A black hole is an object that has collapsed under its own weight to a point, creating an object that is fantastically small, yet enormously dense. It sucks in everything it can absorb, and once ...
Protons get converted into neutrons, positrons and electron neutrinos. The neutrinos cause the outer layers of the star to explode as a supernova. The core becomes a neutron star. If the core is massive enough it overcomes the neutron degeneracy pressure and collapses into a black hole. The thirds type of black hole is the supermassive black … Formed from the condensation of raw materials in the early cosmos, primordial black holes emerged soon after the Big Bang. Most were extremely tiny, and while those with the lowest-mass have likely evaporated, primordial black holes with larger masses may still exist - though even those have remained undetected.
