A Black Hole is Born by Red-Shif

As the nuclear fuel is exhausted, the outward forces of radiation diminish, allowing the gravitation to compress the star inward. The contraction of the core causes its temperature to rise and allows remaining nuclear material to be used as fuel. The star is saved from further collapse, but only for a while.

Eventually, all possible nuclear fuel is used up and the core collapses. The star’s final mass and the remaining outward pressure that the burnt-up nuclear residue can muster determine how far it collapses, into what kind of object, and at what rate. If the star is sufficiently massive or compressible, it may collapse to a black hole. *

Let take a new look at the star’s compress.

When a photon is moving upward the star, its frequency shifts toward the red. Suppose a photon does form on the surface of star. Photon shifts to red. In during photon is leaving the star it loses its energy. So, the momentum of photon decreases.

The relationfiltered=dp/dt shows when momentum of photon changes, the strongly of gravity field cannot be stable.

In during that nuclear fuel of star is used, mass converts to energy and energy converts to gravitation force too. And the strongly of gravity force is increasing. It means the outward forces of radiation diminish and inward pressure of gravitational force multiples. Then star collapses and a black hole is born.

All of our ideas about the universe formed by our experiences on the earth. In the earth redshift and multiplying of gravity field is inconsiderable, but in a With Dwarf is considerable.
