The universe doesn't age one second with each passing
second of subjective-arbitrary Earth time so what good
is any estimate of the age of the universe? A scientist
living somewhere else in the universe will get an entirely
different result. One of the cornerstones of science is
that if the results are not reproducible everywhere at
every time then they are invalid.
Nonsense.
The universe most certainly does age one second with each passing
second within the frame of reference where the second was defined.
If a scientist living somewhere else in the universe uses the same
frame of reference, he will get the same result.
If he uses a different frame of reference, he will get a different
result which can be converted to our frame of reference and the
result will be the same.
GPS satellites are in a different frame of reference but manage to
provide results that agree with our frame of reference.
What I really don't understand is why understanding frames of reference
is so difficult for many evidently otherwise intelligent people.
