Take the 2-minute tour ×  After seeing this image:   And reading
this:  "The long wavelength limit is the size of the universe
itself, while it is thought that the short wavelength limit is
in the vicinity of the Planck length, although in principle the
spectrum is infinite and continuous."  The question is, how did
the EMS evolve? Was it weak at first, i.e. at Planck time, which
allowed certain reactions to modify, shape or add properties to
it?  What really defined the position and order of everything
that is the EMS? E.g. colors. What defined or added something as
colors to be inserted in that specific range of 400nm to 700nm.
Hope this is not to philosophical and thanks in advance.

human eye defined EM wave of wavelength 400–700nm as having
colors. –  KennyTM Dec 2 '10 at 19:30  2 Answers 2  I think
saying that the EMS evolved isn't really an accurate
description. The EMS simply
