Black Holes - A Type of Dark Matter

A. accretion disk- spiraling gas and dust that spins around a black hole. Can be heated so intensely that it emits x-rays.event horizon- imaginary sphere around the black hole where all matter is crushed to a single point with infinite density.jets of gas- hot gas and energy released in a beam perpendicular to the accretion disk.

B. Gravity is directly proportional to mass, so with more mass comes more gravity.

C. If we are lucky, we could see the contrast between a black hole and bright object behind it. You could also see the jets of gas shooting out of black holes (Quasars).

D. The radius that needs to be breached in order for an object to become a black hole.

E. The space-time fabric described by einstein suggests an unending pit.
