Your age on other planets?

I thought you would be referencing something like this

I’m 30 martian years old

You realize none of the moons of Pluto take more than 40 (Earth) days to orbit?

I tried computing the effect of General Relativity; I hope I have this right. Take three identical clocks, put one in outer space far from any strong gravity fields, another on the surface of the Earth, and another on Jupiter. Then after one year, bring the clocks back together. You will see that compared to the outer space clock, the Earth clock is slow by 0.02 milliseconds and the Jupiter clock is slow by over 640 milliseconds, more than half a second. So if you want to live longer, move to Jupiter.

Don’t be silly.

Superman wasn’t doing anything to the earth; it just looked like it was spinning backwards because he was moving backwards through time. No different than the mountainside uncollapsing and the rockets flying backwards.

Thank you. That always seemed perfectly clear to me.
