I like to think of the universe as a giant wave-mechanical interference pattern. Particles are the result of the interference of waves from at least two sources. Those sources are masses existing in mathematical space. Mathematical space is not a space per se, but a non-physical regime of logic only. At least two hyperuniverse masses exist superposed, and their interference gives rise to all the particles that are contained within our cosmic event horizon. Relative velocities demand the exchange of information, and therefore mutual gravitational binding. That information is manifest logically at all times, but not necessarily physically at all times.

I have a notion, perhaps incorrect, that quantum phenomena are absolutely predictable, if one knows the state of the interfering hypermasses. At this point you might say this is untestable...

Test this:

As two objects in an accelerating reference frame experience length contraction and time dilation, does the space between them dilate? Is this space dilation time-like? Can the Hubble constant be expressed as a collapsing constant instead? Is this not time-like space dilation such as that predicted for the interior of a black hole?

If this is true, then there is strong agreement that the universe is gravitationally bound within an event horizon, and the requirement that all detectable particles must exchange information exists. This leads to the prediction of multiple superposed hypermasses in a mathematical space.
