If the multiverse contains everything that there is then there is nothing logical about talking about what things would look like for somebody standing outside the multiverse looking back at it. It's a ridiculous waste of time, a complete dead end. >> >> if you start with a unphysical premise then you will reach a unphysical >> conclusion and that does neither mathematicians nor physicists any good. > > > > > That would make disappear a lot of thought experience which have play an > important role in the advance in physics (in Galilee, Einstein, Maxwell, > etc.). > If the works of Galilee, Einstein or Maxwell were built on unphysical foundation s then today nobody would remember their names, instead they are among the most famous physicists of all time. In fact Einstein came up with relativity by trying to imagine what the viewpoint would be of somebody moving at the speed of light and discovered that viewpoint would produce logical contradictions , and therefore CAN NOT EXIST.
