Question what happens to quantum fluctuations at absolute zero do they cease, reduce, become more spaced out, accumulate more/less energy, last longer etc etc ? at 2.7 kelvin are they noticeably different ?
Could the gamma ray bursts occasionally detected be evidence of mini 5 dimensional black holes exploding. https://en.wikipedia.org/wiki/Fermi_Gamma-ray_Space_Telescope
I find it difficult to take anything seriously if it's based on Spacetime - Minkowski's 4D model leads to all manner of unnecessary problems with time. There is no actual time in Spacetime - nothing ever moves at all (unless you add Newtonian time to it to control the rate at which things move through the time dimension), so it is just a special space dimension in which everything has infinite length. Time is Newtonian, and it stretches back before the big bong. What happens to the imaginary "time" dimension there is a distraction away from the real physics that must actually have been involved because there is no time dimension.
When you get weird stuff happening in black holes that leads to stuff supposedly disappearing out of the universe, it's just a fiction that comes out of the reality that GR's nothing more than a warped mathematical abstraction.When something falls into a black hole, you can calculate how it supposedly crosses the event horizon and falls down to the singularity, its clock continuing to tick at one second per second unslowed, but in reality it is slowed to a halt. For it to reach the centre, or even just to cross the EV, it would take more than an infinite amount of time as measured by the rest of the universe, and the universe continues to play with that black hole for countless trillions of years, merging it with others and then evaporating it away through the Hawking radiation process, all while the falling thing is still falling towards the centre. In reality, things that fall into a black hole remain suspended at the EV (or where the EV was at that time) for the whole time that the black hole continues to exist in this universe, and there are no singularities in black holes - they can't form until after more than an infinite amount of time has gone past, and by that time, they still can't form because the black holes have evaporated away. There are no wormholes - the content of a black hole is simply a spherical volume of space throughout which the speed of light is zero and any matter contained there is locked in place by its inability to function or move, while the presence of that matter and energy keeps the local speed of light down to zero.
The atomic clocks on Global Positioning Satellite Systems run typically 1.5seconds slower than those on earth and need continual adjustment otherwise GPS systems in peoples cars would not be very accurate. Einsteins Field Equations are a very accurate model and clearly show time does slow down in a gravitational field, they accurately predict the existence of black holes, I am inclined to believe them, except where they disagree with the various quantum theories.
Time is Newtonian only in your reference frame, time slows down and speeds up.
Time itself emerges from quantum field theory as does spacetime.
Most of what you are talking about here is relative to the viewers position, depending on if you are the entering the black hole or the observer.
The weird stuff is the interesting stuff, time dilation is pretty well understood, but the weird stuff is what causes people to speculate including I think Einstein Podolsky and Rosen, in their EPR conjecture which goes some way to explain non locality and quantum entanglement. As you must be aware there is a lot of work going on in quantum computing and cryptography which relies on entanglement, or spooky action at a distance. Wave particle duality regardless of which https://en.wikipedia.org/wiki/Copenhagen_interpretation you accept happens.
To get ones head around where matter comes from in the universe one has to go back to pre the planck epoch. Hawking theorized about a space time without the time dimension just before his death. All of space time today is full of quantum fluctuations/virtual particles gravitons? call them what you like. The casimir effect proves the existence of quantum fluctuations. Before our observable space time expanded there was a spacetime without particles of any kind. The laws of thermodynamics apply everywhere, energy can not be created or destroyed, therefore the overall energy of the universe is a big 0. This is got around by taking gravity as -ve energy and all other forms of energy as being positive energy.
The big bang states all matter came out of very hot radiation ie bosons that appeared from now where and then miraculously formed into quarks and fermions etc. There is no evidence that a photons can form into particles, they can knock particles out of matter, and raise its energy level. An electron and positron can form into gamma rays, the process can not be reversed in the lab. It is blithely claimed that photons can convert into particles, it has never been done. So where do particles come from?
... Which when looking at the idea that matter is formed around micro blackholes which can be entangled, see EPR=ER conjecture, seems plausible.
Thanks for the response by the way, I am getting bored talking to myself
Edit photons have gravitational fields as does all energy, they are emitted from atoms when electrons fall to lower energy levels in the atom. Is that also a chicken and egg maybe like the gravitational energy given of by black hole mergers, could that gravitational energy also have carried of an equal amont of photons or mass from the black hole merger.
If you can turn an electron and positron into gamma rays, there's bound to be some way to turn electromagnetic radiation into those particles, but there's no guarantee that it can be done by feeding in gamma rays of the same energy as come out.
This again points to the reality that all matter must be spread out and not all located in a point, so a lot of it surrounds the visible part of the matter like a dark matter cloud, and that part stays out of the black hole.
Gravity is not a force in the LET model if you consider matter to be made of waves
