If each point of spacetime is associated with one and only one force direction (vector) then the concept of space expansion can be justified. A point is actually surrounded by an infinite number of points if spacetime is defined as a continuum. But how could infinite points be equally distant from a given point or for that matter, how can all points be equally distant from each other? If a spherical surface is considered as a continuum of infinite number of points then the center is equidistant from all these infinite points. But this topology isolates the center from the next layer of the gapping spherical shells. As continua, these shells are each composed of infinite number of points. Points between two shells are all forever disconnected from points between one other shell not sharing the same gap.

I think that each space-time point has an infinite number of directions and of combinations of directions at the same chronon, sort of the smallest quanta of time.

initially, yes. But once a direction is chosen, the point keeps this direction forever.

lol. I, guille, am Profet. Actually it's a very long story not important. I wrote that message. Just forget that and believe it was me.

Now, what makes the "choice"? For me, choice is a human invention and what defines that we have inteligence. Notihng else can choose.

each vector quantity has a given direction and a constant change of direction is technically called acceleration. A photon has a given constant direction and the magnitude of this direction is the speed of light.
