Here is the riffwiki site concerning stellar metamorphosis on mathematical theory versus physics theory.
Physical Theory Versus Mathematical Theory
The consensus understanding of stellar evolution is currently based on mathematical theory and models. This is problematic because entities can be invented to explain certain phenomenon and be proven to exist based on faulty assumptions, thus meaning entities can be invented that do not have physical reality such as black hole singularities. According to consensus rooted in mathematical theory when a star dies it can collapse into a black hole singularity, but according to stellar metamorphosis stars undergo physical transformations and never become singularities. Physical theories based on direct observations do not require the addition of ad hoc hypothesis, therefore are much different than mathematical theories that can use false assumptions to prove the physical presence of non existent entities.
The 6, 7 and 8 numbered references are to Mr. Crother's papers. Black holes do not exist. A star does not collapse into a black hole at the end of its life, it collapses into a planet. Therefore we can realize that the star is the new planet and the planet is the collapsed star. This means they are actually one in the same, Earth is an ancient star, and the Sun is a baby Earth.
