The Theory of Relativity is still called the Theory of Relativity.
If you've ever used a GPS, the calculations are constantly adjusted for relativistic effects. Planes are guided to their destinations, and Taliban are blown up, by something that's "Just a Theory."
I am not a believer in the 6,000 year theory. To GOD one of our seconds could(theory) be a million years. Who knows, we will just all have to wait and see.
From what I've read about GPS is the remarkable fact that the calculations do not have to be adjusted by relativistic effects.
