Science scratches its' head

The reason that we appear to be at the center of the universe from a visual standpoint is because the light that reaches us at this particular point in space from the edge of the universe is going to make a near perfect sphere with us at the center. However the same is true for any point in space, so the idea of being at the center is relative.

Hubble said the universe was expanding in all directions, with points farthest away moving fastest. So, if this is true, is there not a center of the universe, a starting point?

No it does not. Take for example two concentric circles, one being half the radius of the other, lets say respectively 1 meter and 2 meters. You are in the center. Both expand to twice their radius (to represent the expansion of a plane that these circles are attached to) over the course of 1 second.

The edge of the smaller circle moved away from you at 1 meter per second.

The edge of the larger circle would have moved away from you at 2 meters per second.

This aligns with what Hubble observed and works for any point on this plane, its mathematically proven. Again there needs be no center, even if this plane began from a single point.

How do we know if there's a center if we don't know the other edges.
