comment If infinite amount of different strong particles were to be confined and jammed together, what would occur?
Again, that is a black hole. Yes, any sufficiently dense collection of matter becomes a black hole.

comment A question about motion and time dilation
@user43783: Congratulations, this is what General Relativity is all about. Begin by remembering that there is no absolute position, and no absolute time.

If you are thinking that electrons are small balls of stuff with empty space between them, and that you could push them together so there was no space, that is not the right picture. Electrons exist in fuzzy clouds of probability, they already overlap all the time anyway, there is no 'empty space' to put more electrons into, and all you would be doing is raising the potential energy of the system. Thus, if a supernova can't do it, neither can you...

If you have forced enough matter together to form a black hole, you will form a black hole. It may well evaporate if you haven't compressed enough matter together. I don't understand your statement about a vacuum full of particles; that is not a vacuum.

comment Why does iron sink in molten iron instead of floating?
I think your densities are wrong. At present you have a higher density of ice at 0 C, which would make it sink.

comment Where on Earth does the mass of 1 kg actually produce a 1 kg reading on a digital scale?
+1 for mentioning calibration. Calibration calibration calibration.

comment Correct approach for calculating excited states of circular quantum dot under effective mass approximation
I've added the equation, explanation, paper details and fixed the title so that people can see what it's about.

comment How does an electron move around in an orbital? Is it “wave-like” or random?
FYI, calculating the surface within which there is 90% probability is actually quite challenging unless the orbital is really simple and analytic. So usually what is plotted is just an isosurface on which the probability density is at a given figure, because that's much easier.

comment Is speed of light and sound rational or irrational in nature?
Regarding rationality of numbers in measurement, David Z's answer is spot on. If you are trying to grasp whether the universe prefers integers, then yes it does. Things like the resonance frequencies of strings are in strict integral relationships (f, 2f, 3f, 4f). Quantum physics is also based on integers; the idea of quanta itself is that nature is lumpy rather than continuous.

comment Classic home experiments for an 8-year-old child
Exactly. That's one of the things that I feel makes for a good learning experiment; there is space for multiple hypotheses, and people usually get it wrong the first time. I remember being sure it would miss, partly because it seemed impossible to hit it every time. Ping. Clatter. Gasp!
