  I discuss an experiment demonstrating nonlocality and conservation of energy
under the assumption that the decision of the outcome happens at detection. The
experiment does not require Bell's inequalities and is loophole-free. I further
argue that the local hidden variables assumed in Bell's theorem involve de
Broglie's "empty waves", and therefore "many worlds" achieves to reconcile
locality with the violation of Bell's inequalities. Accordingly, the discussed
experiment may be the first loophole-free demonstration of nonlocality.
