As others have pointed out, it is misleading to assume that the Big Bang occurred somewhere, because this implies that the ‘somewhere’ existed within (or distant from) something else, say 200 zillion miles from XYZ. At TBB, there was no space for it to happen 'within' – TBB created the space – and no time (which is why 'what happened before TBB' is a loaded question because when time does not 'elapse'*, the notion of 'before' loses its everyday meaning).

* - in the sense that a series of events, with some occurring before others, gives the impression of time 'elapsing'

Presumably this is why the cosmic microwave background radiation (often described as the afterglow of TBB) is *almost the same temperature in any direction.

*The ‘almost’ also generating a lot of excitement.

I find this stuff very interesting and would recommend several of the Fermilab videos on Youtube by Dr Jon Lincoln.

They are very watchable and there are several more.

Tallies to around 1.8 million mph, about 0.27% the speed of light.

Only if everything is moving in the same direction surely?
