Angular momentum and the twin paradox

[DARKSYDE]

If you were spinning on a marry-go-round approaching the speed of light, would you experience time dialation?

If you were spinning on a marry-go-round approaching the speed of light, would you experience time dialation?

Yes, and (in contrast to the linear case), both you AND an observer at the center of the merry-go-round (or any observer fixed to the ground) would agree AT ALL TIMES that YOU are the one who is ageing more slowly.

Could this analogy be applied to Earth and our our solar system and its position on an outter arm of the milkyway? would the way we experience time be different if we were closer to the center of our spiral galaxy?

Could this analogy be applied to Earth and our our solar system and its position on an outter arm of the milkyway? would the way we experience time be different if we were closer to the center of our spiral galaxy?

Yes. If we ignore everything except the black hole at the center for simplicity, being closer to the centre means that you are deeper in the gravitational well, so time passes slower, all other parameters kept constant.
