Many of these are questions I struggled with for a long time. Welcome to the weird world of infinity/eternity.
Before we try to move on, may I suggest looking at https://en.wikipedia.org/wiki/Itzhak_Bars
I’m not qualified to comment on Itzhak Barrs’ theory, but I think there are some possible leads towards a solution in this extract.
I would value comments, generally.

To explain to the layman how this gauge symmetry works, Bars makes an analogy between the phenomena in the 4+2 dimensional world and events happening in a hypothetical 3 dimensional room. In this analogy the two-dimensional surfaces that makeup the boundaries of the three-dimensional room (walls, ceiling, floor) are the counterparts of the 3+1 dimensional world humans live in as observers. In this setting, if you shine light from different directions in the room, you create two-dimensional shadows of the three-dimensional events projected on the surfaces surrounding the room. The shadows and their motions on some wall will look different than those on other walls, ceiling or floor. If observers were never allowed to exist in the room but were confined to live and crawl only on the surfaces of surrounding boundaries, the two-dimensional physicist at different boundaries would then write different physics equations to describe mathematically the shadows he/she sees from those different perspectives. He/she would also believe that the shadows at different boundaries are different physical systems because their equations would not match. Since all shadows come from the unique set of events in the room, it is evident from the perspective of the room that the shadows are not independent of each other. So, there must be a definite predicted relationship between the systems of the two dimensional equations at different walls. If the two dimensional physicists are very smart, with much effort they may begin to discover this hidden information by carefully comparing equations of apparently different systems and from this indirectly understand that what appeared to be many different physical systems are really simply understood as the many shadows of a single set of tree dimensional events that happen in the room. This would look like a fantastic unification of complicated systems in two dimensions as a single simple system in three dimensions. According to Itzhak Bars, this analogy conveys the relationship between 1T-physics in 3+1 dimensions (like the physics on the boundaries of the room) and 2T-physics (like physics in the room). The requirement of only gauge-symmetric combinations of 4+2 dimensions demanded by the gauge symmetry is what forces the observers to experience all phenomena as if they live in 3+1 dimensions. Bars has provided many examples of the hidden information as predictions for 1T-physics coming from 2T-physics at all energy levels, from everyday well understood classical and quantum physics to much less understood boundaries of physics in cosmology and high energy physics. He believes that the 2T-physics approach provides powerful new tools to explore the less known aspects of the universe and build the right unified theory.
