The End of Everything with Dr. Katie Mack Part 2
How did the universe evolve, and more importantly, how might it end? To find out, Dr. Charles Liu and co-host Allen Liu welcome theoretical cosmologist and astrophysicist, Dr. Katie Mack, author of the recently published book, “The End of Everything (Astrophysically Speaking).” In Part 2, we look at dark matter, Gravitational Memory Effect, and more. (You can watch Part 1 here: ruclips.net/video/V_C0m8bG_08/видео.html)
We dive right in with a question from David: “I was wondering if any physicists have looked into the idea that the “empty” space in an atom is actually “filled” with dark matter. What experiments could be done to prove or disprove this hypothesis?”
In order to answer David, f...

    cool vid, add this to ur hilbert space :) may I offer these tidbits from the Popcorn Model of Nature's Reality. This is in the study of the Harmonics and the Harmony of Our Universe in the context of Everything: so, lets use a metaphor where 1 musical note, (*) , represents Nature's Reality; This note, (*) , represents the true existence of Nature's reality. This is the realm of the lord, the almighty GOOD (not a religion but an attitude). The real note in which everything resides. What follows are just harmonics of the supreme existence of reality. 1st harmonic of reality (hor)* the human mind and the MotherVerse. 2nd harmonic of reality * commonly referred to as our universe and where electromagnetic radiative force is dominant. 3rd hor * dark matter, the strong nuclear force dominates. 4th hor * the weak nuclear force dominates. 5th hor * gravity, where the popcorn really explodes. 6th hor * time, the here and now where the rubber meets the road. The 3rd, 4th, and 5th combine to create Dark Energy. This not everything. Undescribed harmonics extend, ad infinitum, above and below the note (*). The harmonics show that space that appears empty is never in fact empty. Between Nothing and Everything is Something :)

    My theory Is that Gravity Is born of the Solid State. When subatomic matter overheats and switches Atomic electromagnetic spin around the nucleus ⚛️, such internal subatomic spin must now reconfigure itself into a polarised solid, with no more spin, instead a North and South Pole with a nuclear energy Plasma core. Gravitational Force Is basically the baby of the Electromagnetic Force and the S&W Nuclear Forces. Quantum Gravity being too weak to add mass, cannot overcome the stable Subatomic Spin. But once overheated into solid Mass, Gravity begins to have more Power, enough to gather more mass, that cannot be combated by the rigid polar regions and a nuclear core, as opposed to the Proton Electron Neutron spin around a Nuclei remaining stable, and too strong for quantum gravity to interfere. The State of Matter change causing a readjusted Electromagnetic and Nuclear process likely enhances Gravity. Which Is possibly why they’re still considered stronger Fundamental Forces even in the Astronomical. Congratulations, it’s a beautiful baby Gravity. Have you chosen of a name yet?

    Liu, I've gone beyond. Have you ever wondered how a direction stores and passes on positional values or data from other directions? Say that you have a forward ticking direction from 1 tick to 10 ticks. It has no other directional storage, so anything else is null or non-existent. If you introduce an upward direction, you'll only be able to use upward values for upward direction. So, how does forward know where to meet upward on a graph? Unless there is something else connecting them ,or there is a general direction that stores any directional value, because I can't say that this forward at 9 has an upward value of 3. Forward is only one dimensional and never has an upwardness ever. What do you think? You can tell Neil that I asked if he knows anything about it.

    • @Darker_Void_Scientist
      @Darker_Void_Scientist 3 месяца назад

      Even if I rotate the forward directional vector super fast to mimic a two dimensional circle, it won't be able to move upward.

    • @TheLIUniverse
      @TheLIUniverse 3 месяца назад

      Hey, Allen here! This is a super fun mathematics question that gets into the realm of linear algebra and topology. Usually when you have a system with two variables there's one obvious way to describe the system, but there are other valid descriptions as well. If I have 9 apples and 4 oranges and I wanted to describe that with a pair of numbers, I would usually say (9,4). I could instead, however, say I have 13 total fruits and 5 more apples than oranges and describe that as (13,5). As long as I know the math to convert from one system to the other, I can use either just fine. The math of linear algebra says that changing your reference frame for your position in space, like for example by rotating, moving to a new location, or changing what speed you're going, is just changing which numbers you're using to describe the same underlying system. So if you rotate yourself so "up" and "forward" change for you, your new up and new forward are just different combinations of your old up and your old forward. Isaac Newton figured out that what makes space so special is that there's no one "up" and "forward" (or left and right) that's more special than the rest, but that any perspective where you aren't accelerating is equally valid. Physicists say this as that there's no "preferred reference frame". Albert Einstein realized this more generally applies to the combination of space and time (spacetime), but you have to treat time as in some sense the negative of the three directions of space. It's pretty cool that by thinking about these questions we can get to the same problems that made Newton and Einstein's careers. What makes them so important to science is that they figured out the math and the experiments to back it all up and confirm their ideas.

    • @Darker_Void_Scientist
      @Darker_Void_Scientist 3 месяца назад

      @@TheLIUniverse I appreciate your reply Allen, but I'll have to respectfully disagree with some notions and agree with some. Fruits, and equivalence of rotation to acceleration with shifting positions, I agree.Yet, I don't know if it is accurate to assume there is a more general direction because we still haven't answered how a forward one dimensional vector reacts to an independent upward one. Isaac Newton's notion of non-acceleration frame, negatives..., I do not agree while residing in a rotating galaxy. Both Einstein's and Newton's notion that there is no significant preferred directional vector over another... I'm in total disagreement, Allen Liu... respectfully. Later on, I'll clarify myself to LiUniverse with real and thought experiments that even you can do anywhere at anytime.

    • @TheLIUniverse
      @TheLIUniverse 3 месяца назад

      Totally ok to have respectful disagreement - that's how we build knowledge as a planet. I will add that the rotation of the galaxy does matter but it's a very slow effect since it takes millions of years to spin once. Even detecting the rotation of the Earth on the scale of a few feet or meters is doable but hard - you can watch Veritasium and Smarter Every Day's video on how they found the Coriolis effect in a kiddie pool to get a sense of just how hard. So standing on Earth is very close to being a non-accelerating frame, even if it's not quite there. --Allen (Also P.S., would you want us to talk about your question in a future episode?)

      @@TheLIUniverse Sure, you can use it. It's okay to realize going from 0.00000001nm, 0.000000012nm, then 0.00000002nm is still acceleration. It's not a matter of scale in size, but the progress and tracking of moving from one location to another. Acceleration is acceleration. Isaac Newton's integrals should be ignored then if that's the case.
