  • Grossman features a radical new way of looking at quantum mechanics which suggests that even the multiverse will come to an end. A popular view of the multiverse says that the universe is just one of an ever-inflating multitude of discrete "bubble" universes. These bubbles are eternally budding off new universes even as individual universes age and die. But a new view of quantum effects--the brainchild of Sean Carroll at the California Institute of Technology and his colleagues--challenges this picture. It is also potentially very useful to quantum theorists, as it does away with some thorny issues that currently dog cosmology, including a particularly baffling paradox involving disembodied consciousnesses known as "Boltzmann brains."
