How Universe is expanding faster than speed of light?

  1. Apr 20, 2013 #1
    Hi Guys ,

    Just read this at The NASA site:


    ""Q ......My question is if the universe is accelerating, eventually should it not reach a speed faster than the speed of light? Has anyone investigated the question as to what will happen if the expansion of the universe breaks the light speed barrier?

    The Answer

    A :Thanks for your question. It is true that nothing can go faster than the speed of light. And it is also true that our universe is expanding faster than the speed of light today. This sounds like a contradiction, but....."""

    Could some one explain this to me please ?perhaps a little about length contraction... !sorry I just dont get it!

    Its a metric thing. Coordinates on the graph paper are not constrained.
