Space-Time and Matter

While, like Copernicus' Sun, Einstein's Speed of Light is the fixed element of his system, unlike it, it is not dynamically related to the variable elements therein. In contrast, some recent Physicists have made the stronger analogous claim that the Speed of Light is the origin of Space-Time, and, hence, functions further as a determining factor of those other elements.  Now, aside from the methodological problems with the concept of Space-Time that have been previously discussed--it is a mere heuristic construct that only approximates to its object, Time is actually the Space of a motion in a measuring device, etc.--there is an unresolved substantive problem with the thesis.  For, Einstein clearly distinguishes Matter from Space-Time, unlike Alexander, for example, which demonstrates the shortcoming of this presumed Monism, i. e.  Matter is not derived from it.  But, the well-known illustration of the proposition that Matter distorts Space-Time does more than demonstrate the independence of Matter from Space-Time, it suggests that the former is located in the latter.  Thus, regardless of how exotic the distinction of Relativist Space-Time from the Absolutist Space and Absolutist Time of Newton becomes, the relation to Matter remains the same.
