Way I see it is, the original point enlarged, namely its diameter increased and keeps doing so. At all tmes we are inside the original expanding point. I see all space and all things contained in the universe as not new but part of the original point, defrayed in new and varied terms. The space is created as is needed, simultainiously with any expansion. There is no space outside the universe - this would violate the finite factor.
