That part I have no trouble with it's the size and scale I have trouble with.

I was thinking that as the compression increases the electrons would be pushed inward causing them to spin faster and faster until they could not hold orbit.

then they are released and cannot find any atom that will accept them.

so they burst outwards in the form of energy. (light?)

this allows the matter to fit into a smaller area.

this continues until the atoms really dont have any electrons as a shell.

there is an enormous space between the nucleus of an atom and its orbiting electrons.

this allows for a awesome amount of matter to fit into a softball sized area.

our moon perhaps !

the way I like to think of it is our solar system is an atom.

the distance from pluto ( was a planet in my day ) and our sun would be removed and only our sun would remain as a part of the compressed mass.

of course our suns mass would also release its energy and become extremely small.

3/4 inch of dust build up on the moon in 4.527 billion years,LOL and QM is fantasy science.
