This is commonly explained as evidence *for* there having
been a big bang. If an explosion occurs, then each of the
chunks sees all other chunks receding at a speed that's
proportional to the distance.
Astronomers rely on red-shift as their way of estimating the distances
of distant (far outside our galaxy) objects, because they now assume
that there was a big bang.
Question:
What is the most distant object whose distance was measured *other*
than by red-shift?
