Here is an outline of my current fantasy......there are multiple 4D (three extended spatial dimensions, one temporal dimension) universes like our own that are linked through a common spatially "collapsed" set of dimensions. I'll accept what ever total number of dimensions a GUT requires, 10, 11, whatever. I imagine that the 6 or so "collapsed" dimensions constitute a common nexus (call it the S-nexus) between all of the various distinct 4D universes.
I imagine that there is a special class of fundamental particles (call these S-particles) that are able to carry information between the various 4D universes, allowing for a type of coordination between them. In particular, each material object in any one specific 4D universe has associated with it a swarm of S-particles which can interact with other similar swarms within the S-nexus. Interestingly, space and time are meaningless within the S-nexus. There, all that matters is the "shape" of the various swarms of S-particles, each of which corresponds to a particular material object at some temporal and spatial location in its particular 4D universe.
What is important is the types of interactions which are possible between the swarms of S-particles within the S-nexus and the effects of those interactions on their associated material objects back in the various 4D universes. What I imagine (and this is all pure bull shit, only designed to make things interesting) is that the physics of the S-nexus are such that similar swarms of S-particles specifically interact in the S-nexus and alter each other. These alterations S-particle swarms can then influence quantum events back in the 4D spacetimes.
I imagine that human brains have evolved to allow a rudimentary exchange of information through the S-nexus which can provide individual human brains some of their "intuitions" about distant events in space and time. We can even propose that sufficiently complex and adaptive S-particle swarms can be coherent within the S-nexus independent of their associated 4D material objects, allowing S-particle swarms to outlive a human and function as an "immortal soul" that could even transmigrate to associate with another human brain.
I imagine that it is possible to develop a science of these S-nexus interactions which would allow for improvement in the efficiency of S-nexus information flow beyond what brains have evolved through natural selection. Such a technology could be used to explore the alternate 4D universes that link through the common S-nexus with our own. We can imagine a type of information trade between alternate universes.
