The dominant view in physics is simple: the laws of nature are fixed. Gravity pulls as it always has; quantum probabilities collapse with the same stubborn indifference today as billions of years ago.

Isaac Newton would never have discovered the laws of motion had he studied only cats. Suppose you hold a cat, stomach up, and drop it from a second-story window. If a cat is simply a mechanical system ...

The idea of emergent gravity is still new and requires a lot of assumptions in its calculations to make it work. But if experimental evidence ever proves it real, we would need to totally rewrite the ...
