canadian_right informs us that scientists from Caltech have found hints of a time before the Big Bang while studying the cosmic microwave background. Not only does the study hint at something pre-existing our universe, the researchers also postulate that everything we see was created as a bubble pinched off from a previously existing universe. This conjecture turns out to shed light on the mystery of the arrow of time. Quoting the BBC's account: "Their model suggests that new universes could be created spontaneously from apparently empty space. From inside the parent universe, the event would be surprisingly unspectacular. Describing the team's work at a meeting of the American Astronomical Society (AAS) in St Louis, Missouri, co-author Professor Sean Carroll explained that 'a universe could form inside this room and we'd never know.'"
