- 5) A black hole in the center of a nearby Galaxy has a Schwarzchild radius of 2.0*10^7 km. How many times more massive than Sagittarius A* (~4*10^6 solar masses) is said black hole ?Name the chemicals leading to the formation of black hole.The first confirmed black hole, Cygnus X-1, was regarded as proof that black holes exist because ita. is a compact object in a binary systemb. emits X-rays from a hot accretion diskc. is accreting matter from a main-sequence companion d. has a period of 5.6 dayse. has a mass of ten solar masses
- What keeps a neutron star from collapsing into a black hole?Suppose black holes radiate their mass away and the lifetime of a black hole created by a supernova is about 1067 years. How does this lifetime compare with the accepted age of the universe? Is it surprising that we do not observe the predicted characteristic radiation?How would it appear to an outside observer if someone were to enter a black hole?
