==========
Space: it's where things happen. Time: it's when things happen. We can measure where things are and when things take place, but in modern physics, we realize when and where are actually part of the same question. Because when it comes to understanding the universe, we need to replace three-dimensional space plus time with a single concept: four-dimensional space-time. We'll explore and explain space-time in this series of animations. Animations? Yeah. Well, we're not very animated are we? Sure we are! Look, I can go from here to here. Whoa! How'd you get from here to there? How fast did you go? Did you run? Walk? Did you even go in a straight line? Ah! To answer that, you'll need to make our cartoon physics look more like ...
