The fact that this is free on YouTube instead of on television says a lot about what kind of people you guys are. Such a simple act of kindness

Getting home from work at 3am and discovering a 2 and a half hour video that I have to watch immediately. Love your work.

[Yerpyerp]

"the alleged comedy show 'the big bang theory'". Damn, shots fired

[aiforculture]

I'm so grateful for this channel. It feels like being guided by a wise and ancient friend into a story I'm already a character in.

I save these videos to sleep at night. It's not that they are boring, quite the opposite, they are very interesting and engaging which helps me not to overthink my day and just curiously listen in peace. Excellent narration and information.

[ColdViolet]

I'm going through a really tough time and your videos genuinely always bring me such peace🫶🏻. Thank you for producing one of the highest quality content on YouTube.

It's amazing that we get this quality of education for free. Thank you gentlemen and ladies of the academic world to pass the knowledge along to the younger generations. And ofcourse thank you, sir Kelly, for your impeccable narration as per usual.

“You can’t eat this without smiling” must be one of the best compliments you can give a chef.

It's difficult for me to express in words the sensation of satisfaction that basking in the experience of this masterwork makes me feel. I have a feeling like that of laying out in the sun on a pleasant day with clear blue skies surrounded by beautiful, verdant nature (and not being irritated by biting bugs, wildfire smoke, obnoxious people or any of hundreds of irritations) in quietness and serenity, the only sounds being those of a gentle wind blowing the leaves of trees. I have the feeling of ingesting something profoundly wholesome and "gently wonderful". The feeling of calm serenity is aided by the perfect background music and the calm, reassuring voice of the narrator. This video you all have produced is magnificent and the subject is awe-inspiring. It is an exceptional gem of science and even reality education and communication. The video and visuals, the gentle and beautiful background music that goes so far to put a human's nervous system into a state of receptive calm, the scope of the work, the narrative pathway through the long human quest to understand reality, the lucid, flowing explanations that seamlessly and gracefully flow from one subject to the next, the calm and steady pace of a genuinely pleasant narrator's voice, *not* chopping it up into "shorts" or 15-minute segments but taking enough time to tell the narrative story from beginning to end and trusting that there would be an audience with interest and attention spans to listen to such a masterwork...
.
I could go on. This work is a masterpiece, an absolute gem, profoundly nourishing to intellect and soul. Thanks to all who created it and have blessed me with your intelligence, knowledge and skillful efforts. I predict that science teachers all around the world at many levels will refer their students to this masterwork for as long as it's available. Again, thanks to all who worked to create this masterpiece.

Best narration ever. Right up there with Werner Herzog. No joke. Sometimes I love the internet.

[Wanttofanta]

The fact this video is 2:32:23 long is tripping me out for some reason.

*Labor Day weekend is put on hold.
*Planned chores are postponed.
*New design pieces sitting on my work table in the studio will have to
A NEW 'HISTORY OF THE UNIVERSE' JUST DROPPED!

DND!

[xxEasydoesitxx]

I feel like this channel does its small part for mankind. 🌎🍏

[abacate_com_limao_]

This channel is so great that I barely believe I can watch such contents for free, for hours, and with periodic new videos.

Thanks for your amazing work.

About the three colour receptor thing:
It has been hypothesized that humans have three colour receptors (where most mammals have two) because we need to be able to see ripe fruit. Apples are ripe when they’re red, and red is the colour that is specific to humans. Others animals see red as a sort of green.

Interestingly, this is the reason why red (ginger) camouflage works in animals like cats. To us humans, a red cat very easily stands out against the background. But to most prey, the cat appears almost fully green. (Google this, it’s very cool)

It’s the best option available since mammals aren’t able to naturally produce green hair.

Very cool if you ask me!

[Semirotta]

Just imagine how many countless brilliant and beautiful minds have been lost due to the pointless greed, war, religions.

[michaelwang]

59:13 the word "niggles" took me out lmao

[Amo]

Insane to have this kind of qulaity content for free....

I mean an over two hour long video that goes that deep and take the time into explaning basically the history of Physics from the discovery of atoms, quantum field theory, generla relativity, the most recent attempts to unify those, some philosophical toughts.

All that with quality images and videos and a top notch voice and written text.

All that for free.

Just waouh !

Not a two hour video!🤯
It's more than that?!🤩
Thank you!🙏Thank you!😭
You should have!🥰

[Kainan]

This is by far the most immersive science channel there is. The content is not that dumb either. Thanks for touching the intricacies of physics in a very simple and elegant narration.
