comment Is it theoretically possible to prevent or deter a star from becoming a black hole?
I'm afraid this is a bit like asking if we can beat the second law of thermodynamics. Yes, we can, locally, but usually it comes at the price of making things worse on a global scale. To prevent formation of black holes, you'd have to fuel stars somehow so that they can keep opposing the gravitational pressure. Or you have to strip them off of material to ease off the gravitational pressure. We are far from accomplishing feats of that magnitude.

comment Ampere's law and magnetic circuit
The intensity of the field is greater on a smaller path like that, because your loop is closer to the current.

comment Is this one of the reason we can't travel in time?
@CuriousOne "Science is a method to explain natural phenomena that have been observed. It can't say anything about phenomena that have not been observed". This is so wrong I'd like to slap your face in person for spouting such nonsense. Did Dirac observe the anti-electron when he wrote down his equations? Did Englert, Brout, Higgs, and others observe the Higgs boson before introducing the mexican hat potential? Did Galle just decide to point his telescope at a random spot in the sky and then send a letter to Le Verrier asking him to explain what he saw?

comment Can photons travel faster than $c$? (Feynman Lectures)
I'd say no. But someone else might disagree. What is certain is that it's the computational procedure that requires adding arrows for all processes. Even if they involve apriori unphysical things.

comment Can photons travel faster than $c$? (Feynman Lectures)
The arrows are representing the wave function, or rather infinitesimal pieces of the wave function of the photons. What Feynman is describing in layman's terms is the path integral in quantum mechanics.

comment Can I state that $\Psi (x_1, \dots , x_n,t)= \sum_{i=1}^n a_i \psi (x_i,t) $ via superposition?
To put ir succinctly: no you can't do that.

comment Understanding of the $m v^2/2$ formula for kinetic energy
Yes, the weight is definitely non negligible. The relationship between terminal velocity and amount of fuel will not be linear like you assume.

That's because this stackexchange has made the decision to not allow homework questions.

comment Can Quantum Entanglement and Quantum Superposition be considered the same phenomenon?
All entangled states are special cases of superposed states. But not all superpositions are entangled states.

comment What is wrong with the De Broglie–Bohm theory a.k.a “Causal Interpretation” of quantum theory?
@bright magus: If you say so. See you, I'm off throwing away all my books about classical phase space.

comment Can we use quantum entanglement as a way to send information or data?
Entanglement is used as a means to create secure communication, but the essential information is still sent through a classical channel.

comment Is there physics behind the layout of a piano keyboard?
Or better even, isomorphic keyboards.

comment Is there physics behind the layout of a piano keyboard?
The thing is, there's definitely physics involved in the workingsof a piano. But the specific layout of the keyboard is really just a convenient choice. If you search a bit for it, you'll find many other keyboard layouts that were used in history. Take for instance enharmonic keyboards. Those are way better than our more common keyboards in that you can play just intervals with them. If pure physics was the motivation to select a keyboard, we should all opt for an enharmonic one.
