    Your own time is always 1 second per second. It's everybody else's time that's dilated.

    Unable to parse that sentence. The words ... don't go together.

    has there been any study whether those who live up high in the mountains age slower than those at sea level?

    if i'm viewing riders on a roller coaster from the ground, time is not different for either person. the only change would be internal such as their experience of weightlessness and g-forces which would have some affect on their internal clock versus mine but absolute time would still be the same. if the ride takes 4 minutes; it's four minutes for them, just like it is for the viewer from the ground.

    the coaster itself and the cart that is moving along the track is not experiencing time dilation. it's fixed and it's not relative. the coaster is not adjusting it's speed in relation to the rider's experience of time. there is no time dilation for the viewer either. the only time dilation was for those on the coaster.

    Life might have started in a n0-sun environment with another energy gradient. now driven by mostly stored solar energy, aka food, fuel. unskilled labor? the fecundity of the uneducated.
    (sorry to hijack a thread on time), would have liked a less destructive outcome. flight of fancy without formulae.

    Correct but change is tiny tiny tiny weeney and not noticeable in normal everyday circumstances

    As I scrolled back I noticed many others had explained the situation

    yes, but the op was trying to say was that the rate of entropy is variable and that is how we measure time. many things affect that rate of change or change, not just gravity, speed or mass.

    This has been irrefutably demonstrated using aircraft and accurate clock
    that is why Einstein liked sailing, he wanted to look younger than his age. (hyperbole) he earlier imagined to ride a wave of light, like a photon, never aging, looking out and seeing us stuck in time. or?
    how about explaining amber's corrected equations?

    P.S.I have a naive question, If speed does slow time (or motion through it,) , but less gravity speeds it up (max gravity stops time) , and gravity falls at /d^2 from the surface, how come the greater altitude does not cancel the effects?

    Me?
    I have no idea.
    They seem real nice.
    Can you show the effects are not cancelled or are cancelled.
    You know the place to look into all this is surrounding GPS.
    Besides telling you where you are it can tell you where you are not...

    Will give more details later

    If you can obtain The Invention of Time and Space by Patrice F. Dassonville

    explains in great detail time and space

    The formula in the original post and reference to Physics seems to indicate only such stuff as gravity etc

    If you're posting about stuff rotting and decaying as the changes with entropy you don't need formula

    Post more later

    thank you for the suggestion. apparently the speeding up of time with heights effect at the satellites altitude is less than the decrease of time with speed. but there is a cancelling altitude for every velocity and
    Satellites operate in zero gravity so, why would there be time dilation because of it? . Is gravity an absolute? even if "centrifugal forces" acceleration of a stable orbit cancels it?

    [QUOTE="amber, post: 3501704, member: 287441" ]---time was absolute.[/QUOTE]
    how about that?

    it would depend on what clock you are using as a benchmark to determine who would be experiencing time dilation given the variables. the caesium clock based on radioactive decay etc.

    I put this little ("check list"?) together. It by no means explains the effects just shows how they act

    Top of tall building

    Top of tall building (less gravity)
    tiny - negative
    = time faster
    NOT fast enough to catch up with the speed effect
    TOP moving into the future

    Top of tall building (move faster)
    tiny ++ positive
    = time slower
    NOT slow enough to fall back or below the gravity effect
    TOP slipping into the past

    On balance - due to speed - moving into future

    Basement of tall building

    Basement of tall building (more gravity) tiny ++ positive
    = time slower
    NOT slow enough to fall back or below the gravity effect
    BASEMENT slipping into the past

    Basement of tall building (move slower) tiny - negative
    = time faster
    NOT fast enough to catch up with the speed effect
    BASEMENT moving into the future

    On balance - due to speed - slipping into the past

    Totality balance of the building - TOP and BASEMENT remain in NOW

    Although it has been says living in the basement DOES let you age mini minor micro slower

    Appreciate if any defects in the above can be pointed out for correction

    I hope the information is correct - I'm thinking more I have not got the information laid out correctly

    I dont think they opperate in zero gravity.
    You may be thinking about weightlessnes a condition that depends in part upon gravity.
    I dont know.
    I am not sure you should look at it that way.

    I'm not sure we know that. There are plausible abiogenesis scenarios that rely on the chemistry of deep ocean hot water vents, not the sun.

    My understanding is that there are good reasons for thinking that photosynthesis arrived quite late in the evolution of life, as shown by the time of arrival of an atmosphere with free O2 in it.

    How can you be so lacking in knowledge of satellites to think they operate in zero gravity???

    You do know the MOON is within the Earth's gravity field???

    And satellites are a lot closer to Earth and much deeper within Earth's gravity field

    Correct βœ“

    NO - well not really

    Weightlessness is a balance between the satellites falling to Earth (yes gravity) and the speed of the satellite pushing it over the horizon

    BUT weightlessness is more NOT HAVING A PLATFORM ON WHICH TO PLACE THE SATELLITE TO BE ABLE TO WEIGH IT

    So the moon is weightless as is the Earth

    Gravity not involved

    How do you know what he is thinking?
    That is what I did not say.
    But did you weigh either of them?

    I do not think you could have such a box, but if you had a box that could stop loss and gain of energy then I assume time would stop for the interior of the box.

    I have a time dilation question for you kind people.

    In the Caesium atom experiment , if a person(s) could count out aloud, fast enough to count the frequency of the caesium atom, when one person is counting slower , does this not just mean they are counting slower?

    They would not make a good musican if they cant keep the beat...if they are not in step they are not really counting anymore.

    Yes they would most certainly be out of synchronisation. But would counting slow affect time?
