Hi Luigi,and Double-A Why can't we think along with infinites? Why
must there be an end? Hydrogen atoms last trillion trillion trillion
trillion etc of years. What does a computer say about that? Where does
spacetime end? We read this in every book. It is stated in GR that the
universe began in a state of 'infinite" matter density,energy and
temperature. We have a dilemma in the quantum field
theory,for it predicts that certain quantities such as mass and charge
of the electron were "infinite" Hmmmm So along came Feynman and two
other guys,and they subtract out the "infinites" This is called
"renormalization" (I call it fudging) Feynman got his Nobel out of
this. However he claimed he did "hocus-pocus" math To be funny he
use to claim he got the Nobel for "sweeping some infinites under the
rug" Go figure Best to tell me where an EM wave comes
to an end?? If you can I'll believe only finite is in. Bert.
