Contrary to popular belief
, modern cosmology
doesn't give the Big Bang
a specific location
. Instead, the Universe
expanded from a zero
size (if you believe in Relativity
) or from a size dependent on Planck's constant
(if you believe in Quantum Mechanics
). The precise analogy is that of a balloon inflating
, but imagine it starting from zero size. So all point
s originate at that singularity
, and the Big Bang
can be said to have happened at all points.
In particular, you get uniform background radiation of 3°K.
