TL;DR
Comparative aging between our Earth and Mars and our Moon
Hello,

I thought that it was easy to calculate the difference of aging on different planets, just by knowing the difference of gravity between them.
But it is not so easy...
I will also consider that the difference of gravity will not reduce our age because of other reasons (on muscles, on bones, …).
The calculation that I have done for our Moon and Mars have shown that the differences of the age will be very small, compared to our Earth.
Considering that we will age 100 years on our Earth, I have found that we will age less on our Moon and less on Mars and the differences are the following:

100 years minus 5,847.10-9 seconds on Mars

100 years minus 6,307.10-9 seconds on our Moon

I would like to know if these results are OK for you

Thank you in advance for your comments
Best regards
John

Thank you Ibix for your answer

I have done my own calculation with my own theory
And as this theory has not been seen yet by peers, I have not started by explaining it

If you allow me to discuss about this theory in this forum, I will do

Best regards
John

Personal theories are not allowed on PF (please read the rules). Get it published by an accredited journal and we'd be happy to discuss it.

As @phinds correctly points out, we do not discuss personal theories here. Why not just do the calculation using the standard equations from Relativity that are published in the mainstream literature? What do you get for the differences using those equations?
 
So it is the reason why I don't speak in this forum about my theory.

But could you answer to my initial question about the accuracy of the differences between the ages on our Earth, on our moon and on Mars ?

Thanks in advance

If this is what your personal theory is telling you, your personal theory is wrong. A simple GR calculation shows that, as compared with an observer at rest at infinity, the rate of aging of an observer on Earth's surface is slower than that of an observer on the surface of Mars [Edit: the Moon], which in turn is slower than that of an observer on the surface of the Moon [Edit: Mars]. So the Earth observer will be the one that ages least.

See above.
