comment Special Relativity Second Postulate
I don't think that proper time has to be real. If the proper time of two event is real than it correspond to an interval that you can always find an inertial frame in which the two events happened in the same place but in different time. If the proper time of two event is imaginary then you can always find a inertial frame in which they are simultaneous but happened in different place.@JohnRennie

comment Einstein's postulates $\leftrightarrow$ Minkowski space for a Layman
Can you give a more mathematical reason why the area of the parallelogram is $c^2$ Dose it corresponds to the minus sign in the Pythagoras's Theorem?

Awesome proof. Did you invented it? If not please give me some external link @RonMaimon

comment Reason for the discreteness arising in quantum mechanics?
You are saying that this question is not answer able by reason. You have to depend on experimental truth. Right? @HalSwyers

revised Do photons interact only with single particles or can a single photon be absorbed by 2 or more particles simultaneously?
I edited a misspelling.

comment What does QM say about the past rather than the future?
I think, your question is not clear. You should ask more explicitly.

comment Many world interpretation on test
If they are different you can't observe them experimentally. So is it real if you can't see it? @AsphirDom

comment What is the meaning of speed of light $c$ in $E=mc^2$?
c is just a conversion constant or you can say it proportionality constant. Energy and mass are the same. When c=1, E=m

comment Reducing the Tsunami impact using Nuclear bombs
Is it a practical idea to tune the time of bombing so that we have exactly 90 degree phase difference? @tpg2114
