Black hole candidates are conspicuous by their continuous or flickering emission of   a. infrared light.   b. ultraviolet light.   c. gamma rays.   d. X rays.   e. all of the above.
What indicates that the gravitational wave originated from the merger of a black hole?
Use the Schwarzchild formula, Rs = 2GM/c2 , where Rs = Radius of the star, in meters, that would cause it to become a black hole M = Mass of the star, in kilograms, G = A constant, called the gravitational constant = 6.7 * 10-11m3/kg .s2, c = Speed of light = 3 * 108 meters per second. to determine to what length the radius of the Sun must be reduced for it to become a black hole. The Sun’s mass is approximately 2 * 1030 kilograms ?
