Understanding the microscopic structure of black holes has been a central goal in string theory. While significant progress has been made for supersymmetric solutions, a key question remains: what is the microstructure of the Schwarzschild black hole, the simplest solution in General Relativity? In this talk, we will introduce a new approach to account for the entropy of the Schwarzschild black hole through branes and antibranes in string theory. We will explore recent progress in constructing Schwarzschild microstates in supergravity, which appear as smooth, horizonless geometries that deviate from the Schwarzschild black hole in the near-horizon region.
