Einstein's general theory of relativity is conceptually quit
different from Newtown's theory of gravity ...this is problem 2-4

Given that virtually nothing can escape from black
holes, explain how black holes are important in producing the
enormous luminosities observed from the centers of some
galaxies.
Why are intermediate mass black holes so uncommon compared to
stellar mass and supermassive black holes? What techniques can
astronomers use to find them?
Which law of physics led Einstein to develop the Theory of
Relativity. :
Gravity is always attractive.
Motion is relative.
The speed of light is a constant.
The entropy of the universe always increases.
Einstein's Theory of General Relativity can be
considered a "good theory."
a) What did this theory explain that other theories
could also explain?
b) What did this theory explain that other theories
could not explain?
c) What did this theory predict that nobody had
expected, but which were found experimentally?
Which statement best describes the difference between special
relativity and general relativity?
a) Only the theory of general relativity includes gravity.
b) The theory of general relativity describes the behavior of
subatomic particles.
c) The theory of special relativity applies only to very massive
objects.
d) Only the theory of special relativity includes gravity.

At its weak limit, general relativity leads to
Newtonian gravity. Indicate to
minus three physical observations why this does not mean that
general relativity
is not more general than Newton's theory
