"Schild" is shield. "Sign" is "Zeichen". There is too much packed into this short video to really digest. This one is more fun, and actually much more instructive. ukposts.info/have/v-deo/goGffIqCkXiFqmg.html

Visualization of the effects of just special relativity is very easy, but even that is almost never done correctly. All of my old textbooks do it wrong. E.g. the Lorentz "contraction" is purely fictitious. The problem comes when trying to visualize 4D things with 3D models. You have to stick to invariant theory in 4D space. And it's not a Euclidean space, in any way at all. I spent a lot of time figuring this all out because it was very clear to me that only confusion was being generated by the standard treatment.

Imagine if there was a white hole that our existence is pouring infinitely out of at exactly the "opposite" position for every black hole that is infinitely sucking our universe inward. And if somehow we could create enough energy perfectly at the event horizon, that we could possibly propel ourselves backwards for a split second faster than light and "bounce off" the even horizon like a trampoline into an alternate universe at the same point of the event horizon on their white hole.

That WOULD be the point at which an alternate dimension would be accessible, and would take physics bending practices to even attempt in the first place. There is a theory that if you travel faster than light, that you can break time and go backwards in it, which would allow you to enter the event horizon beyond a white hole, making both a possibility if going faster than light ACTUALLY turns back time.

Ill try and do a quick summary of the geometry of the interior of a black hole. The classic, "swirling drain" metric is appropriate for the approach TO the event horizon, and over it. But, when you approach the singularity itself, at the bottom of the "swirling drain", you will encounter the inverse shape of that "swirling drain", the singularity will be sitting atop a increased curvature space. Think of the rebound in water when a drop falls in. The only place to navigate past the event horizon, is near the bottom of the EH "swirling drain" where the space equals out between the EH "swirling drain" and the singularities "rising" curvature. These are difficult ideas to grapple with, and even more difficult to explain coherently.....

Black holes have never been observed either, despite what you hear. The most important thing to get from this talk - let's say you start with some amount of matter and keep packing more in - there never comes a time when the horizon forms in your frame of reference. Therefore either the horizon has always existed, or will never exist. There is no in between. I've never seen this question properly addressed. To me, this implies that there is a basic problem to begin with, and it likely has to do with the common origin of gravitation and electrodynamics. If that were understood, the horizons would likely disappear. We already know that gravitation lacks even a simple local law of energy conservation. That's already a showstopper way before things get weird.

The white hole seems to not really be mostly go into our world, the mass coming from a white hole seems mostly only go inside the black hole, and if something were to actually make it into our world, it would have to move at the speed of light in the infinite past. Anything not moving at the speed of light within the white hole will with most likeliness just end up in the black hole.
@ayoCC
@ayoCC Годину тому
are you really spaghettified, if gravity stretches space, and not stretching you across a given space? You're still "occupying" the same amount of space right? But at the same time, light can also be stretched when space stretches, and it changes the light so i guess we do become spaghetti.

Another part people fail to talk about is the nucleosynthesis of the very heaviest of elements. They are formed from the neutrino flux when neutron stars collide or when the most massive of stars (~100M○) collapse. The inner shell around the core is so incredibly dense, and the neutrino flux is so high from the forming and collapsing neutron star, that the neutrinos can interact with the shell and "fuse" (through neutrino capture) the heaviest of elements. The true story of nucleosynthesis is a deep and very interesting topic that is overlooked by most.

36:15 Sounds like what they're saying is that a parallel universe is just this universe, but outside of the edge of our 'visible' universe? That's why there's the ability to see the light of their universe, thus seeing their effect, while they remain outside of where we can physically go?

I got a question though... When light gets absorbed by an atom and before it gets emitted again, what does the atom do? I only know an electron will go to a different shell briefly and fall back while emitting that photon, but while in that higher energy state does the atom jiggle more? Is it possible to shed this energy by bouncing into a different atom, preventing the photon from being emitted?
@John-ir2zf
@John-ir2zf Годину тому
Yes and no. Atomic collision in such a scenario would be rare (here on earth where we see photon emission from electron field changes) because of the shared repulsion between the two atoms, or more correctly, between their electron fields. WERE they to collide, the energy could be transferred to the neighboring electron field, but that electron field would behave just as the original field and emit a photon when the electron dropped back to a lower energy level.

@John-ir2zf
@John-ir2zf Годину тому
A bit more "in depth" discussion would be to look in to the "big rip" scenario. When you look at the overall characteristics of a "big rip" endstate, you see that quarks are being pulled apart at the speed of light, and when doing so, the gluon energy will spawn a new quark of each that is pulled apart. Now, compare that to the characteristics of the "big bang" in which, all of space is expanding FTL and there was innumerable quark generation happening. I didn't major in cosmological physics, but when two events share such glaring similarities, it's worth looking in to, and very few have. Issac Arthur has touched on the topic a bit since I brought the idea up several years ago to him, but he, like myself, lacks the mathematics to dive deeply in to it.

Schwarzschild means both black sign or black shield in German. The latter seems even more fitting. Funnily if we put it as a verb "to shield" we use the verb "abschirmen" which comes from "Schirm" = umbrella. In the German dub of TOS star trek the shields are translated as Schirm (umbrella) and since TNG as Schild (shield)
