For those who don't know:

This short explains about speed of light, black hole and singularity. The speed of light, around 300,000 km/s in a vacuum, is the fastest speed possible and serves as a fundamental constant in physics, crucial for equations like E = mc² This means it remains the same for all observers, regardless of their relative motion. Black holes are formed when massive stars collapse; they are regions with gravity so intense that not even light can escape their "event horizon." At the center of a black hole is a singularity, a point of infinite density and gravitational pull where space and time are stretched to their limits. This singularity goes beyond current physics, as the known laws break down in such extreme conditions. It is also a point of infinite density and infinitesimal volume. The immense gravity of the singularity causes extreme curvature of spacetime. Space and time themselves become distorted and cease to have meaning as we understand them. The singularity represents a limit of our current knowledge. To fully understand what happens at this point, we may need a theory of "quantum gravity" that can reconcile the laws of gravity (Einstein's theory of general relativity) with the laws of the very small (quantum mechanics).
