Discreteness of Black Hole Microstates

Understand

It is explained that, for black holes much heavier than the Planck mass, black hole microstates can be well understood without string theory.

• It is essential to understand the antipodal identification at the horizon.
• We show why the microstates exhibit a discrete spectrum, and how they relate to the particles outside the hole.
• Version 2 has some minor typos corrected and a few sentences added for clarity.
