CRC

The Center for Relativity and Cosmology at Troy University focuses on work in mathematical relativity, relativistic astrophysics, and the interface between gravitation and quantum field theory. The center brings together faculty whose research spans analytical, geometric, and physical aspects of spacetime, black holes, and related phenomena.
