PCW Davies claims that a human brain neuron requires about 10^120 bits; and therefore, since this is the Lloyd Limit for the available bits in our observable universe, neurons may be at the threshold for consciousness. http://arxiv.org/ftp/astro-ph/papers/0602/0602420.pdf > > > On 6 February 2014 15:58, Richard Ruquist <yann...@gmail.com> wrote: > >> >> An aspect of my string cosmology is that the metaverse contains a >> 4D-space (in which one space axis is time) >> that records every event that ever happened in this and every universe >> much like the Akashic Records. >> Eidetics and gurus can apparently time travel in this block-space. >> Richard >> >> >> On Wed, Feb 5, 2014 at 8:32 PM, Pierz <pier...@gmail.com> wrote: >> >>> The phenomenon of eidetic (photographic) memory is well established as a >>> reality.
