Physicists dream up ‘spacetime quasicrystals’ that could underpin the universe

Physicists have theoretically discovered that quasicrystals—orderly structures without repeating patterns found in meteorites and atomic bomb debris—can exist in spacetime itself. Unlike regular quasicrystals that appear different to observers moving at high speeds, these spacetime quasicrystals maintain Lorentz symmetry, appearing identical whether viewed from rest or near light-speed motion. The researchers suggest these structures could underpin the universe's fundamental framework and offer new approaches to quantum gravity theories and string theory's extra dimensions.
