That's the first moment in which we can describe our Universe as being full of matter-and-radiation, and stepping forward from that state given the known laws of physics enables us to explain how the cosmos took its modern shape. But it's all still expanding, forming new stars, and evolving. How will it end? Here's what science has to say.
