I am of the opinion that gravitational accretion within the universe is impossible between EQUAL bodies in size. Yes, meteorites bombard Earth and comets Solar System bodies but otherwise their motions usually keep them from gravitational merger. For example, the rings around Jovian planets don't accrete- they just shift as if waves upon water.

Therefore, stars and planets don't form from small particles, nor do galaxies. Their formation process is instead one of masses splitting apart into sizable bodies which then absorb whatever loose matter is around them to become larger and then functional, as stars or planets, for example.

I reply to myself to further illustrate my theory. What I mean by "stellar reincarnation" is that Red Dwarves (small stars), White Dwarves (dead medium-sized ones), and Brown Dwarves (large planet-sized stars "unfusioned"). These would be attractors for loose matter around them which would then grow into the larger yellow and blue stars.

This would leave the question of what becomes of the heavy Neutron stars and Black Holes- do they also reincarnate into Bright Matter? According to evidence, they don't and only may become quasars, which have light shooting out of their poles in the form of electrons and positrons interacting with magnetic fields (I believe Hawkings explained how this happens).

I think the answer to the difference between Dark and Bright Matter is that mass may be either negative or positive because the former can only become more massive (and is therefore "dead") while the latter can acquire more mass, synthesize helium, and radiate light (and therefore is "alive").

As a universe ages, its positive mass gradually converts to negative and becomes locked back up into gravitational coffins until part of another Big Bang unless Dark Bodies collide in Space and their heavy elements are released as a result, such as gold, lead, uranium, etc.
