Actually, this is only partly correct. There has been no "direct"
observation of it, but there has been indirect. But, technically, since
its so damn small, this would be correct. Mind, if you don't have it,
then you have to come up with something else to explain radiation from a
block hole, where there shouldn't be any, and that *has* been seen.

If its not particles, then what? Energy? Oh, wait, energy is still some
sort of particle, as near as we can come up with. Mind, it might not be,
if you go all the way down to String Theory, but that is just pure math,
it has yet to come up with math that correctly matches the observed
universe, and at best, *may* describe a near infinite list of "possible"
universes, of which ours is just one in gazzillions (which makes finding
the right math to match it, never mind verify that String Theory is
right, worse odds than winning the lotto).
In any case, no, the problem here is that you have to present a
plausible thing to "be" there, if you don't have particles, given that
even breaking up something like an electron gives you... more particles.
Again, its presupposing what is there, based on what needs to be, for
the math to come out right. It doesn't prove that the math *is* right,
in those conditions, or there is some basic limit, just like with
distance and travel, over time. There is simply the assumption that
there isn't one.
But, like I said, until he publishes, all we have is the assertion that
its not happening, combined with the embarrassing fact that certain
observations are not explained, by other means, without the prior
Hawking's Radition.
