The common but powerful metaphor, sometimes extended to a mathematical model, treating spacetime as a flexible, elastic fabric (a manifold) that can be stretched, compressed, and curved by mass and energy. "Fabric" here is not a material, but a continuous geometric entity whose curvature dictates the motion of objects within it. It’s the standard visualization of General Relativity, made iconic by the image of a bowling ball on a rubber sheet.
Example: "She explained black holes using Relativistic Fabric Theory: 'Imagine spacetime as a stretchy trampoline. A star is a heavy rock. A black hole is when you push the rock so hard it pokes a hole through the trampoline. Things can fall in, but nothing, not even the trampoline's fabric (information), can climb back out.'"
