What exactly is spacetime? In this video, we explain spacetime in ridiculously simple words — from the X, Y, Z coordinates that locate you in space to the fourth dimension (time) that Einstein wove into a single continuum. Learn how Einstein's special theory of relativity (1905) showed that space and time are connected, how moving near the speed of light slows time down, how the general theory of relativity (1915) redefined gravity as the warping of spacetime, and why the trampoline analogy is both famous and oversimplified.
Whether you're a physics student, a sci-fi fan, or just curious about why gravity isn't really a "force" in Einstein's view, this beginner-friendly animated explainer covers it all.
