Cosmic Light Horizon
In
astronomy
, the
cosmic light horizon
is a "
horizon
" which marks the edge of the
visible universe
. This horizon is the edge of a
sphere
, centered upon the
Earth
, which is approximately 13.7 billion
light years
in
radius
; this figure is sometimes referred to as the "
lookback distance
" (because
astronomers
, who view distant objects, are "looking back" into the
history
of the
universe
-- see:
speed of light
). The general homogeneity of
temperatures
, at the edge of the
cosmic horizon
, is part of the
evidence
for the "
Big Bang
". See also:
