scribed in terms of physics taking place on the universe's boundary (surface) ... and each ex-
ists as [the projection of] the holographic image of one possible translation. ..

~~~~ [485] And, as with the case of geometric translations described ealier, this provides yet
another hint that spacetime is not fundamental. Not only can the size and shape of spacetime
change in translation from one formulation of a theory to another, equivalent form, but the
number of space dimensions can change, too. More and more of these clues point toward
the conclusion that the form of spacetime is an adorning detail that varies from one formulat-
ion of a physical theory to the next, rather than being a fundamental element of reality. ...

... To any given observer who is using one theory to think about the universe, [the measured
form of] spacetime may seem real and indespensable. But should that observer change the
formulation he or she uses to an equivalent, translated version, what once seemed real and
indespensable neccesarily changes, too. [Yet, this shift also shows an 'action map' that works
for the observer. Here, too, the 'map' points out the properties of the world that matter now.]
