Quotes and Quips
To start this exploration, let’s first look at gravity. Gravity is not a force. It is not objects pulling on each other across empty space. It is not even—despite the famous analogy—heavy things making dips in a cosmic trampoline that other things roll into. All of these images, while compelling, miss what relativity actually reveals: that gravity is not primarily bent space, it is mostly bent time. This is not a metaphor. Clocks closer to Earth tick measurably slower than those farther away—GPS satellites constantly correct for this drift to stay accurate.
