Before the Big Bang

ENCORE It’s one of the biggest questions you can ask: has the universe existed forever? The Big Bang is supposedly the moment it all began. But now scientists wonder if there isn’t an earlier chapter to our origin story. And maybe chapters before that! What happened before the Big Bang? It’s the ultimate prequel.

Plus – the Big Bang as scientific story: nail biter or snoozer?
