Black hole stars were potentially the largest stars that ever existed. They had up to 10 million solar masses and were 800,000 times larger than the sun. They were only possible in the early universe when the universe was denser and matter was concentrated in dark matter halos. The massive gravitational pull of the dark matter halos caused clouds of hydrogen to form, leading to the creation of extremely massive stars. In some cases, the star grew so massive that its core was crushed into a black hole. A tremendous explosion resulted, but the star still survived and had a black hole at its center. The black hole kept the angular momentum of the star and matter was drawn into an accretion disk where gas orbited the black hole at nearly the speed of light. Friction between particles in the accretion disk caused it to heat up to millions of degrees.
