The event horizon is the boundary in spacetime beyond which the gravitational pull becomes so strong that nothing, including light, can escape.

The singularity is the point at the center of a black hole where the matter is compressed to infinite density and gravity.

John Wheeler coined the term 'black hole' in 1967, although the concept had been theorized earlier by other physicists.

Spaghettification is the process by which matter and energy falling into a black hole are stretched and compressed due to the intense gravitational forces.

The singularity is the point at the center of a black hole where the laws of physics break down due to infinite density and gravity.

Hawking Radiation is the theoretical emission of particles from a black hole due to quantum effects near the event horizon.

Black Hole Merger is the process by which two or more black holes collide and combine to form a single, larger black hole.

A wormhole is a hypothetical tunnel or passageway connecting two different regions of spacetime, allowing for faster-than-light travel.

A quasar is an extremely luminous and energetic active galactic nucleus powered by a supermassive black hole at its center.

Black holes cannot be observed directly with telescopes due to their intense gravitational pull, which prevents light from escaping.

The Planck Length is the theoretical limit beyond which the laws of physics as we know them break down due to quantum gravity effects.

Black Hole Evaporation is the theoretical process by which a black hole's mass decreases over time due to the emission of Hawking Radiation.

The graviton is the hypothetical particle that is believed to be responsible for the gravitational force.

Intermediate Black Holes are not a recognized type of black hole. Black holes are typically classified as Stellar Black Holes, Supermassive Black Holes, or Primordial Black Holes.

A Black Hole Binary is a hypothetical system where two black holes orbit around each other.
