comment Physics without time
See en.wikipedia.org/wiki/The_End_of_Time_(book), en.wikipedia.org/wiki/The_Unreality_of_Time, en.wikipedia.org/wiki/Eternalism_(philosophy_of_time). Pretty philosophical, I believe. Therefore: plato.stanford.edu/entries/time.

comment Yet another double slit experiment
1) Aren't the Fraunhofer slits qualitatively wider than each of the double slits? 2) Possibly interesting thought experiment: What if screen 2 is a perfect mirror?

comment Why may an air passenger experience an electric shock when he touches the door knob of the toilet of an aeroplane flying at a high altitude?
Maybe because of the blankets that they hand out. en.wikipedia.org/wiki/Static_electricity en.wikipedia.org/wiki/Triboelectric_effect

comment What is the exhaustive set of experiments a quantum theory has to satisfy?
Explaining the outcome of the double-slit experiment is sufficient.

comment What is the reasoning behind the idea that light cannot escape from a black hole?
Because (as you noted)... it is the definition of a black hole. Not a lot of deduction there.

comment Will an object falling into Earth's orbit start spinning?
"The answer to your question is that to a first approximation the direction of the spaceship will not change, so the upper diagram is the correct one." If we think of the spaceship consisting of two unconnected parts (maybe balls) closely following each other (on the same trajectory), then the direction or the pair will change. So, how's that different?

@user2914191 I think the question may be reduced to: How will two balls in close succession travel? What if the two balls are connected by a weightless (but fixed-length) rod?

comment Why would a black hole explode?
@DavidZ Sure. This answer was the first answer (and was even accepted for a short time). Rob's expert answer wasn't there yet. I didn't know the answer to this (for me) interesting question, but the quick Wikipedia finds were quite satisfactory for me, and I suspected, to more people. (I already chose to quote the relevant bits instead of commenting with the links only.) Don't expect an edit (from me). Feel free to remove.
