The current paper issue of New Scientist must have been published too late to report Hawking's death.

But Rachel's words resonate with a report in the cover story about an experiment designed to "test one of the most famous predictions about black holes: that their edge or event horizon, glows with so-called Hawking radiation. Steinhauer blasted his fluid analogue with a laser to create something similar to an event horizon. Sure enough, he observed spontaneous sound fluctuations that mirror the ghostly Hawking radiation". (NS, 17 March 2018, "The Big Boil").

Could Rachel go on to explain in a bit more detail how this result corroborates Hawking's prediction?
