Still More Evidence of Life of Mars

    Interesting... but believeable? Somewhat But, as much as I place faith in ancient writings *snickers*, I must remember the golden rule of humanity: People lie

    I thought the Nephilim lived on our planet X, the planet that may or may not exist in our solar system that is twice the size of jupiter or more.

    It would have been more appropriate for a goatse.cx troll to write "orgasm" as opposed to "organism."

    Just a thought. (And please, Slashdotters, have a sense of humor for a day... You just might enjoy it.)

  9. Your "nasty little truth" sig. by Christopher+Thomas · · Score: 1, Offtopic

    Your sig:

    "Nasty Little Truth About Spacetime Physics" (http://home1.gte.net/res02khr/crackpots/notorious .htm)

    As far as I can tell, this is much hot air to the effect that "time travel is motion through spacetime, which is impossible because it already contains time, so all the physicists talking about time travel are crackpots".

    This seems rather silly, because what physicists actually talk about when they say "time travel" is simply a configuration of an object's world-line (graphed in spacetime) such that the world-line can intersect itself (or that the "future" light-cone from the world-line crosses some "past" part of the world-line, allowing communication, or any of a number of similar scenarios). This does not involve "motion" of the hypothetical fabric of spacetime; it's just a class of paths that objects can take within it.

    Possibly I have misinterpreted the document, but this seems unlikely, as it makes it abundantly clear that time travel involves "motion" of spacetime, which "is impossible".

    Can you clear up this apparent discrepancy?

      Certainly but you misinterpreted my argument. Why is there no motion in spacetime? Because for something to move in spacetime (or in time) it would need to have a variable temporal coordinate. This is impossible because a changing time coordinate is self-referential: it takes time to change, by definition.

      And it is not simply a matter of not being able to move backward in time. There is no motion at all in time, forward or backward. Therefore there is no time dimension. And if there is no time dimension, there is no time travel either, closed time-like loop notwithstanding.

      Um, no.

      Nothing moves in spacetime, and nobody's saying it does.

      Things move in *space*. The motion (velocity) of an object in space at any given time is defined as the derivative of its position (in space, relative to some arbitrary frame of reference) with respect to the time axis on the graph of its position vs. time (its worldline in spacetime).

      Your statement about a "variable temporal coordinate" doesn't make much sense. All I'm doing when I "vary" the time coordinate is look at different points of the world-line, which is most certainly possible.
