Black Holes

Study the formation and properties of black holes.

Sample Cards

Black Hole

A region of space where gravity is so strong that not even light can escape.

Event Horizon

The boundary around a black hole beyond which nothing can escape.

Singularity

The point at the center of a black hole where matter is infinitely dense.

Stellar Black Hole

The type of black hole formed from the collapse of a massive star.

Black Hole Merger

The process by which black holes can merge and grow larger.

Supermassive Black Holes

Large black holes found in the center of certain galaxies.

Hawking Radiation

Theoretical prediction of particle emission by black holes, proposed by physicist Stephen Hawking.

Time Dilation

The effect of black holes on time and space, where time slows down near the event horizon.
