| Term | Definition |
| Kerr-Newman | rotate and have a charge |
| Schwarzschild | black holes do not rotate and have no charge |
| Black hole | is a region of space in which the gravitational field is so powerful that nothing, including light, can escape its pull. |
| Cygnus X-1 | the longest known black hole candidate |
| Black body | is an idealized object that absorbs all electromagnetic radiation that falls on it. |
| Thermodynamics | conversion of energy into work and heat and its relation to macroscopic variables such as temperature and pressure. |
| Statistical mechanics | which is concerned with the motion of particles or objects when subjected to a force. |
| Electromagnetic radiation | takes the form of self-propagating waves in a vacuum or in matter. |
| supernovae | it is creates black hole when a massive star undergoes it |
| statistical thermodynamics | This ability to make macroscopic predictions based on microscopic properties is the main advantage of statistical mechanics over classical thermodynamics. |
