  •  Einstein never postulated a speed limit (3+ / 0-)

    If you look at his original equation, (E=mc squared divided by the square root of one minus v squared over c squared)
    When v equals c, the equation becomes undefined, with the square root of zero in the denominator.  If v is greater than c, you have the square root of a negative number in the denominator.  The square root of a negative number is imaginary, it I recall high school mathematics.
    So, it doesn't say you can't go faster than the speed of light.  It says you can't measure it or define what happens mathematically when you do.
    I suppose that's why he called the Theory of Relativity instead of the Theory of Absolute Speed.
