Across
- 5. Black holes with a mass over 100,000 solar masses
- 6. Where matter is compressed into an infinitely tiny point
- 9. Collapsed core of a massive supergiant star
- 10. 1.4 solar masses, the theoretical maximum mass of a white dwarf
- 12. Spherical outer boundary of a black hole
- 13. Minimum speed needed for a non-propelled object to escape from the gravitational influence of a body
Down
- 1. Black holes emit matter and radiation, discovered through quantum mechanics
- 2. Stretching effect caused by extremely strong gravity, like in a black hole
- 3. Star between 10 and 25 solar masses
- 4. Massive celestial objects emitting very large amounts of energy
- 7. Rotating disk of matter formed around a black hole
- 8. Region of space where gravity is so strong that nothing can escape, including light or waves
- 10. Neutron stars are hot when they form and ---- slowly
- 11. Subatomic particle with a mass slightly greater than a proton
