    I much enjoy watching Cosmos by Carl Sagan, Into the Wormhole, and occasionally in my free time doing a bit of independent research concerning various scientific topics. You must understand, however, that my research is very second hand and internet based. I'm just another random college freshman with a few questions on his mind, and with summer about to begin, I have nobody easily within reach to answer my amateur questions.

    So here it goes: I was sitting by myself tonight, slightly bored, slightly stoned, when I started to wonder. If the velocity of an object through space affects the passage of time, which our perception of is limited on a biological level by the speed at which our body systems permit, do creatures on faster moving celestial bodies who have similar biological systems experience time in a different way? As I wrangled with this question, I did some thinking and tried to establish an answer as follows:

    There is as of yet no way to test the biological perception of time while moving at a velocity necessary to facilitate a noticeable difference in its passage, so there is no sure answer. It has been proposed that the perception for an individual on earth versus one travelling at .99c of shaving would be the same due to the limitations of human reference. Yet when the traveler returns to earth he finds that time has contracted for him, and more has passed for the man who remains on earth. In this way, the concept of time as a measurable real thing blurs with the concept of time as warping beyond human perception. If this proves to be true, that time and its passage is not constant regardless of the limitations of human experience, it is an example of the ways in which we as humans overcome our biological restrictions using ideas and mathematical experimentation.

    Although it may seem like I have answered my own question, I wanted to post this to allow others to critique my answer, help me further understand the ideas and questions I'm trying to address, and start a general discussion in relation to the above material between users on this site.

    You focused too much on biological perception.
    If we put two clocks -and left astronauts out of the situation - one on Earth and one on the ship, our measurements would be the same.

    It is interesting, but yes, beings on another body in space can experience time differently. This is due to gravitational relativistic distortion as well.
    So the speed will cause relativistic distortion but the gravity well also will distort the perception of time.
    A being (or human if it were physically possible) on Jupiter would perceive time at a different rate than us on Earth.

    No. All beings experience their time the same way, one second at a time. Nothing seems faster or slower. It's only when observed from a different frame of reference that time appears to run at a different rate.

    If we, on earth, could observe the passage of time on another celestial body moving at relativistic speed with respect to earth, or in a much more intense gravitational field, we would see their time as moving slower, but if we were actually on that celestial body, we wouldn't see any difference in the rate of time. Time always appears to move at the normal rate, from inside the frame of reference.
    Its the way nature is!
