@yovav,
In my immediate family I have people with PhD's in Psychology, Sociology and Mathematical Physics ... They really have no idea what you are talking about any more than I do (myself being an economist, political scientist and modern European Historian plus multiple business owner).
The question appears to be "Are there further realities to the one we perceive and will it be possible within a later 'model' of human that we will be able to see other possible realities?" .... This appears to be a question of value in someone's mind because we are made up of the same basic building blocks as the rest of the known universe.
Well, the answer we have come up with as a group? No idea. Not enough information known, any answer is pure conjecture and therefore completely without value.
If there are other realities and/or planes of time .... we are still as a species 'banging the rocks together' and who knows if we will survive long enough as a species to actually learn anything of real value about actual time and space.
