    "legions of astronomers" no one ever gives thanks to the Engineers/ experimental physicists.The workhorses that make the vision tangible.

    picture a guitar string (wound) and imagine the little windings going around the core wire. Now take this string and wind it around a thicker string to an indefinite length. We shall call the "e" string, imagine that it too begines to coil around a wire, it too creating a seemingly never ending length. We shall call this new string, string "B". Now imagine this B string is getting kind of long so we too must coil it for the sake of saving space, so this B string is wound around a thicker wire and then coiled off, to a very long length and now that we have this new string visualized, we can name it string "G". Now this G string is kind of thick, but if we zoom out proportionally to our imaginary presentation, we can fit it onscreen. This G string of very, very, long length then has the privilege its predecessors had as well to be coiled onto another thick wire. If you are still keeping up so far, we have labeled this newer string as the "D" string. This D string consists of a very, very, thick core with a winding of a G string consisting of a very thick core wire with the B string wound around it, it too consisting of a similar matter of the "e" string going around a core wire. Now that we have a very, very, thick "D" string, we can go even further in, and wind this D string around an extremely thick core, this new extended length of wire shall be called the "A" string. Now that we have A string finally constructed, we can conclude our depiction with the final detectable iteration. The Low "E" string. which consists of the A string wound around an outrageously thick core. At this point we have reached the scale of so called string theory and the little stringies at the bottom of metrology are now visible through the lenses of the particulscope.

    I dont believe there's an end of the universe. For example, back in our passed we thought if we would take a ship and go over see, we would fall of an edge. I do believe there where multiple big bangs over time. That would make the universe never ending.

    The universe is infinite. A sphere or elongated vast endless bubble of recycled matter at lest 1000 billion light years circumference. Its impossible to travel those distances and to have some kind of wall or screen ending the universe.

    So somewhere there is an infinite you version out there that followed their true aspirations and didn't make all of the mistakes that form the biggest regrets..

    One must remember that time is a human invention. James Webb will prove that the universe is infinite. The Big Bang is nonsense. Warp drive... oh man.

    What pisses me off is that my 16 year old grandson watched this video with me, and then re explained it to me as if he wrote multiple dimensions for dummies

    I’ve always thought that the universe has a finite amount of matter and an infinite amount of space. If the universe is a closed system, then that means it will have the same amount of energy or matter inside at any given time, but it would have infinite space since the matter in the universe is expanding outward at the moment, and may not stop doing so.

    The universe absolutely terrifies me, not many people even think about it and just get on with their lives it’s ridiculous. I’m 19 now and it’s so scary how I’m getting older and older and will eventually die and will not find out out what else there is, I’m literally begging for aliens to visit earth and tell us everything. Life is too short it’s stupid. I really want to find out wtf is happenening

    Cool. Don't know about y'all but all my great thoughts equal a grain of salt that can be divided and divided into nothingness. So that's pretty humbling.I get the feeling we are looking through a keyhole from a distance that doesn't allow the full view, but we can't help but to peek and try to get closer. Last few seconds was very nice.

    Thank you so much for these videos! for a long time the only source of spoken and presented cosmology physics has been what is shown on tv what I would call "pop science" were concepts aren't explained and discussion isn't part of the presentation. And that bled onto youtube, so i'm really happy to have found your channel!

    Also, the collapse of the universe is possible. So…. I don’t think it’s just one universe.

    Why infinite? Why not infinite? Is one more shocking than the other?

    Sometimes i get a bit confused why we're told the universe is some 14 billion years old because we see stuff 14 billions light years way. One is measured by our established clock, which has nothing to do with light, the other is established by how fast light travels. So 14 billions years is not the same as 14 billion light years. I may be overthinking it, so i'll go grab another scotch and bail out. I'm pretty sure this is not something so obvious.

    The simulation theory is like hitting the easy button. But, could be accurate.

    Your eloquence and perhaps your dialect destroys the automatically generated subtitle...which I often use as a non native speaker. Very nice scientifically poetic video. I hope I write no crap...I speak more Genlish...😂thanks for the upload. Greetings from Germany.
