special relativity - How fast can time flow? A question of time dilation


(I would describe myself as an illiterate physics enthusiast, so I hope you'll forgive me if my ignorance is borderline offensive.)


If I've understood anything of the concept of time dilation, your perception of time slows down as you're approaching the speed of light. And I was wondering if you could revert the process and experience time actually going faster if you went out of your way to not move. Suppose you're standing atop of the Sun, observing the Earth revolving, –and for the purpose of this thought experiment, you have no mass because I've come to understand gravity also bends time– am I right to think you'll find earthlings living ever so slightly slower? Then, repeat the process and place yourself atop of the center of the galaxy, looking again at Earth revolving around a revolving star. Even slower?


And then... I realized at this point there lacks an higher traditional referential we could use to "not move" even more as to see Earth's years pass as seconds. Considering time (rather your perception of it) stops when moving at lightspeed, is there an exact opposite phenomenon occurring when at "absolute zero speed" that would make time seem to go infinitely fast? And how would that exist considering any speed is measured relative to something else?
