Then energy is relative? An object is 'stationary' in space, a comet comes along and hits it. The comet has energy. OR the comet is just sitting there, 'stationary', the object hits it. Not the object has energy. There's no total energy to a system, except calculated from some point of view?

energy is a term we use that describes the probability for some unit of matter to be in a different state at time T' than it was at time T. if you consider the state to include position - relative to a frame of view - then energy describes (at least in part) the likelihood that the position at time T' is different than at time T
