Originally posted by apathistIt's unclear to me whether you are making an ontological claim of your own, or claiming that in the Theory of General Relativity the space like dimensions are physical but time is just a parameter. If the latter then this is incorrect. In Einstein's paradigm the universe is a four dimensional manifold with a Lorentzian metric, which means that coordinate transforms between different observers' reference frames mix the time and space coordinates. They are one substance in the theory. This is a big difference from the Newtonian picture with a three dimensional universe with time as a parameter. However, General Relativity is at odds with Quantum theory. Quantum theories are usually constructed in a specific frame of reference and do not treat time in a completely covariant fashion. So, if you are making an ontological claim then you may be right, but you have to go beyond Einstein's theory to justify it and so it's speculative.

What is space other then the m/e within it?
(Such that it can expand and be curved as if it were a substance.)[/b]
