of both philosophers and physicists, and how their different approach to seek answers complement each other.
-
These videos, along with the History of the Earth ones, are probably the best produced and highest quality on YouTube. Not only beautifully presented and narrated, it has this almost poetic quality. Then there is the shocking mind-expanding content, like undergoing a form of deep meditation. Bravo!
-
Dude this content is award worthy. From narration to script writing everything totally on point. 👌👌👌
-
I love these videos, and I have definition of time: Time is the force which stops everything from happening at the same moment.
-
The presentation and content of this channel is truly the best on the platform. My favorite part is how the ideas of advanced topics are presented without having to do immense personal study.
-
The part about "Forgetting" being the the core of entropy and what separates past and future was really meaningful to me. Good job!
-
These are less YouTube videos and more science documents that any serious science or documents channel would be proud to broadcast. This is what the BBC would have produced in it heyday. Thanks again for your tireless work.
-
This video came to me when I needed it the most. Thank you so much.
-
I love how scientific knowledge forever changes and grows with new scientific devices, and all concepts are severely tweaked if not totally replaced. Wonder what this podcast will sound like 200 years from now.
