The universe appears "old", but it is still less than 10,000 years old

The geometry of space itself is set up anisotropically if you will.

I think I disagree. How do you measure the time it takes light to travel from A to B, and how do you define the time interval delta T which it took? You will implicitly use the "isotropic" synchronization convention to do it. The point is not that this is a deep physical difference, it's just that light travel times for one-way trips are a convention dependent quantity.
