Abstract
We show that unstable D-branes play the role of ``D-sphalerons'' in string theory. Their existence implies that the configuration space of type-II string theory has a complicated homotopy structure, similar to that of an infinite grassmannian. In particular, the configuration space of type-IIA (-IIB) string theory on Bbb R10 has non-trivial homotopy groups πk for all k even (odd).
