What is the speed of light that has been red-shifted
to a frequency of zero? to a negative frequency?

http://en.wikipedia.org/wiki/Relativ...Doppler_effect

"If the observer and the source are moving directly away from each other
with velocity v, the observed frequency fo, is different from the
frequency of the source fe, as

fo = sqrt{{1-v/c}/{1+v/c}}xfe

where c, is the speed of light."

From high school algebra, fo is always greater than zero.

Nonsensical question.
