    I just got told something about acoustic black holes that mimic gravitational black holes and it made me very curious.

    What I have so far is that they can be formed in a liquid where some of it is moving faster than the speed of sound in the liquid.
    It was suggested that they should display a sonic form of Hawking radiation.

    I was wondering if anybody here knows much about them and would be willing to explain them a bit?
