Electron schwarzchild radius problem

  1. Oct 30, 2010 #1
    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!

    Anyways, applying the concept of Schwarzchild radius to an electron seems pointless.

    EDIT: It appears it's not entirely pointless. There's even http://en.wikipedia.org/wiki/Black_hole_electron" [Broken]
