I am well aware of the mathematical proofs for at least time being a dimension. However, I contend that this will in time be found to be an error.
Well, from a human perspective, time certainly seems to be a different
kind of dimension.
Yet, from a physics perspective, all events have to have at least these 4 coordinates, don’t they?–one of which is time. And when comparing events in accelerating systems (or gravitational fields), what’s ‘simultaneous’ for one observer is not simultaneous for another observer.
And while string theory (or M-theory) is unproven, I don’t see any inherent problem with the idea of there being more than 3 spatial dimensions.
But I’m just a laymen; I’ll let the physicists argue that.
As for the idea that GUT might be a way of looking into the mind of God, I’m sure it would be. But then, all of physical reality is a way of looking into the mind of God.
As a Catholic, however, I believe that there is more to the cosmos than just physical reality. There is also spirit, mind, will. And spiritual reality is another way of looking into the mind of God.
Since I believe that God is spirit, I also believe that there is no amount of physical energy sufficient to ferret out his inner workings, as we might do for, say, subatomic particles.
Finally, I still think it is a mistake for theists to lay all their eggs in the basket of the cosmos having a
temporal beginning. A temporal beginning is no more a
theological necessity than a spatial beginning. I leave it to science to determine whether it is a physical necessity.
I still recall a philosophy professor discussing the argument about the impossibility of an infinite series of causes. His point, reiterated often, was that a
temporal set of infinite causes is not impossible, but an infinite set of efficient causes in the here and now—at this moment—
is an impossibility. And since we are contingent, not necessary, beings, we need an ultimate, non-contingent cause to explain our existence at this very moment. But that’s philosophy, not physics.
