  • I realize that there is only so much “history of the universe” that can be covered, but please don’t ever stop making these videos! This and history of the earth are two of the absolute best channels on YouTube!
  • I have multiple sclerosis I use videos like this to distract myself from the physical pain and suffering Sorry if this sounds dramatic but I'm grateful for your work
  • As a creative writer interested in poetry and creative non-fiction, the writing in these videos makes me drool. It is imaginative, innovative, and incredibly informative, making intriguing connections between vastly different scientific, historical, and science fiction topics. The writing accomplishes this while also managing to build an immersive story line that allows the viewer to relate, all while presenting complex scientific facts in an easily accessible and understandable fashion. These are my comfort videos, for times when I want to get lost in expansive language that teaches me more about my place in the universe as I fall asleep or go about daily tasks. Thank you for the amazing content!
  • @anteradic5116
    For an armchair salon physicist such as myself, high quality videos like this one are an absolute treasure.Thank you very much!

    Here's a better way to visualize extra dimensions. Think of a book. You can read left-or-right on a line of text; there's one dimension. You can skip up-or-down between lines; there's a second dimension. You can flip forward-or-backward to different pages; there's a third dimension. Those are the 3 dimensions you're familiar with. But you can also pick up a different book; that's not just a continuation of the text in the first book, it's a completely different narrative. Now you're navigating in 4 dimensions. You can go to a different section of the library, switching between fiction, nonfiction, photography, etc. Now you're navigating in 5 dimensions. You can go to a different library that has books in a different language; now you're navigating in 6 dimensions. Etc.
  • Currently going through a separation. I won't go into details because they are irrelevant. My wife is the only person I enjoyed discussing things like this with; I see the universe(s) in her eyes, and she always brought up stuff my daft self would miss. I miss her. I miss those talks. I miss being shown I don't know everything. I know a comment like this is annoying to a lot of you - probably would be to me as well - but I'm still going to say it. Have someone you love... don't just say it to them, show them. Love you, M.
  • The first thing that occured to me, was that we keep trying to look smaller when searching for extra dimensions. I am curious as to wether it has been considered for there to be larger dimensions that we are too small to observe.
  • @davidswift9120
    These videos along with 'The History of the Earth' collection are quite simply the best of anything you can watch on any platform. The poetry with which these are narrated makes my spine tingle!
  • @BloobleBonker
    I have never come across such a clear and graphically satisfactory summary of this difficult subject.
  • @mttlsa686
    the fact that someone around 2000 years ago came out with such outstanding ideas is mind blowing...
  • Great video,  have always known there’s more to life than meets the eye, I feel like in this life i am supposed to be doing more than i am doing for the people i love. been seeking for an eye opening enlightenment, a way to be more influential, powerful and protected~
  • One more time .All the hidden dimensions are right before your eyes ,and in order to see them , you must look with the all -- seeing 3rd eye . Then they will loom large in front of you, not all together ,one at a time. And you can bounce from one to the other ,each one an independent domain in itself as this world is a complete independent domain in itself .

    I would've given my left nut to have had such a wealth of good documentaries like this when I was a kid in the mid 2000s. Animal Planet, Natgeo, History Channel, etc only had so much and we all know what they turned into. The move from TV studios to individuals and small groups of independent creators was inevitable. A textbook lesson in market competition. It's just unfortunate that all these creators are stuck under a corporation like Google.
  • @Quark.Lepton
    It is very difficult to conceive of, mentally, so the best way I’m able to envision the extra dimensions in our reality is to acknowledge the fact that they really aren’t anywhere because they are everywhere. We are constantly moving in, out, through, above and below them in every instance of our existence, and quite likely in every instance afterwards.
  • @Jay-zg8zy
    Some wild "trip" I had once was the experience of a visceral sensation that "information packets" held all forms of the "constant Mind" of the universe - accessed via mental frequencies (like unique key IDs that connect you to a data point) that can be read and downloaded. It would apply to anything - any kind of information you would want to "simulate" would be there - even down to the nuances of everyday chainlink sensations you wouldn't think remarkable - is encoded in some frequency/vibrational fields.
  • @Josh-do4ln
    You genuinely make some of the most informative and entertaining scientific content. Your storytelling style is captivating when covering topics that are seen as overwhelming and boring. Appreciate you!
  • I love physics and history. This dude's narration, intellect and vocabulary are impeccable. Thanks for sharing your experience. Much love, teacher!
  • @sephjfox
    Visualizing multiple dimensions is like imagining a surgeon who can put on a VR headset and then flip through the layers of reality like a catalog to perform surgery on a person by virtually reaching into something that looks like a tree and pulling out an unwanted branch except that the tree is the person and they can't feel anything and never have to be drugged or sliced open, they can just go home healed and feeling completely normal
  • @ciarandevine8490
    Where are all these dimensions, all around you and passing through you. We create our own reality and the more open minded we are the more we unlock the truth within us. Speaking from personal experience and absolutely not from books or the programming I received as a child from parents, school, authority, religions and society in general, I’ve started to experience other dimensions, realised that time is not linear and space/distance is an illusion in this multidimensional multiverse and that’s just for starters. An open mind unlocks all doors as it realises that we created the doors blocking our consciousness, we are the key. 🌟
