Galaxies expand in different directions implying there is not one place in the universe where the expansion began
We have no idea where the centre of the universe it and therefore we can not answer this question. The universe is expanding in all directions and we can not tell one direction from another.
It happened in the center of the universe, for which it is still expanding on the universe.
According to current theories in cosmology the universe is expanding and it has no center.
The farther an object is from the earth, in any direction, the faster it is receding from us ... it looks just as if the earth is the center of the expansion. But wherever you are in the universe, that place would look to you as if it was the center of the expansion. The universe is already infinite, it has no boundary, but it's expanding. Are we confused yet ?
No it does not. It is my basic understanding of this theory that the 'true center' of the universe would be mostly devoid of material.
Other galaxies are moving away because the universe is expanding, but we are not at the centre of the universe.
Wherever you are located, it seems as if you are at the center of the expansion.
Aristotle's model of the universe took into account the charted movements of the heavenly bodies, but was complicated by the assumption that Earth lay at the center of the universe.

Our universe is expanding constantly so there is nothing anywhere that is stopped.
This is unknown. It is believed the universe is expanding but what we actually know about things outside of our own galaxy, or even our own solar system, is very limited. If it is expanding, than the center would be ever changing unless it is expanding in complete uniformity. Although it may be infinite so there would be no center.
NO ... it is the center of our solar system. That is, all our local planets revolve around it. Our solar system revolves around the center of the galaxy, about once every 220 million years. As for the universe itself, it has no center. Imagine the surface of a soap bubble. Where is its center? The surface HAS no center, as our universe may be geometrically represented by the surface of an expanding sphere.
