Speed of Light

Before Einstein, time was the stage; after him, it became a player. He showed that space and time are fused into 'spacetime.' Gravity is not a force, but the curvature of this fabric. Massive objects bend time around them. A clock on a satellite ticks faster than a clock on Earth. Time is not a rigid ruler; it is a rubber band, stretched by mass and motion.

Why is there a speed limit? Without it, cause and effect could happen simultaneously, or in reverse. c protects the order of events. It ensures that the effect cannot precede the cause. It is the structural girder that keeps the narrative of the universe from collapsing into chaos.
