A thermal spectrum of quantum noise radiation from black hole horizons was the surprizing prediction of Hawking’s 1974 calculation. Such thermal radiation is also predicted from other horizons. At UBC , we have carried out an experiment for surface waves in water at the white hole (time reverse of a black hole) analog horizon and have shown experimentally that the analog of the black hole horizon for such surface waves would also produce quantum noise with a thermal spectrum, increasing our faith in the robust nature of Hawking’s prediction.
