What boundary surrounds the singularity in a Black Hole from which nothing escapes?
Answer
The event horizon.
A black hole forms when the remnant core mass exceeds the Tolman-Oppenheimer-Volkoff (TOV) limit, causing gravitational collapse to continue relentlessly until all matter is compressed into a single point of infinite density known as a singularity. Surrounding this singularity is a critical boundary in spacetime defined as the event horizon. This boundary marks the point of no return; the gravitational pull exerted at this specific distance is so overwhelming that absolutely nothing, including electromagnetic radiation such as light, possesses sufficient velocity to escape its influence, rendering the object invisible directly.
