Yes, I think so. Can you give me a numerical value for the acceleration of the expansion of the universe, and tell me how much this acceleration slows clocks?
Ask your own theorists - according to them expansion of the universe began faster than c. Can you not calculate how much clocks would slow at even near light speed?
Another point. The Earth, Mars and the asteroids are accelerating relative to the Sun, all with different values of the acceleration, and the Moon is accelerating relative to the Earth, again with a different numerical value for the acceleration. In spite of this, the oldest terrestrial and lunar rocks, and meteorites from Mars and from the asteroid belts, all yield essentially the same radiometric ages. What does this imply for your calculations?
They all share the same frame of reference - and their acceleration with respect to one another is nil. But E tried to explain that to you.
"
Special principle of relativity: If a system of coordinates K is chosen so that, in relation to it, physical laws hold good in their simplest form, the
same laws hold good in relation to any other system of coordinates K'
moving in uniform translation relatively to K"
But then you are the very one that is telling me other galaxies are not moving in uniform relation relative to this system of coordinates K, but then claim the same laws are valid, when E told you what requirements must be met for those same laws to be valid. You should of known the answer, did you think that straw-man would somehow disrupt things? Everything sharing this frame of coordinates K is moving in uniform relation to this frame of coordinates K, just as everything on the spacecraft is moving relative to that frame of coordinates k'.
Again, the twin, the spacecraft and everything sharing that frame would be expected to age at the same rate since they are all moving relative to the same frame of coordinates. But at the same time - since you are very aware that the twins clock slows as his acceleration increases - and that to get the rate it ticked earlier in his acceleration you must speed it up, why are you now refusing to accept for our galaxy what you accept for the twin just because our galaxy is the one accelerating and not a spacecraft? You have no valid reason for refusing to do so, except you do not want to have to admit that our decay rates would have been faster in the past, just like the twin on the spacecraft.
Again, the fact that the twin notices no change - doesn't stop that change from occurring. You know it is, that's why you must slow his clocks to get their present rate - but then refuse to speed them up to get their previous rate. But again - you refuse to provide any science to back your claims, while I have given you science after science to show you must.
I even asked you to use the twins clock as it currently ticked to calculate his true age - showing us that you could get the correct answer as you claim you can - you have refused to do so, because you know the answer will not match reality.
You can't claim you understand clocks slow under acceleration, claim everything is accelerating, then refuse to apply the affects to those clocks you know is occurring. Well you can I guess if you refuse to accept the science you understand is valid.
And btw, clocks on earth, mars, GPS, moon, etc all tick at minuscule different rates because of the differences in gravitational energy and acceleration. But that's why there is an error rate of close to 1 billion years.
"Rocks from the Moon have been measured by radiometric dating techniques. They range in age from
about 3.16 billion years old for the basaltic samples derived from the lunar maria, up to
about 4.5 billion years old for rocks derived from the highlands."
Now, stop using clocks you know are slower today than they were 4 billion years ago because of the galaxies acceleration through space and calculate the true age adjusting for the time dilation you know has to have occurred since you know acceleration causes clocks to slow. I am asking nothing from you but what you know is scientifically valid.
