Someone on another board asked something I’m not sure what the answer to is, so I’ll let some of you take a stab at it:

To paraphrase the question:

- matter can’t travel faster than light
- there was no matter/light/galaxies before the big bang
so how can we have all the matter for a Milky way galaxy get so far away from an ‘original’ galaxy’ in time for that matter to form the Milky way and earth in time for humans here to still see the light from that galaxy so near to the big bang?

Space got bigger.

It's far worse than that. Alan Guth's Inflation phase enlarged space so much that we see only 10^-9 of the actual universe radius inside the Hubble radius.

Because galaxies ‘ride’ on space. And space has expanded since the BB. The speed of light does not limit the speed of universal expansion.
