The unification of space and time is exemplified by the common practice of selecting a metric (the measure that specifies the interval between two events in spacetime) such that all four dimensions are measured in terms of units of distance: representing an event as (in the Lorentz metric) or (in the original Minkowski metric) where is the speed of light. The metrical descriptions of Minkowski Space and spacelike, lightlike, and timelike intervals given below follow this convention, as do the conventional formulations of the Lorentz transformation.
Hmmmm ....... I see your problem, how can you sleep at night man !!
Anyway, here's one for a lighter moment .....
A rocket explorer named Wright, Once travelled much faster than light. He set out one day, in a relative way, And returned on the previous night !

Condoleeza Rice for intelligent discussion Billy Connolly for the same but with humour Johnny Depp- intelligent and cool! Get out the guitar Penelope Cruz- smart and stunning Bill Clinton- ! Lady GaGa-! Like her style
