Before Stephen Hawking came up with the concept of Hawking radiation, the question of black holes having entropy had been avoided. However, this concept demonstrates that black holes radiate energy, which conserves entropy and solves the incompatibility problems with the second law of thermodynamics. Entropy, however, implies heat and therefore temperature. The loss of energy also implies that black holes do not last forever, but rather evaporate or decay slowly.

WebNo, a 1kg mass would not turn into a black hole, even if it were zipping past you at very close to the speed of light. The principle of relativity is a fundamental idea in physics, and one consequence of it is that we can understand the physics of something that's moving by imagining we're moving alongside it. WebBlack holes increase in size thanks to the abundance of dust and matter surrounding them. Even “empty” space is not a true void and can still provide nourishment to these monsters. While Hawking’s theory states that a black hole could shrink, it would take a significant amount of time for the escaping radiation to have any significant effect.
