OBJECTION!

would not the fact that blue shifted galaxies being rare, mean that in general all galaxies are red shifted from the perspective of all galaxies, thus they are expanding away from a point on a similar vector, and thus have a central point?

No, it means the opposite. They are expanding away from all points, because space itself is expanding. In fact, stars are able to move away from each other faster than the speed of light, which is only possible because space is expanding. Again, like the surface of a balloon, we can imagine that the further away two points are from each other, the faster they’ll move away from each other as the balloon expands, so even if there’s a certain maximum speed that you can move along the surface of the balloon, if two points are far enough away from each other the rate that distance is created between them can exceed that speed.

If there was a single, specific point in space where all the stuff came from, then we wouldn’t observe the same thing in every direction. Sure, we might see stuff ahead of us redshifted because it’s moving faster and stuff behind us redshifted because we’re moving faster, but we should also expect to see stuff to the sides moving alongside us at similar speeds that would not be redshifted. The fact that there’s consistent red shifting in every direction, getting more pronounced the greater the distance, leads us to the conclusion that space is expanding.

And a balloon does have a vector of direction: the mouth piece

It’s an analogy, don’t take it too literally.

Imagine the universe as the surface of a balloon. The Big Bang Theory stipulates that at one point, the balloon was extremely small, like a single point. But now that the balloon is bigger, you can’t find a particular spot on the balloon where that point was, because everywhere was that point. No matter where you are in the universe, if you turned back time and shrunk the balloon back down, you would be at the point of the Big Bang. Nowhere is closer or farther away from it.

There’s a term for people who want to support the working class against the ruling class and it’s “the left.”
