Experiments that modeled blackholes

[daniel_i_l]

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.

A phonon is a quantum of energy associated with the vibrational motion of atoms in a solid. In this context, it refers to the sound waves that propagate through the liquid in the experiment. Just like photons are the fundamental units of light, phonons are the fundamental units of sound. In the experiment, they are being used to simulate the behavior of particles near a black hole's event horizon. This is an interesting approach and could potentially provide valuable insights into the behavior of black holes. However, it is important to note that while this experiment may model some aspects of black holes, it is not a direct representation of the complex physics involved in actual black holes. Further research and experimentation will be needed to fully understand and model the behavior of these enigmatic objects.
