With regards to what ,does time move forward?

Answer 1

All of the evidence, and all of the theories so far, place time as a dimension qualitatively different from the spatial dimensions. One of Einstein's great contributions was that you can't deal with the spatial dimensions without considering time. All of the string and M-brane theories have only one temporal dimension.

In any inertial reference frame (in spacetime), you are free to choose any reference point. Note that it is a point in spacetime, not in space alone or time alone.

The most physically significant reference point would be the creation of the universe, though we can't locate the time, and especially the place, accurately. The time seems to be around 14 billion years ago.

The most humanly significant reference point is the birth of Christ, though we can't locate that time accurately either. We base our calendar on an estimate of that time.

When you click a stopwatch to start it, you are choosing a reference point.

Unlike the spatial dimensions, motion along the temporal dimension is monotonic, moving steadily only in one direction. With regard to any reference point you choose, time moves forward.

Answer 2

The movement of physical time from that of the present to that of the past moves in relation to its own self. There must be a change in present time value in order for the present to fold into becoming that of the past. The present must make room for other information entering the present. The present disappears totally from instant to instant.

The physics trilogy speaks to this in the following manner: E = mc2, m = E/c2, and c2 = E/m is the trilogy. The last is that of a field of physical time, or that of a field of gravity. The two values we are interested in is that for energy and mass. Notice that in the first the "c^2" value is the multiplier, while in the second it is the divider. In each of these it is the basis of the equation itself. What is interesting about this concept is that all mass and energy within our universe is totally composed of this value. It is for this reason that there exists such concepts as the past, present, and future. Every event moves from "present time" to that of the "past", which means our universe moves in a single direction.

Mass (which must exist in order for the concept of time to exist) moving to the speed of light would change into electromagnetic energy. Mass would change from being a three dimensional entity into becoming that of physical time. This may be thought of as m = c^3, or a cube of time. A cube of time "c3", as I remember, is that of 1 kg. or 2.2 lbs.

So, what does time more relative to - only itself; past, present, and future.

Answer 3

time is the interval between events. it is measured in the intervals of start to stop.

Answer 4

Three dimensional space.
