Abstract
We find a new class of time-dependent brane solutions in supergravities in arbitrary dimensions . These are general intersecting light-like branes (null-branes), and their superposition and intersection rules are obtained. This is achieved by directly solving bosonic field equations for supergravity coupled to a dilaton and antisymmetric tensor fields. We discuss their possible significance.
