The silliest thing is to talk of<br />"the" multiverse theory when we are really tolking about several totally different physical scenarios. For example, one version simply relies on the universe being infinite while the visible universe is finite. Many physicists are certainly very interested in measuring the curvature and expansion rate of the universe, and are in this sense are very, very, "bothered" with the topic.<br /><br />Last month there was a conference in Vienna about Quantum foundations. There very few actual Many Worlders there, but Howard Weiseman presented yet _another_ model "Many Interacting Worlds". Here instead of slicing and dicing a giant wavefunction, they imagine a vast number of Bohmian trajectories and propose a (sort of) classical interaction between those trajectories which the guiding wave.
