SUMMARY

Experiments modeling black holes have demonstrated that a liquid passing through a lavel valve at supersonic speed can mimic the event horizon of a black hole for sound. At this point, sound waves can enter but cannot escape, analogous to the behavior of light near a black hole. Researchers are investigating signs of Hawking radiation, represented in this context by faint sounds emitted from the holes, with "phonons" and "virtual phonons" serving as analogs for photons and virtual photons. Understanding these concepts is crucial for grasping the implications of these experiments.

PREREQUISITES
  • Understanding of fluid dynamics, particularly supersonic flow
  • Familiarity with black hole physics and event horizons
  • Knowledge of quantum mechanics, specifically phonons and virtual particles
  • Basic principles of sound propagation in different media
NEXT STEPS
  • Research the concept of phonons and their role in quantum mechanics
  • Explore the principles of Hawking radiation and its implications in theoretical physics
  • Study fluid dynamics related to supersonic flow and its applications
  • Investigate experimental setups that model black hole phenomena in laboratory conditions
USEFUL FOR

Physicists, researchers in quantum mechanics, and students interested in astrophysics and experimental physics will benefit from this discussion.

I read about experiments that modeled black holes as a liquid passing through a lavel valve at supersonic speed, the point were the water went supersonic was like the event horizon of a black hole for sound - the sound could go in but not out. They were looking for sighns of Hawking radiation which in this case would be faint sound coming out of the holes. They said that "phonons" and "virtual phonons" would play the parts of photons and virtual photons. What is a phonon?
Thanks.

Try http://en.wikipedia.org/wiki/Phonon"
provides a good explanation relating to the speed of light through matter.
