    Most of the physical activities are independant of awareness . But some activities are dependant upon awareness . How can you explain this with your 'Universe is timeless' philosophy ?

    People assume that time is a strict progression of cause to effect but from a nonlinear non subjective view it's more like a BIG BALL of wibbly wobbly timy wimy stuff! Get it now??? : )

    So , you also agree that , at the atomic or sub-atomic level ; space moves with mass .

    This effect though insignificant at low speed of mass ; but becomes significant , when the mass attains a significant speed ( some ratio of c ) .

    This significant effect can be considered as the cause for 'frame-dragging' .

    So, now we can say that ; at the quantum level , " space moves along with mass " .

    Hansda, I don't believe so. The problem begins to get very complex, since there are some aspects involving GR that may seem similar.

    I have twice started a more in depth reply, only to realize that we are getting a long way off topic and that some of what is involved is perhaps, better suited to a different folder.

    I have no personal aversion to discussions involving fringe interpretations and speculations. I am just not certain this is the best place for those discussions.

    Even GR predicted that , space curves around a mass .


    Unless space moves physically ; how space can curve around a mass ?

    So, space can move physically alongwith mass .


    This movement of space causes frame-dragging , at high velocity of the mass .


    Perhaps , this frame-dragging causes time-dilation or slows down the clock at high velocity .

    Time is change which our clocks measure.

    What is time? In order to understand anything, first identify all the properties of a thing , then organize the prperties in order of significance. When you do this with time it's most significant property will be motion of matter. All definitions of time iply this fundamental property. The second is probably sychronized motion. We use that to measure with. Time for most part represents the quantity of motion of matter.

    Even if you worked on it every second of the day for a hundred years at no moment will you tick onto what Time is. LOL

    While time is represented by a measurement (usually seconds), it is whether or not these seconds represent something beyond just the trivial answer. I mean, understanding time would sort of be like understanding the entire universe, that is, existence and how things came to even be, because theoretically, the mass and energy composing this universe had to have come from somewhere right (or not)? At least based on our predisposition to believe that the universe is a causal system.

    There are times I believe that maybe asking what time is is like asking a question like, "What is norther than the north pole?" That is, something for which the answer simply does not exist based on the false logic with which it is asked, or a question whose answer to which is trivial (Such as does god exist, what is the meaning of life, or who should I vote for next election).

    What we as humans know is based on what our brains communicate to 'us', and what our brain communicates is received based on its sensors which relate information to us about what is going on outside of our bodies. Basically, bats can 'feel' sound, but we can't. What do you think a bat's brain constructs the world like? Who is to say our perception of the world is any more accurate than a bat's? Maybe it's less.

    If you ever play the game telephone, you see that information is always lost or scrambled up by the time the message reaches the end, who is to say the same doesn't happen with our bodies. Maybe our perception of the world is actually skewed because we are failing to detect certain things in our surrounding?

    And who is to say this doesn't expand out from a more fundamental level?

    Based on our current equations of physics, we construct many equations on the speed of light, but I think we know that there realistically is no 'limit' on things in the universe, only limits which we construct which are made to be broken.

    On the other hand, like they say: death and taxes...

    Some things just can't be reversed.

    And time is one of them.

    Hahaha, I don't think I ever said or even implied that we could turn back time, or that I believe in time-travel.

    I believe time is only going in one direction and all you can do at the most is stop it to a crawl or speed it up immensely (relative to your own perception of time), so time travel forward = possible in my views, but backwards = impossible, besides the physical reasons, I think just based on the logical paradoxes you run into, it's already self-explanatory on why it wouldn't be possible.

    No I didn't mean you said that - but you seem open to the idea that maybe reality isn't what it seems to be. I was just commenting on that.

    If there was a reverse time stream, it would be hard to detect, since we're stuck going forward.

    I would like to see a sci-fi depiction (is there one already?) that creates a loop, something like a mobius strip, where one side represents the time in one direction, and the flip side is time flowing in the other direction. The "twist" on the mobius structure would then occur at infinity - negative infinity going the othey way.

    so this loop would have an infinite radius, but what the heck, it's sci-fi, we can live with that.

    It would make for some interesting scenarios. Anyway that's sci-fi, another thread area.

    . . . . but . . . to construct a 'real', physical mobius . . . one must actually . . . make the break . . . and twist the strip 180 deg . . . does time really do that? . . . or is the mobius just a physical construct analog?

    Time is simply an instrument which our brains have made use of to understand why certain things seem to have an order.

    So, if man were to become extinct time would stop?

    In this sci-fi scenario, the two extrema (+∞,-∞) meet. The "flip" represents the transition from a causal to a non-causal world. I was just saying it would make an interesting storyline. So "just beyond" +∞ is the flip and return path out the -∞ end, traversing time in reverse. Looking back, you see +∞ vanishing behind you.
