The Future of the Universe

Einstein's theory tells us that there is a given thing, which is the fabric of the universe. It's called space time and it doesn't tell you where it came from. But it does tell you how that thing stretches and warps and deforms in response to the matter and energy that are present in the universe. And we can say with some confidence that unless there's new physics that we don't understand, the universe is accelerating in its expansion.
