"Where exactly did the Big Bang happen? Well, nowhere—and everywhere. As NASA's Michelle Thaller explains, thinking of the origins of our universe as an explosion with a central hub is misleading. "The Big Bang wasn't an explosion of matter, it was an expansion of space itself," she says. We don't know how big the universe is, but the general consensus is that there is no edge to the universe, and no center either."
