Well, if space/time pre-existed then it would tend to "fill up." But it doesn't pre-exist. Space/time is created as the universe expands.

There are two worldviews though. One believes that space/time expansion is the effect of energy/matter. The other believes and energy/matter is the effect of the expansion of space/time.

I'm of the latter worldview.

Not me.. I believe UNdesignated energy/matter is Dark energy/ matter.. and designated energy/matter(this visible Universe) has been and will contuinue to be designated and UNdesignated even more in the future.. And that Time in all its perceptions by humans is/may be a MENTAL construct.. a physical brain thing..
