WHY is there a cosmic speed limit?

Why is there a cosmic speed limit? It could even be why we're here

Nothing in the cosmos can travel faster than light speed. By distinguishing cause and effect and stopping everything happening in a jumbled mess, our existence depends on it

Coloured transmission electron micrograph (TEM) of chloroplasts from the yellow portion of a yellow/green variegated Coleus blumei plant. Chloroplasts are the sites of photosynthesis, the process that synthesises carbohydrates from carbon dioxide and water using sunlight. The structure of a variegated chloroplast is slightly different from that of a normal green chloroplast. The granal stacks, formed from parallel thylakoids (membranes, bright lines), that contain the chlorophyll pigments are less ordered in the variegated chloroplast. The pigments themselves are also slightly different. Magnification: x14,300 when printed at 10cm wide.

Beyond quantum physics: The search for a more fundamental theory

Quantum theory can’t be the final answer and some theorists are exploring new ways to formulate physical laws – and yet there is no guarantee that any theory can completely describe the universe
