How do black holes work
Black holes are massive objects that have become so dense that they collapse in on themselves under their own gravitational attraction. The Schwarzschild radius \(R_{S}\) is defined as the distance from a spherically symmetric mass distribution at which the escape velocity from the sphere is equal to the speed of light, i.e., it is the location of the event horizon.

Such a tunnel would provide a shortcut between its end points. In analogy, consider an ant walking across a flat sheet of paper from point A to point B. The Event Horizon Telescope (EHT), a network of radio antennae around the globe, has captured the first image of a black hole event horizon.

Nothing - not even light - can escape. The study of black holes began in the 1930's, when an Indian astrophysicist named Subramanian Chandrasekhar found that there is a limit to how much gravity can be supported by matter as we know it. Nothing here on Earth comes close to exceeding this matter-gravity limit, but the phenomenon often occurs in ...A black hole is a region in space where the pulling force of gravity is so strong that light is not able to escape.

The simplest kind of black hole is a Schwarzschild black hole, which is a black hole with mass, but with no electric charge, and no spin.If the negative-energy particle were eaten, the black hole's mass would shrink by a tiny amount, and the object would emit a minuscule bit of radiation. Hawking worked out this idea in 1974, which ...A black hole is a massive object whose gravitational field is so intense that no light (electromagnetic radiation) can escape it.

When you launch a rock up into the air, it slows and is eventually pulled back down by gravity. If you launch it with more force, it starts off faster and goes higher before falling back to the Earth. If you continue throwing harder and harder, there will be a speed beyond which the rock escapes out of the Earth’s gravity.The concept of a “black hole” is one of the most curious in astrophysics.
