Consider three observers in different states of motion relative to a black hole:
Observer A is far away from the black hole and stationary relative to it;
Observer B is suspended some distance above the event horizon on a rope, so that her position remains constant with respect to the horizon...

In quantum mechanics, a probability amplitude is a complex number used in describing the behaviour of systems. The modulus squared of this quantity represents a probability or probability density.
Probability amplitudes provide a relationship between the wave function (or, more generally, of a quantum state vector) of a system and the results of observations of that system, a link first proposed by Max Born. Interpretation of values of a wave function as the probability amplitude is a pillar of the Copenhagen interpretation of quantum mechanics. In fact, the properties of the space of wave functions...

What I understood is that probability amplitude is the square root of the probability of finding an electron around a nucleus, but the square root of the probability does not mean anything in the physical sense.
Can any please explain the physical significance of the probability amplitude in qu...

Often we get questions of the form
"How to build this particular device?" or
"Why was this design implemented in such-and-such product?"
Are these questions appropriate for Physics Stackexchange?

British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law is the best known and most widely cited:
When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong.
The only way of discovering the limits of the possible is to venture a little way past them into the impossible.
Any sufficiently advanced technology is indistinguishable from magic.

All three laws appear in Clarke's essay "Hazards...

How do I come to this question?
Einstein´s relativity means, there are observable phenomenons that have to add to reality relativity of time so the theory would not fall apart. My question is, is time relativity real or is there other thinkable and workable explanation for the phenomenons. Like ...
