Edited sentence: Fuzzball theory replaces the singularity at the heart of a black hole by positing that the entire region within the black hole’s[event horizon is actually a ball of strings, which are advanced as the ultimate building blocks of matter and energy.Fuzzballs are theorized by some superstring theory scientists to be the true quantum description of black holes.Modern physics breaks down when such parameters are infinite and zero.Strings are thought to be bundles of energy vibrating in complex ways in both the three physical dimensions of space as well as in compact directions—extra dimensions interwoven in the quantum foam (also known as spacetime foam).The information paradox wherein the quantum information bound in infalling matter and energy entirely disappears into a singularity; that is, the black hole would undergo zero physical change in its composition regardless of the nature of what fell into it.The singularity at the heart of the black hole, where conventional black hole theory says there is infinite spacetime curvature due to an infinitely intense gravitational field from a region of zero volume.The theory resolves two intractable problems that classic black holes pose for modern physics:
