Lucien,
Sorry, my reply to your last post on 'dimensions' took so long, I've been very busy with other personal matters this past week and unable to get back as soon as I has hoped while making progress when I could.
My thoughts on this topic have nothing to do with string theory. A straight reading of the Bible will do fine. A basic understanding of physics and it's fundamental relation to mathematical formulas proven to hold among space, time, energy, momentum and particle physics should suffice for most people on this topic. Yes there are more than a single time dimension. Peter briefly addresses this in 2 Peter 3:8 whichever way you read the text, God is causal and unbound by our worldly time dimensions and rate of time growth. We are in a universe with an unknown number of other dimensions but likely more than five based on electrodynamics and perhaps ten or eleven as string or brane theory predict. All of these include a unidirectional dimension that involves time. Unidirectional time provides causation in this world and results in ever increasing entropy due to space time expansion. God is in another set of dimensions that includes at least one other dimension of time that He controls to travel anywhen throughout the actualized history of eternity. There is no entropy in His set of dimensions; things there don't wear out. In the new creation or while we are in Heaven, entropy will not increase or wear things out. This implies different physical laws in each set of dimensions, because our set of laws in our dimensions permit wear or growth in entropy.
Time independence must be true, how do you explain foreknowledge, prophesy, and GE 1 (before our time existed, God caused this entire universe including it's time dimension to come into existance at T=0).
Here are some other verses to reconcile with your view of one set of dimensions:
Colossians 1:16 for all things in heaven and on earth were created by him - all things, whether visible or invisible, ....
Revelation 1:8 "I am the Alpha and the Omega," says the Lord God - the one who is, and who was, and who is still to come - the All-Powerful!
Isaiah 34:4 All the stars in the sky will fade away, the sky will roll up like a scroll; all its stars will wither, like a leaf withers and falls from a vine or a fig withers and falls from a tree.
Revelation 21:1 Then I saw a new heaven and a new earth, for the first heaven and earth had ceased to exist, and the sea existed no more.
These passages show that God was present before our universe or anything in it existed and God will continue to exist after our universe rolls up like a scroll and ceases to exist. That God is outside of our universe, but able to make it and also able to interact with it. These verses show that God is capable of creating new sets of dimensions with a completely different set of physical laws than the ones used by Heavenly beings. The verses indicate that at least Heaven and our universe have an independent existence with different physical laws.
The physical laws result from the mathematical relationships among the different dimensions. For different laws of physics, new relationships are necessary. Each change in mathematical relationships will result in new physical laws. Each change in mathematical laws will result in a new environment. For three of the four environments listed in the Bible, different physical environments and laws are described in the Bible that our existing physical laws won't support. If you disagree with this view, what do you think makes these physical laws different in the different places?
How do you rationalize only one set of dimensions for all of these different environments while some exist in parallel; ones that contain spirits, God, material bodies, and totally different physics of operation in each? If you believe in one set of dimensions for all of these places and that the physical laws are not the result of mathematical relationship difference between the dimensions in each that God has established, then what do you believe causes the differences in the physical laws between each place and their isolation from one another?
