As I understand it, everywhere we look in the universe, the galaxies are moving away from us. If the universe is not expanding, how would you account for what we see?
You're not going to like this answer: "Covering yourself with light as with a garment, stretching out the heavens like a tent." Psalm 104:2
True - compare Isaiah 40:22,26 which not only refers to the expansion/stretching out of the heavens but also links the existence of stars (v.26) to God's power (Hebrew singular koach) and dynamic energy (Hebrew plural ohnim). It is therefore to be expected that plural forms of God's energy are involved with the expansion rate of our universe. Also, since God is invisible it comes as no surprise (to me) that 2 forms of energy involved, gravity and dark energy, are invisible.
Concerning 'tent' it should be noted that the tent of meeting/tabernacle in Scripture is geometrically described as a rectangular prism wherein only 2 dimensions of the relatively flat tent cloths are specified. This may be a hint to how the singularity at the so-called Big Bang was formed since the corner points of the intersection of these tentcloths have no dimensions (reminds me of a singularity).
Also, these tentcloths were relatively flat which is a hint that our universe is 'flat' as many scientists are coming to believe. Quite in contrast with the earth being round (Hebrew chuwg in verse 22 = circle in 2 dimensions, sphere in 3 dimensions).
