4/24    Seriously.  How practical and close to time travel are we?  I used to
        read quite a bit about this topic when I was young, but have not been
        keeping up with this for the past few years.
        \_ Funny you should mention that, there's a good article about that
           in this months issue of Omni.  Apparently we're pretty close.
           \_ Is the article by any chance online?
        \_ I'm reading this motd entry from the future.
           \_ I knew you were going to say that.
                \_ I knew you were going to say that you knew I was going
                   to say that...
                   \_ Yep, that too.
                      \_ Until I get around to killng both of you *and* your
                         grandparents.  Right after I cleanup in the market.
        \_ When Zefram Cochrane invents Warp drive (a few short years
           now, WWIII has to happen first) we will have everything we
           need to time travel.
        \_ Time is a one-way arrow. Time travel into the future will happen
           in 50-100 years it does not create any paradoxes. On the other hand,
           time travel into the past will never happen, because it creates
           impossible paradoxes, and that points at it violating all sorts
           of things like cause and effect. And it beckwards time-travel
           IS ever invented, you'd have heard about it by now.
           \_ your logic is flawed.  quantum mechanics creates horrible,
              crazy-sounding paradoxes, and yet it has been experimentally
              verified again and again.  The more we explore the crazier
              parts of quantum mechanics like superposition and
              entanglement, the more it all seems to be correct, and it's
              not showing any signs of making "sense".  Time travel may
              well be truly impossible, but to say that it's impossible just
              because of some paradoxes is to ignore the history of physics.
           \_ The Temporal Prime Directive is why you haven't.
              \_ Because in the future people obey all laws to the letter.
        \_ A time-travel date movie: A Happy Accident.
           \_ hah! if you're date won't watch Dr. Who with you she's not
              worth it.
        \_ I read somewhere that time travel is essentially tied to going
           faster than the speed of light.  If it's possible to go faster
           than c then it's equivalent to time travel.  Is that still the
           case?  Isn't c the one true thing that is constant in the universe?
           I need something that is true and absolute in life!
           \_ There is one true and absolute thing about your life.  You
                are a loser.
