    would it cause time to slow down for us? Maybe that's why people perceive time as going slower and faster, because maybe it is.

    So when you are on vacation maybe expansion is slower and when you are at work it is faster? Aren't you up past your bedtime?

    Time dilation and the expansion of the universe are two separate things.

    Time does run a bit slower at lower altitudes, compared to higher ones.

    Any effect large enough to be apparent to human perception ought to be measurable and quantifiable. In this case, we ought to see any variations in time on clocks, but we do not.

    What does that suggest to you?

    Dark Energy expands spacetime. Maybe there is a local coefficient that causes some part of it to contract - as in fluid dynamics. Hence, relative speed of time.

    Clocks are too gross an instrument to measure human perception. If I feel like time is moving faster, then maybe it is.

    If you are on vacation and a maid is cleaning your hotel room, you feel like time is moving fast and she feels like it is moving slow but you both are at the same place.

    thus relativistic fields have been proven to exist ?

    Sorry, I can't make any sense of how contraction of spacetime could possibly cause time dilation. You'll need to explain.

    Nonsense. We can measure time down to fractions of nanoseconds. Human perception at best can cope with a few tens of milliseconds, and that's unconscious.

    If everybody around you doesn't agree with you, and clocks don't agree, then its a subjective effect rather than an objective one.

    In a manner of speaking, yes, you could say that, but it's a peripheral point to the one we're discussing.

    Time dilation is a result of a spacetime contraction? Wouldn't you expect time to change as a result of something in contact with spacetime?
    If yes, then I say: So your clock is not engineered to measure it accurately ... back to the drawing board. If yes, it probably scales. Everything changes local time, maybe even paying attention to it. Pure speculation.

    *claps hands while jumping up & down*

    subjective spacial anomalies are dependant on shared perceptual space-time in realatavistic fields ?

    I don't know what that means. It sounds like you're making word salad with random physics terms.

    person A on the ground has a different time line to person B flying in a plane at e.g 100 kilometers altitude.
    time dilation at either point A or point B is dependant on being a shared experience with only those in the same place.
    etc...

    Physics says the time dilation is dependant on the relative motion of the two frames of reference. Shared experience and subjective impression doesn't come into it.

    i am refering to the observational expereince.
    dual experiencer data etc...
    1 being measured in the plane B
    1 being measured on the earth A
    share = more than 1 person reporting data in the same field/ position of relative time
    subjective = data being defined by 2 different fields as independant data that is more than 1 expereincer(=repeatable).

    shared = more than 1 person
    subjective = scientific critique to define what is significant and also accurate data from more than 1 source thus subjective by its nature of scientific fact
    i am probably being a little too Colloquial with my terms

    There would be 2 effects going on in this scenario. Looking at these 2 effects in isolation this is what would be occurring.
    As shown by GR time would pass more slowly for A than B due to their location in the gravitational field. In other words A would say that B's clock is running faster and B would agree with A that his clock was running faster.
    The other effect would be due to relative motion of the 2 frames as shown by SR. As a result of the relative motion A would say that B's clock was running slower but B would disagree and say that A's clock is running slower.

    I passed over reference frames and geometry for the sake of understanding that spacetime - is - time. It contracts when a supernova sends wave shaped forces that cause a pileup of spacetime on the trough's of the waves. Space, and time are constricted, made more dense, otherwise it expands pushed by dark energy which seems plentiful but weak. So I think time is relative, and maybe local. Further, it seems to behave as a fluid, so fluid dynamics, aka local speed of time.

    Moved. First shot across the bow. Like that. So is this pseudo-astronomy? The general spaketh, and they were mediocre.

    localised time.
    time-field
    realative time field...

    realatavised field of localised time...

    field realativity of time

    err-go question(mathamatically)
    is there some way to synchronise 2 different time fields ? (high orbital person flying around the earth at 100,000 kilometers per hour at 300 kilometer altitude
    with someone standing still on the surface of the earth...)

    I have a question. Think of the Earth bending spacetime. I wonder if something in contact with the bottom of the fabric, has the same temporal experience as someone in contact with the top. Is time going faster or slower for either? We are all moving. Suppose I am making toast in the kitchen near the South Pole. How would it be different (timewise) from doing it on the moon? According to the visual I'm thinking about of the Earth causing a divot in spacetime - there should be a difference in time. Am I missing a law of physics somewhere?
