Disclaimer: I have no formal education in physics. I watched a TedTalk http://www.tedxamsterdam.com/video-wubbo-ockels-on-time-and-gravity/ and it got me thinking. Dangerous, I know. As I understand both velocity and gravity have an effect on our perception of time. How much does our current universe affect our measurement of time, and is there a zero point? The earth is rotating at ~1K mph around its axis We're zipping around the sun at ~67k mph Our position in the galaxy is rotating at ~ 671K mph And then were being pulled by "The great attractor" at 14M mph. If this wasn't enough we have the mass of earth, sun, galaxy, dark matter, etc... further causing distortion. What would be the time dilation between a clock in a static near massless universe (save the clock and observer) and our current reference?
