I'm not sure you are serious. You think a black hole is "nothing"?
Radioactive decay is "uncaused"? It is supposed that there are no physical laws governing nuclear bonds?
Uhm.. no.
In regards to the Hawking radiation... Okay, as the layman that is I simply understand it. The basic premise of/for a black hole is that gravity has collapsed to a point below (Beyond?) its Schwarzschild radius (Basically
anything if compressed enough can become a black hole).
So, in normal, regualr "Nothing to see here" space/time.... 'Things' (Elementary?) particles spontaniously come into existance. This is a feature (Bug?) of quantum particle physics. Yes, nature really does abhore a vacume
. Also, for reasons people a lot clever-er than I can expound upon, said particles always appear in pairs. This bit? I have no explanation about.
Now at the very edge. The very physical limit of the gravity abyss that is a black hole, this particles popping into existance out of nothing kind of hits a snag. While normally said quantum fluctuations 'vanish' again. Those that are lucky (?) enough to pop into existence at the boundary of a black hole find one particle effectivly on the 'Outsaide' of the event horizon and one half/particle on the inside.
SO, what happens then is that one particle vanishes inside the black hole and the other is now 'free' to go whizzing off into space.
WHat this means (I think) is that... should a black hole NOT be in the viscinity of anything else. Does not form/have an accretion disk of matter falling down into it THEN said black hole, via the quantum process that Hawking won great accolades for,
will effectivly evaporate away.
Note: The radiation is kind of governed by the surface area rule. SO a normal, large black hole will take more than the life time of the currently proposed reality to evaporate into nothing.
Also.... it won't just simply 'fade'. See, eventually that Schwarzschild radius? Yah... the gavity density on the 'inside' will fall below that threshold. When it does? Normal reality will then re-exert itself. Explosivly in effect.
Hope my poor layman's understanding and regugitation helps explain my point.
In the viscinity of the edge of a black hole. Elementary particles ARE, litterally, spontaniously, tottally unpredicably (As in, like Brownian motion "We can NOT predict, ever, where a quantum fluctuation might/will occur) coming into existence from
nothing.
Okay. Note that radio active decay is uncaused.
Pretty sure the physicists know what certain atoms just fall apart (Like Plutonium and Radium and such).
It has to do with, again, the nature of quantum stuff.
So. Uranum has a 'Half life'. After a certain amount of time, given that you start with 'X' amount of Uranium, you will only have half the amount of said uranium and... other stuff left. (Would have to Google-foo what the fall apart half turns into).
Now.... physicists can not, ever, tell you exacly 'When' the uranium effectily becomes reduced to 'Half'. Nor can they tell you exacly which bits of Uranium fall apart into the other stuff. Again, the whole quantum thing.
But Uranium definately does fall apart in such a manner and the particles deffinately do alchemically change in such an unpredictable way over time.
SO, as my point tried to explain and obviously poorly, when it come to things like atomic half life's (Am pretty sure there's more than just uranium that falls apart) the quantum nature meants that, in this instance, uranium spontaneously and
totally unpredicatably changes into something else over time.
But its doing so has no definite 'Cause'. We can't tell which particles are going to transmute. We can't tell when exacty the particles are going to transmute. But transmute they wiil AND at a kind of specific rate.
Again, I hope my layman's understanding at least partly comes across with my hamfisted explanation.
EDIT: Because Deesse23 is so awsome sauce.

We can give an average half life for each radiactive substance, based on empirical evidence and in accordance with the known laws of physics.
We can (not yet) tell which individual atom (of a given substance) will decay when. We currently can not determine a "cause" for radioactive decay of a single individual atom.
You didnt know this?
EDIT, EDIT: Also, my spelling does suck and I completely appologize for such.
Not at work.
