    I knew:
    9, 13, 14, 15 & 17, so that`s only 15 things I didn`t know about time, I feel cheated.
    But the ones I didn`t know were pretty interesting anyway.

    Look at all the other "things you didn`t know about" links. The one about sex is really interesting. If you read it and you are against homosexuality, you will no longer have an arguement. I`m not gay, but I believe they should have the same rights as heterosexuals. What`s more is, they did not choose to be gay. (read said article)

    Vanwa, I`d actually thought the same thing about time that the spanish folks did and the description in the article isn`t quite right.

    The big thing about relative theory is that no matter what speed you are going, the speed of light is always a constant. This does some funky things with observable time and space (e.g. Lorentz Contractions, Time Dilation, Observed energy in light, etc) that comes from a result of a different frame of reference.

    Let`s look at the Lorentz Contraction. As you approach the speed of light (relative to someone at your start point) your frame of reference changes, the actual observed distance between things changes and shrinks. Now imagine if you were to return to your original frame of reference.

    Everything would seem to be moving away from you as the Lorentz contraction reversed itself, thus the universe would appear to be "expanding", when in fact, you`re just "slowing down" or "changing reference frame".

    Still

    17 Einstein showed that gravity makes time run more slowly. Thus airplane passengers, flying where Earth’s pull is weaker, age a few extra nano­seconds each flight.

    So, does it mean that if I ever wandered by accident too close to black hole event horizon, time would continually slow down due to gravitational pull, and when near enough center would stop completely?

    Baalthazaq, so while so to me it seems that I`m pulled in there quite fast, and destroyed. But to observer out of the black holes reach, it would seem that me moving one inch would take a million years?

    Pretty much, yes.

    So all in all it`d probably be cooler to push someone in and watch, than to dive in yourself.

    It`s probably wrong of me to suggest that, but I`m fairly certain the situation isn`t going to arise.

    WRONG. It`s due to the acceleration and closeness to speed of light.

    18 According to quantum theory, the shortest moment of time that can exist is known as Planck time, or 0.0000000000000000000000000000000000000000001 second.

    Not exactly true, it`s more of the shortest amount of time which actually means anything. shorter than that and it`s pretty much like measuring a football field in inches, it`s just not practical or usefull.

    20 There may be an end of time. Three Spanish scientists posit that the observed acceleration of the expanding cosmos is an illusion caused by the slowing of time. According to their math, time may eventually stop, at which point everything will come to a standstill.

    -- Which is actually just a hypothesis with no substantial proof. Where as the actual acceleration of expantion is backup up to the ears.

    Regarding #20, when everything comes to a standstill, after time starts back up, could time start moving backwards? They didn`t say if time would go forward or backward.

    i saw something on either discovery channel or science channel about time ending. it`s due to the creation of our moon, when the moon was created it sent the earth spinning, the moon is slowly but surly slipping further and further away from the earth, as the moon moves away our turning (cannot find sufficient word) slows. the reason days were 22-23 hours long way back in dino times is because the moon was closer and "newer" once the moon has slipped away, the earth will have slowed down on it`s axis thus causing "time" to stop.

    at least that`s what i surmised from the program i watched.

    It`s not like you`re just frozen in place, I think it`s like EVERYTHING stops. Including thought, because thought could potentially allow for the recognition of time. Anyway, you wouldn`t know time stopped, and you can`t really comprehend it, but I think you could just basically think of it as the end of the universe. (I don`t really know all that much about the subject, though...)

    LazyMe484: The only reason I am quoting from Wikipedia is because you`ll accept it. If you knew what it is, or bothered researching it, you`d know better.

    "The Planck time is the time a beam of light needs to travel 1 Planck length. According to quantum theory, 1 Planck time should be the smallest unit of time physics can reason about in a meaningful way."

    Planck Lengh undergoes the same definition I gave for time, only with lengh.

    Time certainly is confusing. I mean, when you have adrenaline, your eyes can take in more "shots" per second, which is why time can seem to be in slow-motion when you`re in danger.
    So I wonder... is real time in slow motion, but our eyes just don`t notice it?

    Then what happens to those who observe and are not on adrenaline? Wouldn`t time, for them remain the same? At least in Appearance?

    If they see things as sped up, then the human who is on adenaline is incased in a time bubble, it would be the only way.

    So, does time slow down and not notice, or is he more alert?

    I`d go for the second one :-p

    time isn`t a force. its accepted that its the 4th dimension of our universe, but I question that in my own head. I just have a hard time connecting the concept of time with spacial dimensions. I know they`re related in some sense because one affects the other. But theres something else to it...

    Koala, no. 17 isn`t wrong, as you stated. But what you said about being close to the speed of light isn`t wrong either. According to relativity, both would apply.

    Also I find it quite funny how you tell Silverfalcon that there is no evidence for one of his points, then bring up a point that has no evidence itself.
