Hawking radiation from a sonic black hole had its temperature taken | Science News

If the end result holds up, it's going to affirm a prediction of cosmologist Stephen Hawking, who first proposed a stunning fact about black holes: They aren’t without a doubt black. instead, a notably small circulate of debris bleeds from every black hollow’s margin at a temperature that relies upon on how large the black hollow is. Such Hawking radiation is simply too faint to examine in genuine black holes. however physicists have noticed pointers of comparable radiation from analogs of black holes created inside the lab (SN: 12/18/10, p. 28). inside the new observe, the sonic black hollow’s temperature concurs with that predicted by way of Hawking’s idea, the group reviews within the may also 30 Nature.
