Space and time were entirely separate. Theoretical physicist Sean Caroll explains how Albert Einstein overturned that idea. One of Einsten’s great insights was that space and time were related to each other, where you had space and you had time, Einsten says: actually, there’s only one thing which we call spacetime. And then he says: this spacetime thing, it’s not just the stage on which all the action plays out. It’s an act for itself. Spacetime can change, it can move, it can bend and it can warp.
Einstein’s theory of relativity states that spacetime is like a flexible fabric. The objects embedded in it: the Sun, planets, even us, warp that fabric.
