  1. Cleo, I have one for you: If everything is spinning, including planets and stars why aren't they all a disc and end up being a ball? What's stopping matter/particles from becoming a disc shaped thing? 🙂

  2. I didn't understand when he said, «we don't quite know why pretty much all galaxies have super massive black holes at their centers». isn't like the sun in the center of the solar system, only orders of magnitude greater and spacetime converges there so everything «near» is sucked or orbits and is supermassive because has been capturing matter since forever and maybe are multiple back holes merged

  3. All bullshit, nothing is really possible to be verified or measured. All based in mathematical calculations. Everything can be created by mathematics, but not all is true.

  4. So, the center of a black hole is an insanely massive amount of nothing? If molecules get completely destroyed by tidal forces, then there must be no molecules at all? So, the material masses literally collapse into/become gravity itself?

  5. Sussikind seems to be at the forefront of theoretical physics, but despite his knowledge of the subject, none of his theories sit right with me. They all sound more like fantastical delusions than like the obvious conclusion given the known existing physics. ER = EPR is a tenuous connection which is rendered meaningless by its own math. Black hole complementarity is also one of numerous black hole theories which invokes an event horizon despite no physical way by which an event horizon could form in finite time. On top of that, it postulates that energy is duplicated at the event horizon with half being radiated and the other half going through to the interior. For physical black holes, sure, Schwarzchild is a good approximation of a real black hole, but that doesn't mean a literal event horizon like described in the math exists, which is why I love that Brian repeatedly mentioned "almost as if there is no interior", which is the actual most natural conclusion, given the known math and physical processes.

  6. What if a collapsing star or anything that is collapsing just remember or have the knowledge about us until now and we could use that to make many more possibilities out of.. a black hole but THIS LIFE is constantly going on ..

    TBH i think black holes are a kinda thing in this world which will remember everything that has already happened, in a weird kind of way as weird as us humans living.

    I guess the future will be between the people who wanna live in a constant time line or wanna explore more possibilities where they'll go ape shit of the possibilities in this multiverse the black holes will open us to.

  7. Imagine being Brian Cox and everyone you speak to has that look of quiet awe and fascination when you're talking. Cleo's face sums it up, she looks like she's hanging on his every word lol. Me too

  8. Does it make sense that we’re in a black hole? Would that explain why the rest of the universe is accelerating away from us?

  9. If we were inside a black hole, why wouldn't light be absolutely different in all directions? In practice, Isn't our Earth's receivable light pretty homogenous?

  10. Yes! Sir Brian Cox, Sir Jim Al-Khalili, and Sir Roger Penrose were my all-time favourite physicists, whose names I can always recall from the top of my head. Thank you all for being the genuine, humble, and simply awesome individuals who never stopped wondering, yet still never stopped believing in science as a whole! Indeed, a very special part of my heart goes out to you, Dame Cleo Abraham, Dame Sabine Karin Doris Hossenfelder, as well as many others who never stopped dreaming and questioning, driven by the belief in science as a whole.

    The order in my personal hero list is quantum, not intentionally nor unintentionally divided, right in two! <3 Lots of love to everyone! (One love!)
    (Silly monkeys give them thumbs, They forge a blade, And where there's one they're bound to divide it, Right in two.. [Maynard James Keenan – Tool, All Sirs but don't let them know! ;)])

  11. Einstein suggested that the black hole is actually the entry point for all matter that will tear apart the space time & create a new Big Bang in another universe. Thus the multiverse is born. It does follow the physics of this universe where every action has to have an opposite & equal reaction. Matter cannot just disappear it has to go somewhere, Energy cannot be created or destroyed, so the matter falling into the black hole is energy, it has to go somewhere.

  12. Interesting… (sorry about my rusty English).
    How can something collapse and still come out of a black hole, if nothing can escape its gravity?

    For example, if the Sun were to collapse under pressure, could something come out of it too?
