Travelling faster than light

  1. Dec 17, 2004 #1
    out of curiosity, who thinks we'll ever be able to travel faster than light (either directly or through higher dimensional shortcuts) ?

    This isn't a physics question. This is philosophy/general discussion. Moved.

    <oh, wait, i cant do that>

    And I don't think we will.

    I agree--sounds like a topic for general discussion.

    Eventually I think that we will be able to do anything provided we live long enough to get there.

    I'd say it would be impossible to stuff my size 8 foot into a size 5 shoe (without modifying one of them). :wink:

    See, that should have been your first clue something was wrong with her. :approve:

    lol, that was the 153rd clue.

    That's a good one. I'll try to remember that.

    Not if your foot were traveing at .... Oh wait, did you need to wear that shoe for a long period of time?

    Anyone who can't nail jello to a tree has obviously never considered temperature. :biggrin:

    As for size 8 feet and size 5 shoes, this is just a gauge problem.

    You can just wait 150 yrs it will will fit in an envelope. :rofl: You are not actually modifying you foot by that is it?

    lol, nobody has a serious opinion?
    And it IS a physics question. We will only be able to travel faster than light if the laws of the universe allow it. I guess it might indeed belong more in general discussion though.

    From a physics point of view, Relativity, which appears to be pretty darn accurate, says that you can not accelerate to a speed faster than that of light. Travelling faster than light will violate causality. However, this says nothing about the existence of things that are always traveling faster than light...except that we can not interact with them.

    I tried giving the Alcubierre Drive paper a look over but it is over my head. But it is said that fits in with relativity and still maintains you can travel faster than light.

    Now, perhaps the research Alcubierre did was right or wrong I don't know, but the way in which he exploits the universe for FTL, it seems plausible perhaps. I don't know, like I said it is over my head so don't take my word.

    Of course we don't have the power required to do it--but that doesn't negate it -might- be possible.
