Cosmological Time

Time and distance are used almost interchangeably in cosmology. Measurements pertaining to either can be critical in evaluating truth claims.

The referenced article at Science News is a good case for why we should be skeptical of "computer models" (I know, I used to write models of computer hardware).
"By including in their model previously ignored features such as the maximum possible rate of rotation and subtle shifts in the observed radio frequency due to a pulsar’s motion across the sky, the team finds that some millisecond pulsars are up to 10 times younger or 10 times older than earlier estimates suggest."
