Multiverse Relativity

The extension of relativity to the multiverse, where not just space, time, probability, and initial conditions are relative to the observer, but the entire universe—or multiverse—is relative to the observer's position in the cosmic landscape. In multiverse relativity, different observers in different universes experience different physical laws, different constants, different realities entirely, and all are equally valid from their frames. This theory explains why our universe seems fine-tuned for life: we're in a universe where life is possible because we couldn't exist in the others. It's not that the universe was designed for us; it's that we're in the universe that fits us. Multiverse relativity is the physics of cosmic perspective: our universe is one among infinite, special only to us.

Example: "She contemplated multiverse relativity while stargazing: somewhere, in another universe, the stars were different colors, physics was different, life was different. Her universe, with its particular laws and constants, was just one slice of an infinite multiversal cake. She felt simultaneously insignificant (one universe among infinite) and precious (the only one she'd ever inhabit). The feeling was familiar: it was called being alive."
