Abstract
We obtain a four-dimensional exploding universe solution in string the
ory. The solution is obtained from the string theory in the flat backg
round by using non-Abelian T-duality and the analytic continuation. In
the solution, the radius of the universe is finite for fixed time and
the universe is surrounded by the boundary consists of singularity Th
e boundary runs away with the speed of light and the flat space-time i
s left behind.
