consensus reality - have you ever seen an electron, I know I haven't. It seems that scientists are just as capable of believing in their invisible imaginary friends as deists are, lol.
I've found reference to research on 'wet electrons' that claim to have isolated electrons in a sort of limbo state, but still no piccie.
For something to exist - in any meaningful sense - it ought to at least have a shape and definable size.
Now that doesn't dismiss the usefulness and validity of the concept of an electron within physics and its function in the world, but, by the same token, the usefulness and validity of virtual particles would be no less valid. If it works, use it.
Re: size of an electron.
This looked promising until I realiseed who the author was.............lol.
