High Energy Theory Seminar

The extremal gravity proposal is a conjectured duality between pure gravity in three dimensions and a speculative set of 2d CFTS. I will discuss a computation of the number of black hole micro-states in these theories. This micro-state counting inspires a mild modification of the extremal gravity proposal which passes many non-trivial checks, and evades a no-go theorem of the original conjecture. I will further comment on the implications for more general sparse theories of gravity.
