When looking for that gravity/universe simulator, I ran into Dr. Thomas's description of a universe that "just is," and that time (and expansion) are artifacts of our being embedded in the universe.

I tend to think something in the nature of expansion has to exist, to accommodate the travel of light.

Still the question remains, could the universe exist without invoking the unknown properties of “Dark energy/Matter” ?

If the answer is yes, then why are we wasting/exploring models that can’t be proven ?

If the answer is NO, then how is it that we know anything ?

What other “Dark” properties will we assume and why ?

IMHO, science has transitioned from empiricism to pure speculation. It is the popular acceptance of this speculation that is destroying the foundations of belief.
