Wave-generated 'white hole' boosts Hawking radiation theory: research

Wave-generated 'white hole' boosts Hawking radiation theory: research: Placing an airplane wing-shaped obstacle in the path of the flowing water created a region of high-velocity flow which blocked surface waves, generated downstream, from traveling upstream. The obstruction simulated a white hole, the temporal reverse of a black hole.
The shallow surface waves divided into pairs of deep-water waves, analogous to the photon pairs featured in Hawking's theory. Like in black holes, they showed that the analog would also emit a thermal spectrum of radiation.
