It is eternal. Space has no size, shape or center. It has no inside or outside. It has not latitude nor longitude nor time. It is without limits in largeness and smallness.
Space is immovable.
When living things attempt to measure space it is done by comparing distance between objects that come within the scope of their own sight. If Space were enclosed then it would not extend everywhere. If Space extends everywhere and cannot be bounded, then it can have no size, for that without limits cannot be measured. If Space has no size and cannot be measured, then it can have no shape. If Space extends everywhere without limits and has no size or shape, then there can be no direction in Space.
