We haven't observed hawking radiation coming off of a black hole, but we have observed it in lab settings. https://iopscience.iop.org/article/10.1088/1367-2630

  I can't let this comment stand as it is. This is a "numerical observation", so a simulation. And not of a black hole, but of a model of a black hole in one dimension in a Bose-Einstein-Condensate. Nobody has created a black hole in a lab and measured its radiation.

    I specifically stated we have not seen it coming off of a black hole, but dismissing this as just a simulation is silly and reductionist. To do the same in a counter-argument, if I can accurately model fluid dynamics, I don't have to go drop a log in my bathtub to observe the effects. But sure, if you want, we can discount that specific study and focus on others that use different methods to detect it that aren't "just simulations" https://arxiv.org/abs/1009.4634 https://arxiv.org/abs/1009.4634 https://arxiv.org/abs/1401.6612 https://arxiv.org/abs/1401.6612
