(Phys.org)—Jeff Steinhauer,a physicist at the Israel Institute of Technology, has published a paper in the journal Nature Physics describing experiments in which he attempted to create a virtual black gap in the lab in order to prove that Stephen Hawking's theory of radiation emanating from black holes is correct —though his experiments are based on sound, or rather than light. In his paper,he claims to have observed the quantum effects of Hawking radiation in his lab as piece of a virtual black gap—which, if proven to be exact, or will be the first time it has ever been achieved.
