Current speed a t-axis absolute?

Obviously, we are all moving toward the future at a constant speed, which in itself is a form of time travel. What confuses me is how we are able to move toward the future without the advanced techonology we assume is needed to alter our current speed. Also, if our current speed is the natural speed along the time axis, is it a postive absolute? This would mean that one could only travel 'backward' in time at the same or lesser speeds as we normally travel 'forward' at.

Is it obvious? I might offer that it may appear obvious, but that it is EXTREMELY rare in the universe to find anything that is constant. In fact, one major question in physics today would be phrased as "is the cosmological constant really a constant?" Some of the more avant garde theorists (i.e. Jack Sarfatti) believe that controlling the value and polarity of the cosmological constant is the key to not only time travel but also "weightless warp drive".

You have just about answered your question, but I am not sure if you realize it. First of all we need to realize that speed (the scalar measure of velocity) is not ONLY along a time axis... but it is a SpaceTime metric. This speaks to what Einstein told us...namely, there is no "space" and "time" as separate entities. Rather, there is a continuous fabric of SpaceTime. And speed (velocity) is measured as Space per unit Time, so it is a mixed SpaceTime metric. And similar to my statement above about constant speed, it would be quite unusual to find anything in the universe which only has a single polarity, much less that it be "absolute". Certainly all measures of speed (velocity) are always relative measures, and can be + or -.

Mildskp' Time is not a contious flow, in time space, however at times, overlaps, repeats itself and can, at times, be, non steady state.
 
Could it be that the 'future' we head towards is a gravitational body in 4D that is slowly pulling our universe toward it? After writing that I don't know if it makes sense... but it sounded good last night at 12 while watching CSI...

As Rainman pointed out - it really isn't all that obvious that we are moving through spacetime at a constant rate. It took science about 5,000 years to conclude that there is no absolute state of rest and that the rate that time flows is a function of both relative velocity and gravitation.

We each experience the rate of the passage of time independent from every other person (or particle if you want to look at the situation from the micro scale).

And while the rate is almost constant under "normal" circumstances (weak gravitational fields and low velocity) the rate isn't actually constant. If you move parallel to the gravitational field (remain at a constant radial coordinate WRT the center of gravity, i.e. move along the surface of a sphere) the rate varies as a function of velocity (Special Theory of relativity). It you change your altitude WRT the center of gravity the rate changes as a function of both velocity and gravitation (General Theory of Relativity).

You are correct that this is a form of relativistic time travel toward the future.
