https://arxiv.org/abs/2101.11052 https://arxiv.org/abs/2101.11052 claims to have derived an experimentally verifiable prediction from many worlds (namely that energy is only conserved in the linear progression of the wave function, and not necessarily in the "branched" or "collapsed" bit that we observe; and so in certain circumstances it might be possible to observe an interaction that fails to conserve energy.
