If spatial points exist, then they must be stationary, by definition [Le Poidevin]
|
|
Full Idea:
If there are such things as points in space, independently of any other object, then these points are by definition stationary (since to be stationary is to stay in the same place, and a point is a place).

A reaction:
So what happens if the whole universe moves ten metres to the left? Is the universe defined by the objects in it (which vary), or by the space that contains them? Why can't a location move, even if that is by definition undetectable?

For relationists moving an object beyond the edge of space creates new space [Le Poidevin]
|
|
Full Idea:
For the relationist, if Archytas goes to the edge of space and extends his arm, he is creating a new spatial relation between objects, and thus extending space, which is, after all, just the collection of thos relations.

A reaction:
The obvious point is what are you moving your arm into? And how can some movements be in space, while others create new space? It's a bad theory.

We distinguish time from space, because it passes, and it has a unique present moment [Le Poidevin]
|
|
Full Idea:
The most characteristic features of time, which distinguish it from space, are the fact that time passes, and the fact that the present is in some sense unique

A reaction:
The B-series view tries to avoid passing time and present moments. I suspect that modern proponents of the B-series mainly want to unifying their view of time with Einstein's, to give us a scientific space-time.
