That is not the claim I addressed. He said Hawking radiation has not been observed. I provided citations that it had.

- roywiggins 7y agoIt's been observed in the same way that magnetic monopoles have been observed: physical analogs have been built, but nobody has observed an actual magnetic monopole. "Nobody has observed a magnetic monopole" is still true, even if systems that behave like quasi-monopoles have been built. My conclusion (that we can't know for sure that black holes produce Hawking radiation) only makes sense if I was talking about observing actual Hawking radiation rather than analogs, which I was.
- causality0 7y agoThe claim that black holes are perfectly black is subject to those same constraints.
- Ma8ee 7y agoNo, it hasn't. Not in the real world. They have observed Hawking radiation in simulation (in an analog computer with some quantum properties).
