"It is also sometimes described as the consequence of an "effective" field differential around the body (e.g. the effect of tidal forces)." (c) Wiki
Can you please be exact about where the need for boundary (Horizon) raises? I do see only need for differential (tidal force) and strong...
I believe it is important to note that there is another type of Hawking-like radiation - emission made by spinning Black Hole out of quantum fluctuations outside of Event Horizon. E.g. there is no particular need for "boundary" (Horizon) to split particle-antiparticle.
This theoretical...
It is known theoretical prediction that Black Holes must emit radiation "... its temperature and surface gravity are proportional to its mass divided by its area" (Kip Thorne). This is applied to Event Horizon (rg).
But one can imagine inner Black Hole (e.g. inside r' < rg), it does not have...
Hello!
Dark Matter (if exists)(if it is in form of particles - collisionless) could also be attracted by Black Holes (or Neutron Stars) and form accretion disk. I would like to discuss possible properties of such hypothetical object.
DM particles could be trapped and settled in around...
