Testing for many worlds
Some interesting news from the physics arXiv blog: Frank Tipler has suggested a simple experiment to distinguish between the many-worlds and the Copenhagen interpretations of quantum mechanics. He argues that the interference pattern created when photons are fired one by one at a simple double slit should form more quickly if the many-worlds interpretation is correct. If his reasoning is correct, one of the most intractable problems of twentieth-century physics could soon have a clear answer.
