But I think it is earth-shattering to philosophical materialism, actually. With all due respect to all of you who have done the math - and note, I am very careful not to claim any knowledge about this matter which relies on having done that - I still say, that at this point in this thread, even taking into account all Krumple's arguments, which may be perfectly valid, for all I know, the question of whether an electron exists is still an open one.
We have already touched on the possibility discussed by many physicists that electrons pass in and out of existence. Is it too big a stretch to say that electrons really only have a
tendency to exist? It certainly seems true of what physicists call 'virtual particles' which are now an important part of the standard model.
One thing I think everyone looses sight of in all of this is the distance we have traversed from the original premise of Enlightenment materialism, namely, that the ontological basis of the universe is the atom. The atom, so conceived, really ceased to exist the moment it was shown to be composite. The whole idea of the atom is that it is ontologically primitive, eternal, and non-compounded. (I am speaking philosophy here, not physics.) Now we have a world picture, really unintelligible to anyone who does not have postgraduate degrees in mathematics, where 'nothing' contains immense amounts of energy, the fundamental unit of matter is called a 'particle zoo' (with at least SOME empty cages still in it) and matter and energy are convertable.
So as for philosophical materialism, so called, to quote the memorable line uttered by Private Hicks in Aliens, it's 'game over man', as far as I am concerned. We still cling to the hope that at least the fundamental nature of reality might be described by science and or mathematics, but many have long since abandoned any pretense of knowing what it
is.
