Momentum in time

  1. Jan 22, 2010 #1
    OK, time (or perhaps sqrt(-1) X time) is our fourth dimension. Do we have momentum as we move through time? When we encounter a gravitational field, does it act to accelerate (decelerate) our "velocity" through time?

    The time-momentum is just the energy! In relativistic physics, energy and the three space components of momentum are viewed as a single entity called 4-momentum. Even in non-relativistic physics, there are indications that energy and momentum have very similar nature (see books on advanced mechanics).
