Cute!
To measure something, it must be compared to a standard. If you are not willing to consider the flow of time as a standard, then was is your suggested alternative?
The wavelength or frequency of the light emitted my a Hydrogen atom can be measured by time or by length. What standard would you consider the most appropriate?
Please be consistent with your answer and fully understand the implications that it may have.
I am not parsing words here, merely commenting on HIS own words as HE was entertaining the possibility of no baseline standards for the laws of physics.
Sooo, what is your problem with my comment?
But the flow of time isn't really a standard; it varies from place-to-place and object-to-object depending on the local gravity, mass, and velocity.
Mind you, that by itself doesn't exactly get the universe down to 6000 years, but it still begs the question: When scientists say the universe is 13+ billion years old, which part of it are they referring to?
