State a necessary condition for a system to be chaotic.
Short Answer
It is considered to be chaotic if states that differ by a little amount in the starting circumstances diverge as the system evolves.

Get started for freeSupermassive black holes are thought to exist at the center of many galaxies. (a) What is the radius of such an object if it has a mass of\({\rm{1}}{{\rm{0}}^{\rm{9}}}\)Suns? (b) What is this radius in light years?
Quantum gravity, if developed, would be an improvement on both general relativity and quantum mechanics, but more mathematically difficult. Under what circumstances would it be necessary to use quantum gravity? Similarly, under what circumstances could general relativity be used? When could special relativity, quantum mechanics, or classical physics be used?
Question: If the universe is infinite, does it have a center? Discuss.
Andromeda galaxy is the closest large galaxy and is visible to the naked eye. Estimate its brightness relative to the Sun, assuming it has luminosity\({\rm{1}}{{\rm{0}}^{{\rm{12}}}}\)times that of the Sun and lies\({\rm{2 Mly}}\)away.
(a) A particle and its antiparticle are at rest relative to an observer and annihilate (completely destroying both masses), creating two\({\rm{\gamma }}\)rays of equal energy. What is the characteristic\({\rm{\gamma }}\)-ray energy you would look for if searching for evidence of proton-antiproton annihilation? (The fact that such radiation is rarely observed is evidence that there is very little antimatter in the universe.) (b) How does this compare with the\({\rm{0}}{\rm{.511 MeV}}\)energy associated with electron-positron annihilation?
