PHYSICISTS DREAM UP 'SPACETIME QUASICRYSTALS'.

The article focuses on the theoretical discovery of spacetime quasicrystals—structures that combine space and time in an orderly but non-repeating pattern, unlike traditional crystals or quasicrystals found in materials. These spacetime quasicrystals obey Lorentz symmetry, meaning they would appear the same to observers at rest or moving near light speed, a property not shared by known crystals. The researchers propose that such quasicrystals could underlie the fabric of the universe and have implications for quantum gravity and string theory, potentially explaining how extra dimensions might be compactified while preserving observable spacetime. Although the concept is currently theoretical and speculative, it offers a novel mathematical framework for understanding spacetime’s structure. [Extracted from the article]
