    Posted By: DuracellIf 2 objects were moving towards each other at more than 50% of the speed of light then wouldn't the motion of one of those objects appear to be super luminal to an observer on the other object?



    No.

    nearly c. It happens routinely at CERN.

    That's relativity for you.
  1.  
    OK (and yes - I know I will probably regret asking this!), but if 2 objects were travelling towards each other at 95% of the speed of the light, then from the point of view of an observer on one of the objects, what speed would the other object appear to be travelling towards her at?

    Around 0.99 c. It's asymptotic to 1.0 c, meaning it never exceeds c. There's a formula (Lorentz transform) you can use and of course it's in many places online. Try Wikipedia. You can also do a plot from a spreadsheet to see how it goes.

    Good luck with that.

    It's OK because as you go faster and faster, the spreadsheet contracts in length in the direction you are going. SO you never run out of columns to accelerate into.

    (As seen from the outer OS, that is.)
  2.  
    Formulae and graphs are the really useful things about Excel. You can apply the same formulae to a normal data series (1,2,3,4..) and plot the function immediately, and get a feel for the kind of function it is by simply eyeballing it.

    Fortunately for this relativity case, there are numerous examples of graphs showing this asymptotic behaviour all over the Net.

    Nah, it's because my gramdother was from Setallonika.

    This has been going on since Dirac's day and probably before. We don't need no steenkin' multiverse. We just rehash the same theories over and over again in this verse.
