Considering a Delayed Choice Quantum Eraser experiment such as the one in the picture above: It is said that paired photons arriving at the detectors A,B,C,or D, reach the detectors after the entangled pair has reached the interference screen. Are we actually able to measure the time interval...

OK I understood that explanation. Which brings another question: if the particle can in fact resolve inside the barrier, that probability exists regardless of the with of the barrier. Does that mean that particles can tunnel inside any barrier, regardless of the size of it? Let's say there is an...

That link is exactly what I was looking for, thanks!

When I see explanations for quantum tunneling, the discussion is around the probability of an electron manifesting itself before the potential barrier, and after the potential barrier. However, looking at the curves draw, there is a non-zero probability (the evanescent part of the wave) inside...

Also another question if I may: why the horizon oscillates, instead of just increasing in size?

That's all very interesting! I'm interested in the part where you mention a "bump" on the prior horizon shape. Let's say we have the planet being captured in a very obtuse angle and goes around the center, inside the horizon, before getting to the singularity. Would this movement be visible from...

Understood. Thanks. Ok so exploring this a bit more, taking the scenario where a planet, or a neutron star, enters a black hole... for that brief period before the star's matter gets into the singularity, would this black hole have any characteristics visible outside the event horizon that are...

Thanks all for the answers, appreciate. Ok so from what I could understand, it is very well possible that the contents of a black hole are known objects, such as "5 neutron stars moving perfectly in a common center", or a "dust cloud the size of the milky way", although these scenarios will be...

If neutron degeneracy is not overcomed, black holes can't form?

But that is also true for the center of a Neutron start, correct? Let me elaborate a bit more: let's say we have a neutron start slowly gathering more matter (from any source) over time. At a certain point, this start will become a black hole, that is, an event horizon will form. At this...

Physically speaking, why the insides of the least massive black hole should be any different from the heaviest possible neutron star?

Awesome explanation. Thanks!

Thanks for the answer Bandersnatch. Why not clumping would matter? Shouldn't gravity only be enough to keep it together?

If the distribution of elements in the universe is also the distribution of elements in the solar system for regular matter, and being dark matter so overwhelmingly prevalent in the universe, why can't we see it overwhelmingly in the solar system?

Yes fair enough! So to rephrase it: In Newtonian physics, if I take an empty Universe and put two Suns perfectly still to each other, 13 Billion light-years away, the gravitational fields of each will affect and attract the other. Is that still true in GR?
