Nope. Numbers matter. Stars lose some mass, but it's not that fast. You appear to have invented an absurdly-large mass loss rate out of thin air. (Heck, dwarf stars lose mass much much more slowly than giants.)
Nope, totally wrong. A collision energy of "many MeV" will produce a fusion reaction in a very large fraction of collisions. Collision energies of a few keV (and thermal distributions around that) will produce nontrivial but nonzero fusion reaction rates. This is a simple laboratory fact; I've done fusion reactions in my own lab in 10 keV beams.
The actual laboratory data, including the actual numbers, says that the Sun's core temperature does correctly predict the Sun's fusion reaction rates and energy output. (And its neutrino output. And its neutrino spectrum. And its density and sound speed.)
You guessed that MeV energies were needed? Based on misreading something, I presume? You made a mistake and reached a wrong conclusion. What are you going to do about it?
Nope. Again, numbers matter. Radiative energy loss is slow (and we know how slow---do you?) A red dwarf star is expected (by the actual laws of physics) to maintain its core temperature, including a fully-ionized and convectively-mixed plasma with no core, for trillions of years.
I understand that you have a mental picture of a cold star with rocky material accumulating in the core, but you just made it up. It is not something that is allowed to happen, according to the actual properties of gases, plasma, radiation, chemicals, and ions. Your mental guesswork picture is inaccurate. What are you going to do about that?
It's easy to paint mental pictures. Since that is all you have ever done, of course you think it's easy. You skipped the hard part, i.e. using the laws of physics and chemistry accurately, and you got everything wrong. Real scientists, whose goal is to get things right, have to do the hard part.
This is gibberish. Activation energies are not some sort of immutable barriers. Chemical reactions proceed quickly in the presence of temperatures where kT exceeds the activation energy. You seem to think, erroneously, that they stop at lower temperatures? Or something? You think that there'd be no silicon dioxide on Earth if the parent silicon and oxygen atoms hadn't been baked together properly? Your idea does not correspond in any way I can identify with what I know about the chemical makeup of the Earth.
You did not explain how rocks form in outer space yet. Where is the activation energy required to form the chemical bonds needed to form rocks and minerals in outer space, absent pressure and heat?
Ignoring basic geology and chemistry will not suffice. Please get back to me when you can show how rocks/minerals form in vacuum absent heat.
