I'm wondering if the perception of spacetime as "3 dimensions of space and 1 of time" is a symptom of our inability to maintain an objective view on the matter.
I believe the reason we separate them in our minds is because we seem to have some control over space but no control over time. But this is due to our limitations of velocity, right, not because spacetime is actually "3+1". Relative velocity is what gives control through space and time. Same thing, right? I mean, we don't even really have control over 3-dimensions of space. We only have control across Earth's surface and we only really have that control in 2-dimensions. We need to build machines (airplanes, etc.) to gain control of the 3rd dimension. We'd need another machine to gain control of the 4th. So couldn't we just as easily say that spacetime is "2+2"?
Do you think it would help us to view spacetime not as "3+1" or "2+2" but as it really is; as "4"?
