	I have a few simple thoughts (and keep your puns to yourself)
about the "problem" of creating energetic particles.
	1)  How does the highest energy particle that we can/will
<in the near future, that is> produce compare with the most highly
excited particles that come from Supernova, black hole accretion
cloud radiation, and other similar natural processes. (I'm not
claiming anything, I'm just asking for a comparision of the man made
processes and the more powerful natural ones.)
	2)  What would be the effect of a black hole, with its surrounding
discontinuities, etc, on the "false vacuum"?
	3)  What about Seyfert Galaxies, Quasars, etc??  

I'm not all that knowlegable about the various processes I've
named, but a comparison between the natural and man made energies would
be interesting.  
A related question is:
	Are cosmic rays the most energetic natural particles known, including
those from catastrophic sources???
	I must admit that the false vacuum idea seems to give a bit
too much credit to the abilities of mankind...
