a massive light particle displaces its volume of space at the same speed.

If the universe consists of space structure then it must have a cause to make it move and spin at the same time

Space supposedly expands at a rate that is greater than the speed of light.

strictly speaking, "space" does not and cannot travel. If we are discussing the expansion of the universe (something that can be considered in terms of "volume", then yes, the distance between two points can increase faster than the nominal rate of light movement. One can imagine two "locations" in motion as volume expands, so each "moves" away form the other at the speed of light, causing the distance of separation to increase at double the speed of light. If you do that with an infinite number of points in infinite space, then the expansion can far exceed the rate that light travels.

This is not exactly a very precise way to look at things though, because the universe does not actually move. The things inside move, but not the universe. Expansion is not "movement".

Nothing can travel faster than light through empty space, but space itself can expand as fast as it likes.

Space is a void that has no beginning or end. It doesn't go anywhere and already contains the points of origin and destination.

Let us suppose that there is an "edge" to the universe and that it was expanding faster than the speed of light relative to us.

At some time "t" we observe where the edge of the universe is as far as the light reaching us indicates. Let us call this size S.

Now during the next interval or time dt the universe expands further and faster than light. It therefore takes MORE time than dt to reach us.

Let us imagine that the extra time taken for light to pass this difference is z and in that time the universe has expanded by x.

We would observe that the universe was at size S+ x at a time z BEFORE time t

ie we observe its size to be S at time t and size S+x at time t-z

which means its velocity as observed by us must be negative.

ie displacement / time = ((S+x)-S) / ((t-z) - t) = -x/t

We observe it to be shrinking. The OBSERVATION of the size of the universe then would be the same if it was expanding faster than the speed of light or if the universe was shrinking instead.

Which would lead to an interesting paradox.
