Do black holes have infinite density?

A maddening enigma called a singularity -- a region of infinite density -- lies at the heart of each black hole, according to general relativity, the modern theory of gravity. The infinite nature of singularities means that space and time as we know them cease to exist there. read more

Well, black holes aren't infinitely dense, and the singularities, which are predicted to have infinite density by current theories, are generally believed to be unphysical- artifacts of an incomplete theory- and thus not actually infinitely dense either. read more

(ISNS) -- The cores of black holes may not hold points of infinite density as currently thought, but portals to elsewhere in the universe, theoretical physicists say. A black hole possesses a gravitational field so powerful that not even light can escape. read more

A black hole is a celestial body of extreme density and high gravitational pull that not reflect or emit radiation. The process of forming a black hole is related to the evolution of some stars. As you know, a star of similar mass to the Sun ends up becoming a white dwarf, a small star with high density. read more
