The Differential #6

Noise forms along a crystal edge; points delineate the surface in a thousand clustered moments, each one its polar opposite, joined and viewed from a distance by separate, sylph-like fragments of an instant's slow tick.

At the event horizon, the escape velocity is equal to the speed of light. Since general relativity states that nothing can travel faster than the speed of light, nothing inside the event horizon can ever cross the boundary and escape beyond it, including light.
