Why the universe shouldn't exist at all

“Why is there something, rather than nothing?” could be the oldest and deepest question in all of metaphysics. Long exclusively the province of philosophy, in recent years this question has become one that can be addressed by scientific methods. What’s more, a new scientific advance has made it more likely that we will finally be able to answer this cosmic conundrum. This is a big deal, because the simplest scientific answer to that question is “We shouldn’t exist at all.”
