“These theories were based on the hypothesis that all the matter in the universe was created in one big bang at a particular time in the remote past.” -Fred Hoyle
It’s making headlines every time someone brings it up: a quantum calculation, a new theory or some mathematical evidence proves it once and for all: there was no Big Bang.

Is that even possible? Honestly, it depends on which definition of the Big Bang you’re using. As it turns out, there are two of them, and there’s a good (historical) reason for that. But in the context of what we know today, one of them isn’t a good definition anymore, and hasn’t been for decades.

Come find out what this all means, and whether it’s possible that the Big Bang never happened. (Hint: it did!)
