“Dark Matter” and to”Dark Energy” are solutions to a false problem.
They were proposed to provide support to the unsupportable assertion that the universe could be unbounded.
The evidence shouts that the universe is bounded, and that its boundary forms a near perfect sphere around our approximate location.

The speed of transport of information in this universe is limited to "C" -- the speed of light.
It is a simple fact that the speed of light (in a universe of sufficient age and size) always limits our observation to a space-time sphere -- centered, of course, on the observer's POV.
Your argument appears to be circular (in 4-D)...
