Could the Big Bang be Wrong?

This question comes up all the time in public forums and on social media. In most cases, it seems rooted not so much in misgivings about the science as in misunderstanding of what the science is. Any meaningful answer therefore has to begin with a crucial piece of clarification: The Big Bang means two quite different things depending on who you are talking to.
In popular conversation, the Big Bang is often used broadly to mean the mysterious primal event that created the universe, and it commonly envisioned as a tremendous explosion emanating from a single point. (To be fair, popular articles and illustrations often reinforce those ideas with oversimplification and confusing language.) But that is not what cosmologists mean by the Big Bang.
One key point is that the Big Bang was not an explosion of the kind any person has ever witnessed. ?This is a hard concept for people to get their heads around,? says Wendy Freedman, a veteran cosmologist at the University of Chicago. ?The first thing to get rid of is an image analogous to a bomb?which is our first tendency to imagine, and which is wrong?where you have an explosion with matter that flies outward from a center. This is not what happens in space. The Big Bang is an explosion of space, and not intospace. There is no center or edge to the explosion.?
