What did the bread displace?There is no known viable model of a bang happening at a location in otherwise empty space. So the bread expanding into not-bread space analogy just doesn't work. The bread is the space, and it having an edge would violate the cosmological principle on which all the theories rest.

There is an argument to be made that the expansion of space is directly and proportionately related to the contraction and compression of most of the universe's mass
This concentration apparently includes a significant amount of the "field" or "substrate" that constitutes space-time itself
I keep hearing the Universe is expanding in comparison to like a balloon inflating, the evidence an apparent red shift observed of matter. We do not observe space red shifting we only observe light/matter interaction red shift, so how from that do you conclude the Universe is expanding when that makes no logical sense or is a any sort of rational thought?I read this morning that it is now expanding faster than we first thought and soon and the Universe will become cold and the Universe will end, how on Earth doe's any one derive that ?
To yor-on , I am full agreement with your view ; w/o a global "reality" , no common frame-of-reference is possible . Also , no two things would be able to relate to each other . -----------------------To Europa , Consider that as things gain velocity , they contract . Now suppose that the universe as a whole has gained a very high velocity , in a 4-dimensional sense , being drawn or pushed into the future ever faster . This could cause a type of Lorentz-Contraction , making everything inside of this universe get smaller , relative to the universe itself . If Lorentz-Contraction and Time-Dilation became more pronounced as "velocity" increased ,then time would pass ever slower for the affected contents , leading to the perception that the Universe's expansion was happening ever faster . *.Badda-boom-badda-bang ! In a wild & crazy yuniverse , it could happen ! .🤯
Yes , but... By "fake" they mean that there is no real "matter" , only energy in various forms . In this paradigm , apparently solid objects , from particles to mountains , are composed of "looped" waves of energy . These can become locked together through interactions with various natural forces , thus giving the illusion of solid matter . .*.To examine this more closely , search up "Photon Pair-Production"--------------------------------------Now then , Second-Moon... IF the Universe is , in a sense , plummeting through higher dimensions at ever-increasing speed , does that not engender the possibility that it might eventually hit bottom ? In otherwords , is it not possible that the Universe smashes into a giant pile of dead universes , and explodes like an M-80 dropped into an outhouse pit ? *.Every dynamic system/body in existence produces waste , so doesn't it follow that whoever or whatever made the Universe , did so as a natural function ? .
Now then , Yor-On made an excellent point above ; "we" really do not know exactly what space-time is made of .
No one knows that, in fact the universe might actually be contracting back to where it began. Nothing is known so one theory is as good as the next which is why physicist are now speculating that the universe if fake, nothing more than a simulation
