Well you could have a virtual particle whose mass could be time-averaged.
replyNeutrinos weight far less than electrons (but while NAND flash involves super weird physics it's not that weird)
replyThey do weigh far less, but a quantity of "10^-15 electrons" is still impossible.
reply10^–15 is not a negative number, just a small one. https://www.wolframalpha.com/input?i=10%5E-15+
replyAnd it is less than one?
replyI think my favorite part of that comment is "documenting" that 10^(-15) is not negative by appealing to Wolfram Alpha.
