Understanding Black Holes

These flashcards cover key concepts related to black holes, event horizons, and theoretical physics.

Black Hole

A region in space where the gravitational pull is so strong that nothing, not even light, can escape from it.

Event Horizon

The boundary around a black hole beyond which no light or information can escape.

Density

The mass of a substance per unit volume; in black holes, it is theorized to be infinite.

Gravity

A force that attracts two bodies toward each other; becomes extremely strong near a black hole.

Core of the Black Hole

The central point of a black hole, theorized to be smaller than a fundamental particle.

Theories about Black Holes

Hypotheses regarding the fate of matter inside black holes, including possibilities of time travel or new states of matter.

State of Matter

A distinct form that different phases of matter take on; may differ inside a black hole.
