Black Holes

4. one of the four main forces in the universe, most present in black holes
6. the process the results in the formation of a black hole from a star
7. energy that a black hole emits, causing it to eventually dissipate; discovered by a famous scientist who died on pi day :(
8. the distance from the center of a black hole to the edge
11. a theory that explains the gravitational effects on space-time
13. a variation of black hole that is assumes angular momentum
14. the process of an object stretching out as it falls into a black hole
15. scientist who developed the theory that explains the gravitational effects on space-time

1. the matter around a black hole
2. the edge of black hole
3. jets emitted from the poles of a supermassive black hole that extend for light years
5. a phenomena common with black hole mergers; they travel at the speed of light and are measured on earth
9. an infinitely dense point within a black hole
10. an upper mass limit of a neutron star before it becomes a black hole
12. the slowing passage of time as an object gets closer to a stronger gravitational force, mostly seen with black holes
