Physicists: Is this idea valid? [View All]

[Ready4Change]

An idea occurred to me a while back, and it still makes sense to me. Don't think I've posted on this here before. Apologies if this is a repeat.

The idea is that everything, all physical objects we can observe, are all traveling at the speed of light.

What do I mean? Here's how I try to explain it.

As I understand it, Special Relativity says that as an objects speed in X,Y,Z space increases, it experiences a decrease in the passage of time. Iow: it's motion through time slows. And as it nears the speed of light in space, it's motion through time nears a complete stop.

This means to me that all objects have a velocity 'budget' of the speed of light. An object at rest in space spends it's entire velocity 'budget' for motion through time. In other words, it is moving through time at the speed of light. In order to move through space at all, it must, through some universal accounting system, withdraw that velocity from it's motion through time.

In other words, for any object, its velocity through space plus its velocity through time = the speed of light.

Does that make sense? Is it old hat for people in physics? If so, is the transfer of 'speed' from velocity in time to velocity in space linear? Iow: if I am moving at .5 C in space, am I moving at only .5 speed in time?

Thanks.
