The fuzzball proposal for black holes: an elementary review

1,087 citations recorded by the source corpus.

We give an elementary review of black holes in string theory. We discuss BPS holes, the microscopic computation of entropy and the 'fuzzball' picture of the black hole interior suggested by microstates of the 2‐charge system.

• Four dimensional black hole microstates: from D-branes to spacetime foam (2006, background): “In this perspective most microstates should enjoy such a flow and the usual solution with a horizon is simply the effective long-wavelength description of many complex, spatially extended microscopic bound states [3, 4, 5, 6, 8, 9, 10, 11, 12].”
• Tests for the existence of black holes through gravitational wave echoes (2017, background): “holes, an example of which was discussed carefully in the context of “BH foils” [19]; fuzzballs [2, 3], were introduced as a microstate description of BHs in string theory.”
• Testing the rotational nature of the supermassive object M87* from the circularity and size of its first image (2019, background): “Motivations for relatively large values of Rss/M have been provided in terms of the BH information paradox [48– 50], which seems to require new physics appearing at the gravitational radius of a system rather than at the Planck scale [51–54].”
