Then when all hydrogen gas is burned, fusion stops and the red giant collapses, forming a white duarf. When it is a white duarf, energy is lost and becomes dim turning into a black duarf. As a black duarf, it contracts and becomes more dense losing PEg. This is when it is a neutron star. The next stage is when the star goes super nova.
PEg needs to be released and an explosion takes place.
The last stage is when the star becomes a pulsar. A pulsar is intermitent pulses of radiation. This suggests that the universe did not always exist. Described as radiation left from the explosion suggested by the Big Bang Theory. This radiation when released by the Big Bang, moved in all directions equally.
