 On the other hand, some scientists, like Andrei Linde, have considered that consciousness, like spacetime, might have its own intrinsic degrees of freedom, and that one's perceptions may be as real as (or even more real than) material objects.Hypotheses of consciousness and spacetime explain consciousness in describing a "space of conscious elements", often encompassing a number of extra dimensions.Electromagnetic theories of consciousness solve the binding problem of consciousness in saying that the electromagnetic field generated by the brain is the actual carrier of conscious experience; there is however disagreement about the implementations of such a theory relating to other workings of the mind.
