The universe appears to be lopsided, and a new model that aims to explain this anomaly could offer a glimpse of what happened before the birth of it all. The model also intriguingly hints at what might have come before inflation, since it suggests that the universe's lopsidedness may be an aftereffect of a great fluctuation that occurred before inflation began. "It's no longer completely crazy to ask what happened before the Big Bang," Kamionkowski said. "All of that stuff is hidden by a veil, observationally. If our model holds up, we may have a chance to see beyond this veil."
