Black Holes ⚫

Black holes have solid surfaces

false

If density increases, gravity

increases

space-time

is warped by mass and causes orbits

• Curvature of spacetime due to mass

Objects of lower mass follow the warps made by more massive objects -> warps are gravity

behavior of light in a curved spacetime

light follows the curves

Gravitational lensing

the bending or "lensing" of light caused by the warp in space from massive objects

Escape velocity:

how fast you need to travel to no longer feel the force of gravity from an object

event horizon

the location around a black hole where the escape velocity equals the speed of light; the boundary of a black hole

Schwarzschild radius

the distance from the center to the event horizon in any black hole. How big the black hole is.

If you replaced the mass of the Sun with a black hole of equal mass, what would happen?

Nothing would change about the orbits of objects in the Solar System
