The Menace of the Rolling Tachyon
Jim Cline
McGill University
If brane-antibrane collisions were the origin of inflation, the universe is
typically dominated by an exotic form of dark matter which is a rolling
tachyon condensate. I will review this picture and an attempt to solve the
problem by converting the tachyon energy into radiation. I will also discuss
some technical difficulties which occur when inhomogeneities in the tachyon
fluid are present.
