comment Why does maximal entropy imply equilibrium?
While this is arguable an answer it is a very poor one. A bald statement with neither explanation of the reasoning behind it nor anything to justify the claim.

comment Twins paradox question
Something that is very important to understand: while pop-sci books always present this as a though-experiment involving people it has been tested repeatedly with unstable particles in accelerators.

comment How does the fundamental assumption of statistical physics make sense?
Sorry. I wasn't suggesting that the work should go here (because you're right the size of the project grows quickly), but instead offering a comment for any reader who wanted to know more.

comment How does the fundamental assumption of statistical physics make sense?
The next thing to do is to consider the how the strenght of the preference for equilibrium macrostates and the width of the distribution changes as the size and energy of the system grows towards macroscopic size. You find that the preference for the equilibrium macrostates grows ever more extreme and the width shrinks toward a case that is distinguishable only with the most sensitive of experiments. It's a worthwhile exercise.

comment Why is the intensity of an alpha ray constant along a material?
Question that might lead you to the answer: what are the units of intensity used here? Several different definitions are possible, and the correct answer depends critically on which is chosen.

comment Why do some stars actually produce “Gamma ray bursts”?
As I understand it (very vaguely, that is) the detail is a mess of non-linear math arising the magnetohydrodynaimcs. How's your math and at what level would you like to be answered?

comment How can a moving point charge “update” its fields without emitting an e-m wave?
To put @CuriousOne's comment is plainer language: turn the question around. How can an observer move in the field of a stationary charge without the charge emitting EM waves? It's the same question because there is no uniquely identifiable state of rest.

comment What is a good PhD Thesis Topic in General Relativity?
My best suggestion for advice from the assembled masses of Physics SE is to answer a question or two in order to accumulate the rep needed to participate fully in chat and then bring the subject up in the h bar.

comment How does one actually use the Einstein field equations?
With great difficulty?

comment Light from Absolute 0
An assumption of instantaneous cooling to absolute zero violated the 3rd law of thermodynamics. It is seriously time for you to quit throwing idea together at random and hoping that they add up to something. Go forth and learn systematically for a while. Find out a little about how notions in physics are connected to one another and how they depend on preconditions. That is to say make yourself part of the audience of this site: "Physics Stack Exchange is a question and answer site for active researchers, academics and students of physics and astronomy."

comment Cold Solid Matter at the End of a Black Hole's Acceleration Disk?
Word soup and pictures of equation soup don't make a good question.

comment Why do we see discrete light spikes coming out from a light source?
Perhaps more direct than Johns link is: physics.stackexchange.com/questions/35935/…

comment De-broglie wavelength
You should read the links that John has given. The "homework" policy is currently construed to apply to a class of problems that are perceived to be homework-like with taking notice of how you can about them.
2d
comment Rest mass of particle of light
BTW--I know that the question asked he is not precisely the same as that asked in the duplicate, but the same understanding is needed to answer both and that duplicate has become are de facto canonical question on photon mass, energy and momentum. You'll find a few additional answer in questions from the "linked" sidebar of the master question.

comment What are these cycles in orbital eccentricity called?
If they are accurate (rather than features of a problem with your simulations), then taken together with some other factors (precession of the equinoxes...) they go by the collective name Milankovitch cycles. That article might break out the individual contributions for you, but I am officially out of my depth.

Nice expansion.

comment If you play more than one music track at once on a computer, does the sound heard get louder?
@user31782 That's essentially a physiology or cognitive question with a small but important amount of physics input in the form of noticing that the cochlea detects the frequency-space power components of the signal (i.e. it detects the Fourier transform of the time-dependent pressure function).
