<P> Theoretical cosmology studies many alternative speculative models for the origin and fate of the universe beyond the big bang theory . A recent trend has been models of the creation of' baby universes' inside black holes, with our own big bang being a white hole on the inside of a black hole in another parent universe . Multiverse theories claim that every possibility of quantum mechanics is played out in parallel universes . </P> <P> The nature and origin of consciousness and the mind itself are also widely debated in science . The explanatory gap is generally equated with the hard problem of consciousness, and the question of free will is also considered to be of fundamental importance . These subjects are mostly addressed in the fields of cognitive science, neuroscience (e.g. the neuroscience of free will) and philosophy of mind, though some evolutionary biologists and theoretical physicists have also made several allusions to the subject . </P> <P> Reductionistic and eliminative materialistic approaches, for example the Multiple Drafts Model, hold that consciousness can be wholly explained by neuroscience through the workings of the brain and its neurons, thus adhering to biological naturalism . </P> <P> 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 . Quantum mind theories use quantum theory in explaining certain properties of the mind . Explaining the process of free will through quantum phenomena is a popular alternative to determinism . </P>
