comment Why do termite pellets fall in a perfect circle?
This is appropriate for an entomology site. One has to study the way the termite eats , if it is the left overs of making a hole, or it defecates, if it is that. No, it is not quantum mechanics other than everything at the bottom is quantum mechanics. ( it is not my -1 but I fear you will get more as the question is not suitable here).

comment Does exciting an electron across the band gap change either its position or its localization?
The shape of the orbital is the probability of appearing in a specific (x,y,z) within the cell , were the electron to be measured. In this sense its probable location is changed . So a qualification is necessary ", and this putative positional change is too localized to matter" ; or something like that

comment How do we know the expansion of the universe is “of space” and not “in space” or “into space” or another less intuitive arrangement?
have you understood the data that give rise to Hubble's law? en.wikipedia.org/wiki/Hubble%27s_law . " This is normally interpreted as a direct, physical observation of the expansion of the spatial volume of the observable universe"

@Bhavesh The moon is an inanimate object in space en.wikipedia.org/wiki/Moon ; scale it down . Organic matter will have extra problems as water will be sublimating out both from the sun side and the shadow side . If something alive survives long enough to feel it will be boiling on the sun side ( not just sweating) and freezing on the shadow.

@JonCuster That is what I thought, but by checking learned differently. Please have a look at my answer where a whole new world of electron beams is opened in the link

Please note that in a beam the electrons are not bound and are spatially separated

comment Why doesn't a nuclear reactor's filament deform?
Dear Bhavesh, I see that you are 13 years old and it shows in your questions. It would be better if instead of asking questions here you read up a bit on the subject before hand. en.wikipedia.org/wiki/Nuclear_reactor

comment If we hit an electron will it go to an excited state?
The electron does not become excited, it goes to a higher energy state, called an excited state. One has to be careful of terminology in physics. The electron is an elementary particle and can gain or lose energy when free through electromagnetic interactions, or go to a higher or lower excited state when bound. Excitation is an attribute of a bound system as a whole, not of an electron.
