Example sentencesExamples - Even though both black holes and white holes are plausible scenarios according to general relativity, there is still a crucial difference.
- A white hole emits lots of light photons.
- It is still true that a black hole may in some way explode as a white hole, but we have no idea if it can, if it will, and if so, at what point this would happen.
- And just as Humphreys' model has the universe expanding out of a white hole (a black hole running in reverse) so too does their paper!
- The problem is with the amount of entropy in a white hole.
