(Phys.org)—It was an intriguing week for physics as a pair of theorists suggested that their quantum equation predicts the universe has no beginning and thus there was no Big Bang. In their paper published in Physics Letters ...
University of California, Berkeley, scientists have proved a fundamental relationship between energy and time that sets a "quantum speed limit" on processes ranging from quantum computing and tunneling to optical switching.
