I'm not really sure what you're getting at. You're always standing completely still relative to yourself, and that's all that matters If the observer was moving close to the speed of light relative to you, your entire life would pass in a blink (actually this is only true if he made a round trip, otherwise you wouldn't be aging at all from his perspective; it has to do with the fact that the acceleration of turning his ship prevents his from claiming an intertial reference frame). Sim

I don't know who told you that? Perhaps your forgetting to consider how far we are away from the centre of the Earth? Anyone knows that the further away you move from the centre of gravity, the faster you spin and the greater the centrifical force. So if you increased the diameter of the Earth by 3 times, the increased centrifical forces would counteract the increase in mass - to what extent i do not know? We could even end up with less gravity! Firs

Actually, time doesn't slow down at all if I remember my physics class correctly... not on the inside, at least. From the perspective of someone outside, though, time would be steadily slowing down (and whatever you are observing becoming more and more redshifted) the close you came to the event horizon. An excellent point. Even if the sun did somehow have a greater gravitational field than a blackhole, and even if was somehow possible to survive while stand

Nope, the gravity would depend more on the rotation speed than the planet sieze. It is quite possible to live on a planet 5 times the seize of Earth and have half the gravity! The apparent decrease in gravitational force as caused by the earth's rotation is on the order of micrometers per second squared, so no, rotation speed is essentialy irrelevant. We suffer a littlie thing called space-time condencing, if a planet is
