-Particles are entangled because a quantum state is entangled (like the spin of an electron). This can only happen because of some form of interaction. They will probably find several new ways of how particles or objects can interact to form entanglement...this will give more info concerning the range of separation in which particles or objects can get entangled at.
-This concerns a model called Holographic Entangled Space time. According to this model...when you disentangle two regions in
I don't think there are any theories based on black holes exploding.
That doesn't say anything about black holes exploding nor, as far as I can see about black holes at the centre of galaxies.
From the mass of the star that collapsed to form the black hole. (And, in that highly speculative, purely theoretical paper, they would be 4D stars.)
Mass is ejected from the accretion disk around black holes, not from the black hole itself.
None of this seems to have any connecti
