I agree with the theory of the "Bang" (but it's not proven) If the galaxies are moving away from us at tremendous speeds, are we also moving away from those galaxies, or are we in the "exact" center of where the Big Bang would have happened?

So, if we are also moving away from the galaxies that we see are moving away from us, it seems to make sense that there are other galaxies that won't be moving away from us, but we will be moving at the same "constant speed" as some galaxies...if I'm making sense, lol

The Big Bang literally happens everywhere. The expansion happens in such a way that it looks the same no matter which galaxy you are in.

Think of it this way: if a galaxy is moving away from me at 200 km/sec, then I am moving away from it at the same speed but in the opposite direction. There is no absolute measure of speed: only the speed of one thing with respect to another.

The nature of the expansion is like this: if galaxy A is twice as far away from me as galaxy B, then galaxy A is moving twice as fast away from me as galaxy B. But, it you work out the math, this will be the same picture for every galaxy! There is no center of the expansion!

(Imagine) you're stuck on the surface of (a) ball, with no real concept of up or down. The center of the ball isn't on the surface, it's inside, removed into the third dimension, which you cannot access. ...

The same can be said for our own 3-D universe. If it has a center, it might not be in our universe at all, but in some higher dimension. (p 149)

So, the universe (the Big Bang) could be centered somewhere in time (the 4th dimension) or simply not centered at all.

However, from a philosophical viewpoint, your answer is a good one. The Big Bang occurred here because all of creation is part of the Big Bang.

it happened everywhere. the name 'big bang' is slightly misleading - although it was not really understood at the time the theory first appeared, the big bang is now understood as an expansion of space, and the motions of galaxies away from each other are a continuation of the same trend. the fact that the cosmic background is the same in all directions supports this scenario.

There was no reference,at first,where the big bang started.
A single space-time pulse came into existence and expanded radially.
As it grew and matter emerged a reference to the matter and the origin was established.
The universe has a minimum size so it must also have a maximum size,this makes it finite and belies the accelerated expansion of the universe.
The farthest galaxies we see to be moving away from us don't exist now,they had reached their maximum distance as we will,one day.

The Big Bang occurred at the then center of the Universe.

we are not at the centre of universe.everything in the universe are receding eachother but not with the same speed.the further the object from earth the more receding speed they have.
when big bang happened 13.7 billion years ago there was nothing no time no space before that.big bang was the start of everything.if u have more reading on expansion of universe it would make more sense.tnx

" this thing had happened in space . about millions years ago."

The Big Bang was about 13 billion years ago and was a rapid expansion of space and time. Space and time started at the BB. It was not an expansion in space but an expansion of space. There is an excellent paper about the BB here:

We are also moving away from EVERYTHING else in the universe. Not at all in the center, however we are at the center of our "cosmic horizon". There is (undoubtedly) more out there than we can see because it is beyond our horizon.

supposedly everyplace in space is as equally away from the big bang as the other- I know its a weird concept

this thing had happened in space . about millions years ago.in this explosion every thing had scattered in space to far a distance . & to this time also our universe in increasing day by day. Galaxies & stars had created from this explosion
