comment Does the Night Mode of the screen display (LCD) save more energy?
I would say that the display uses more energy, as the crystal is normal non-blocking, and current is needed to make it black.

comment Metallic and glass sphere of same size released at a height
This question is impossible to answer without more information. I will down-vote for now, and return later to flag for closure or up-vote.

comment Metallic and glass sphere of same size released at a height
This is not what OP is asking about. The density can be anything. What will be different is the conductivity.

comment If photons don't have mass, how can they accelerate objects?
It does have everything to do with momentum. Light does not have charge or mass, but it does have momentum. en.wikipedia.org/wiki/Photon#Physical_properties

comment Is force the unique possible relation between particles?
Your answer is well written, and maybe well meant, but... I doubt that OP will able understand any of this. The OP question is all over the place - closer to creationism than physics.

comment How does a flywheel generate electricity at a constant voltage?
When you say the generator, what do you mean? A specific instance of a generator? -located where? Or maybe specific type of generator? Have you read the wiki page? en.wikipedia.org/wiki/Electric_generator

Not just twice as well, but more than twenty times better.

comment Is there a sound that explodes gunpowder?
@Jitter: No - it is not light, but microwaves - hence the name microwave oven. Microwaves and light are both electromagnetic waves.

comment Is there a sound that explodes gunpowder?
"Sometimes, microwave heating is explained as a resonance of water molecules, but this is incorrect;[14] such resonances occur only at above 1 terahertz (THz)." from en.wikipedia.org/wiki/Microwave_oven

comment During reflection does the emitted photon have same properties?
Depends on what you mean by similar. In both cases there is an incoming and outgoing photon and an electron(within an atom) involved. You can read about both processes on wikipedia.

comment During reflection does the emitted photon have same properties?
What you are describing is not reflection, but photoluminescence. What you want is called Compton scattering.

comment Does thermal energy change within a chamber depending on what's in it, where it is, what it is?
Nothing is wrong with cubic-feet and fahrenheit in everyday use in parts of the wold. You also write lb and ounce and 9x9 nothing. All of it seems irrelevant to what you are asking.

Does the weird numbers and units have any relevance for your question?

comment Death by neutrinos - polonium go home
Your argument is valid. Your calculations are very wrong. You can only add cross sections like that in the zero limit (I believe you know that).
