Does it strike anyone else as odd that something as miniscule as the creation of a particle/antiparticle duo can happen in such a position in relation to the event horizon of a BH that one of the duo can be on either side of the event horizon? My understanding is that an event horizon is not that clearly defined.

Better have a word with them, Bill, they might not have thought of that grin

I wonder if we'll hear any more re this: "Physicists may have observed Hawking radiation for the first time" September 28, 2010

"Event horizons are not unique to black holes; they can be exhibited in a variety of physical systems, from flowing water to a moving “refractive index perturbation” (RIP) in a dielectric medium (in which light can change the medium's refractive index). It's this latter system that Belgiorno and his colleagues used in their experiment."
