you mean... "sound"?

What does your frame of reference move relative to?

comment Electron in strong magnetic field
The premise is not correct. If we try to artificially confine the electron to a precise position, then its momentum will become completely uncertain (precisely because of the uncertainty principle), and it will necessarily escape from confinement.

comment Does someone falling into a black hole see the end of the universe?
Additionally, this excellent web page describes transformations from Schwarzschild coordinates to KS (among others), and includes animated GIFs of morphing between the two coordinate systems, which helps tremendously with intuition.

comment Time difference in transmission of AC and DC
If you're asking if AC is more efficient than DC for power transmission, then you should state that in the question! There's certainly plenty of material about this on the web.

comment Time difference in transmission of AC and DC
If I shine two flashlights at you, one with a constant beam, and the other with a pulsating beam, which beam would you see first?

comment Time difference in transmission of AC and DC
Per our discussion in Meta, this is a good example of a question that is not very clear, seemingly random, and totally unresearched.

...the article (to which you linked) describes exactly how the atom was imaged.

comment Can quantum entanglement be a proof of a 4th spatial dimension?
It's vastly more complicated than that. en.wikipedia.org/wiki/Quantum_entanglement

comment Have we found a Higgsino?
...because the particle that we discovered is, in fact, a boson. So, as you correctly state, the Higgsino would have to be a fermion.

comment Does a heavy body move with the slightest force on a frictionless surface?
The answer is correct, but I'm not sure I'm following your argument by contradiction. All you need to say is "conservation of momentum".

comment Do water movement in the seashore represent waves?
This represents a wave in the same sense that any other oscillation of matter is a wave. Why would you think it doesn't? Do you think a swinging pendulum represents a wave? How about a tuning fork? Or air temperature throughout the year?

comment What is the opposite of the Planck length?
Planck's constant is necessary because it describes the quantum-ness of our world. Planck length is simply a length unit derived from that constant. However, quantum effects become insignificant on macroscopic scales, so there is no direct analog of a "large-scale" quantum constant.
