  We construct wormhole-like solutions in the type IIA string theory. These
solutions represent wormholes in four-dimensions and are given by the D2 branes
within appropraited backgrounds fields. We present the conditions on these
fields which lead to the four-dimensional wormholes. In the special case we
show how the particular solution in the type IIA theory leads to the dynamic
wormhole. We also speculate about the number of universes and the cosmological
constant.
