Cruz is a dying star. A white dwarf heading for a blackhole. Thats physics. Its inevitable.
But Cruz is definitely dead politically. Deader than a box of doorknobs.
It’s an ad-libbed quote from the movie Tropic Thunder by the Character Les Grossman.
As well, theoretically a white dwarf could collapse into a neutron star if certain conditions are met. A neutron star in turn could collapse into a black hole if certain conditions are met.
If is unlikely, but possible.
