- Black holes are generated when supermassive stars die. The gravitational collapse is so large that nothing escapes.
- When a star in a binary system becomes a blackhole it will slowly absorb the materials from its companion. These swirling materials will form an accretion disk around the black hole.

- 4. Black holes are theorized to form from (HS-ESS1-3) a. very massive planets that collide with very large stars, resulting in an excessive amount of matter This matter collapses onto itself, extinguishing the star and resulting in the black hole b. very massive stars when their core nuclear fuel has essentially expired, resulting in the core collapsing in on itself. This is due to gravitational forces that act without nuclear fusion counteracting them C. very small stars when their outer shell nuclear fuel expires, leaving the dense core to collapse in on itself. This results in massive gravitational forces d. very young stars that do not have enough nuclear fuel to start the massive chain reactions normally produced in stars emitting large amounts of electromagnetic energy 5. What evidence helps supports the idea of the Big Bang Thoery (HS-ESS1-2) a. Earth Soil Samples b. Neil DeGrass Tyson c. Apparent motion of planets d. Red shift of distant lightGravity waves produced by Black Hole mergers can be detected byWhat indicates that the gravitational wave originated from the merger of a black hole?
- What evidence can you cite that black holes really exist?What is the Schwarzschild radius? Group of answer choices The size of the radius for a mass where the escape velocity equals the speed of light. The radius light is bent to when passing a mass. The change in the perihelion of an orbit due to general relativity. The radius of the accretion disk around a black hole.8) Calculate the velocity of a galaxy with a redshift of 0.37.
