Static Black Holes Exert Pressure on Their Environment, Scientists Say

---

University of Sussex’s Professor Xavier Calmet and Ph.D. student Folkert Kuipers were perplexed by an extra figure that was presenting in equations that they were running on quantum gravitational corrections to the entropy of a Schwarzschild or static black hole.

During a discussion on this curious result, the realization that what they were seeing was behaving as a pressure dawned.

Following further calculations they confirmed their exciting finding that quantum gravity can lead to a pressure in Schwarzschild black holes.

“Our finding that Schwarzschild black holes have a pressure as well as a temperature is even more exciting given that it was a total surprise,” Professor Calmet said.
