  A number of philosophers and scientists have discussed the possibility of
inseparability between the subject (i.e., the observer) and the object (i.e.,
the observed universe). In particular, it has recently been proposed that this
inseparability may be obtained through the discrete physical universe being
filled with the observer's continuous consciousness through quantum evolution
with time going backwards. The proposal of a universe view with interwoven
matter and mind through cyclical time bears a resemblance to Immanuel Kant's
discussion of the Copernican Revolution in philosophy, where the priority
shifted from the object to the subject.
