It's not a speed problem. It's a geometry problem.
Gravity isn't a force pulling light back. Mass bends spacetime, and light just follows the straightest path available, called a geodesic. Near a black hole, that bending becomes so extreme that at the event horizon, every possible path points inward.
Light doesn't slow down either. Locally, it always travels at c. The universe isn't breaking its own rules. The rules themselves are what make escape impossible.
Think of it like this: you can't outrun tomorrow, no matter how fast you move. Inside a black hole, "outward" is no longer a direction in space. It's like trying to go back in time.
This is why black holes aren't a flaw in physics. They're one of Einstein's most spectacular predictions, confirmed by gravitational waves and the first image of a black hole's shadow.

Spacetime. Whilst Hermann Minkowski and Albert Einstein originally formulated Spacetime as a geometric coordinate system, modern interpretations have increasingly treated it as a dynamic, physical substance. Originally, Einstein viewed spacetime NOT as a tangible, material ether, but SOLELY as a mathematical continuum—a metric framework necessary to chart field-values, thus, to predict the relativistic, (questionable), phenomena like time dilation and length contraction. For early relativity, Spacetime served as an abstract coordinate background to map the behaviour of REAL, physical entities; rather than acting as a physical entity itself. Over time, however, theoretical physics has allowed this CONCEPTUAL metric to acquire active, mechanical properties. Spacetime curvature is routinely described as if it exerts physical forces: pushing matter, carrying gravitational energy, expanding, and rippling in waves. Which, of course it can’t and doesn’t, as that creates a conceptual SHIFT where the metric used to measure a field is conflated with the physical field itself, attributing material agency to a geometric abstraction. This reification becomes particularly pronounced in explanations of relativistic paths, such as the decay of atmospheric muons. Relativistic models state that a particle's experienced time depends on its specific trajectory through spacetime curvature. Yet, attributing physical choice or geometric navigation to an inanimate particle traveling through empty space, blurs the line between abstract coordinate paths and physical causality. By treating Spacetime as a malleable material rather than an observational framework, modern physics is, disingenuously, turning a mathematical tool into an active physical agent.
