For me, the most counterintuitive thing is that the more energy you put in the colder the black hole becomes. Is there any other object that behaves that way?

- bonki 3y agoLots of human beings behave exactly like that...
- nh23423fefe 3y agotemperature is analogous to surface gravity which gets weaker at the event horizon as the black hole grows. temperature is not expectation of a kinetic energy distribution of micro constituents. you don't measure a black holes temperature with a thermometer because you can't get information out of a black hole
- ithkuil 3y agoDoesn't a black hole radiate hawking radiation and a smaller black hole radiate with a higher temperature than a bigger one?
- nh23423fefe 3y agoYup wikipedia agrees, temperature is inversely proportional to mass.
