  We consider the possibility that physics beyond the standard model
contributes to the decays B -> V1 V2, where V1 and V2 are vector mesons. We
show that a time-dependent angular analysis of B -> V1 V2 decays provides many
tests for this new physics (NP). Furthermore, although one cannot solve for the
NP parameters, we show that this angular analysis allows one to put bounds on
these parameters. This can be useful in estimating the scale of NP, and can
tell us whether any NP found directly at future high-energy colliders can be
responsible for effects seen in B -> V1 V2 decays.
