What happens to quantum entanglement when one particle crosses the event horizon of a black hole?
I’m curious about the behavior of quantum entanglement in extreme scenarios. Specifically, what would happen if we sent one of a pair of entangled particles (say, a photon or electron) across the ...

What would one use a theory of quantum gravity for?
I am generally wondering how useful new more ambitious theories would be considering that even with standard non-relativistic electrostatic QM one usually has to employ unsatisfyingly crude ...

Can black holes exchange Hawking radiation, avoiding complete evaporation?
I was wondering if it would be possible that, as a black hole radiates its mass as Hawking radiation, another black hole could absorb that radiation and then when the second black hole radiates its ...

Is it possible to have a stable black hole that does not evaporate?
Black holes would presumably evaporate in the long future via Hawking radiation.
However is this inevitable? Or are there any mechanisms that would compensate the lost mass due to Hawking radiation ...

What happens to entangled particles at a Black Hole? [duplicate]
I am probably going to ask this wrong, so please don't flame me. I am not a scientist or student....
If an entangled particle enters an event horizon but has not reached the singularity, can we still ...

How fast would a hypothetical microscopic quantum black hole evaporate with an effective mass of two protons?
According to the analysis shown in this research here, see link the evaporation time can be calculated in seconds using this equation:
$$
\begin{array}{l}
t_{\text {evap }}=\left(\frac{5120 \pi G^2}{\...

Why can't the answers to equations be infinity?
When talking about black holes and singularities, most books say that combining relativity and quantum mechanics gives the answer of infinity in some equations. They also say that:
Infinity is the ...

Can black holes be expressed as elementary particles?
I recently read somewhere that black holes with their radius (Event horizon's of course) being equal to the Planck length and their mass equalling Plank's mass, the black holes can be treated as ...

What happens to those parts of the amplitude that are not inside the black hole? [closed]
Assuming that a sinusoidal wave with an amplitude a million times bigger than the diameter of a black hole enters a black hole, what happens to those parts of the amplitude that are not inside the ...

How is a black hole compatible with quantum theory? [duplicate]
A black hole has a radius of $R = \frac {2Gm}{c^2}$, in this context, if we take a single proton and neutron as a black hole, its Schwarzschild radius will be near about $4.8 \times 10^{-52} \mathrm{m}...

Quantum entanglement wins or black hole wins? [closed]
suppose: you have 2 particles "entangled" with each other, one of them is dropped by you into a black hole. Ignore any problems with the particle during its entry into the black hole. The ...

Can we use entangled particles to find out what is going on inside a black hole? [closed]
If you throw one entangled particle inside a black hole can we know what is happening with it from looking into another entangled particle outside the black hole?
How this puzzle is related to ...

Where does the black hole firewall energy come from?
There are a couple threads on the firewall paradox on StackExchange, however I have not been able to find one that explains the physical origin of the firewall in black hole evaporation.
There is an ...
