Israeli scientists have recently devised a “sonic black hole;” any sound that passes its edge can never come out again. This is achieved by two clouds of atoms (called a Bose-Einstein condensate) cooled to almost absolute zero, with a pool of very low density between them. Atoms can flow very rapidly, pretty much unhindered, into this area of low density at speeds over four times the speed of sound.
