Imagine an astronaut falling into a black hole. Describe the effects that the astronaut would experience firsthand, and the changes that an external observer would see
What will be an ideal response?
The astronaut would notice that initially s/he would first fall slowly because the gravitational pull would not be very large. The longer the astronaut fell, the closer s/he approached the center, the higher the gravitational pull, and the faster s/he would travel until you reached the event horizon.
An observer outside of the black hole would notice something different—the effects of time dilation. They would see you fall more and more slowly as you approached the event horizon because time slows in a curved space-time.

Newton's Cradle consists of an aligned row of identical elastic balls suspended by strings so they barely touch one another. When two balls are raised from one end and released, they strike the row and two balls pop out from the other end
If instead, one ball popped out with twice the speed of the two, this would violate A) momentum conservation. B) energy conservation. C) both of these D) none of these
