Why the Speed of Light is NOT a Speed

What if the speed of light isn't really a speed at all? In 1905, Einstein proposed that light always travels at the same velocity, no matter how fast you chase it. But the deeper truth is far stranger. The constant we call c is not a property of light. It is the speed limit woven into the fabric of spacetime itself, a geometric boundary that no object, signal, or influence can ever cross. This documentary traces c from Einstein's original 1905 paper through Minkowski's revolutionary fusion of space and time, into the mathematics of spacetime intervals and light cones, and onward to gravitational waves, quantum entanglement, the redefinition of the metre, and the dimensionless constants that shape reality at every scale. Along the way, five apparent violations of the light speed limit are put to the test, and every single one of them confirms the deeper geometric truth.
