Mass is not a dead pile of stuff. It is energy wearing a quieter costume. E = mc² says a tiny amount of mass stores an enormous amount of energy — because c, the speed of light, is huge, and squared it becomes almost unimaginable.

Imagination is not the opposite of science. It is one of science's sharpest tools. Before the equation, there is a picture: an elevator falling, a beam that will not slow, a geometry that bends. If you cannot picture it, you may not yet understand it.
