Where was the Big Bang located? In which constellation? Should we observe more young galaxies in that direction and more old ones in the opposite direction?

You've got the commonest misconception about the Big Bang: that it happened at some particular spot in preexisting empty space, like an exploding hand grenade with galaxies for shrapnel. Actually, the Big Bang gave birth not just to matter but to space itself. Space then expanded so the matter in space thinned out. In other words, the Big Bang happened right where you're sitting just as much as anywhere.
Here's the short, elevator-speech version: The Big Bang happened everywhere at once. And everywhere started small and grew big. Wrap your mind around that, and you've got it exactly.
