The schwarszchild radius of an electron=1.353*10^57m, and to work out the volume of a particle assuming it is spherical is 4/3*pi*radius^3 so the volume of an electron at its schwarzchild radius is 4/3*pi*1.353*10^57^3 = 0!?!?!!! WHAT DOES THIS MEAN :S

I'd say it means you need to learn about operator precedence so that you don't confuse (10^57)^3 with 10^57^3 = 10^185193, causing an arithmetic underflow on your calculator.

May I suggest it's because the volume in cubic meters in less than 10^99, hence your calculator figures this is as good as zero. Fair enough wouldn't you say!

Electron schwarzchild radius problem
Anyways, applying the concept of Schwarzchild radius to an electron seems pointless.
EDIT: It appears it's not entirely pointless. There's even a wikipedia article about it.
