    • Imagine how lucky we are to have in our body mechanisms that can translate electromagnetic waves with different frequencies and wave lengths into colors to see our ironically beautiful colorless universe, acoustic waves into vibrations in the eardrum that our brain translates into sounds something which doesn't even exist in the world but was defined by humans, a huge system that covers every millimeter in our body and responds to internal and external forces by sending electric signals to our brain, and of course amazingly complicated connections between neurons that create an enormous structure of information stored in an unbelievably small place. After all this, it feels wrong to call even the stupidest person in the world, stupid.

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

    • Is the universe all the matter that exists, or the space that the matter exists in? If it is the former, and the galaxies and nebulae are moving away from each other, maybe it is the outward motion or expansion of matter that is infinite. Space then is absolutely nothing and the 'universe' only exists as long as matter itself exists.

  • “The most merciful thing in the world, I think, is the inability of the human mind to correlate all its contents. We live on a placid island of ignorance in the midst of black seas of infinity, and it was not meant that we should voyage far. The sciences, each straining in its own direction, have hitherto harmed us little; but some day the piecing together of dissociated knowledge will open up such terrifying vistas of reality, and of our frightful position therein, that we shall either go mad from the revelation or flee from the light into the peace and safety of a new dark age.” "H.P.

  • The way Prof. moves from objectivity of science to the deep philosophical questions attached with space discovery is just seamless, and just shows the balance one needs to strike between objectivity and subjectivity. Without losing the magic of the universe and without making the errors of religion, he amazingly brings out the spiritual journey that he himself has been through, so that we can be through it as well.

  • I've been around this subject of infinity and the multiverses (local or temporal). The concept that everything that may happen happens an infinite amount of times through infinity isn't new for me. That been said... One and an half year ago, my 8 months old daughter choke with a piece of toy. When she was turning blue and passing out I did what was like impossible, I grabbed it with the tip of my fingers through her tiny mouth and throat and pulled it out. I hurt her so much that my wife and I had to take her to the hospital right after. My baby took a week to fully recover. But something was off. When everything was in the balance, I felt like chance did it. It was highly improbable. It just happened independent of anything. I had many nightmares after that of me living my life after this event gone wrong. I even had a nightmare about a funeral, and that frightened me the most. It's like that in many other probable universes the outcome was definitively bad. How lucky am I to exist in one of many universes where I can see my daughter grow up? So in this infinite fractal of chaos, I'm the luckiest man there is. :) Be grateful for what you have, an infinite many others of you may didn't get that chance.

By that definition, what you have created with this video is one of the purest pieces of art I've yet to experience. Simultaneously hopeful, wonderous, nihilistic, and distinctly unsettling, all at the same time.

  • I love how this channel always leaves me with more question than answers, the shape of the universe could be something we never understand and it's nice to have some mystery left, I've always thought of it as a spherical, if the universe was born from the big bang and we use points of references we can visualize from things here on earth like nuclear explosions then my small mind would expect that the same governing laws of physics to in turn relate itself to the shape of the universe going outward in all directions and then I watch something like this and I'm back to square one having no actual clue about whats going on and being snapped back to reality of bills work and life, I thank you for your channel and the respite I get from the daily grind, even if I may never understand it all, the daydreams I engage in afterwards are a little piece of happy you bring me with each video, keep up the great work!
