Dear Robert,
Indeed what I had to refer as "The collective NOW memory" is wht is available as information on our Subjective Simultaneity Sphere. It also means that it is available for ALL other SSS spheres of any form of consciousness. The center of an SSS is indeed an emerging physical point in our emerging reality with its restrictions of space and time.
If we are expanding the radius of an SSS this new sphere can involve the whole "known" universe with all its known and also unknown (meaning the not yet interpreted and discovered data) information.
This could mean that we are receiving at any NOW moment ALL information (on our SSS) about our specific emerging reality, in the middele ages the "interpretation" of that collective NOW moment was another one as the one we are receiving right NOW, becuse of lack of knowledge.
When looking around in our emerging reality we become aware that only a little part of our consciouss companions are sharing the "knowledge" of the specific NOW we are experiencing.
The accumulated "knowledge" (awareness) of ALL branches of science is available for ALL s data on their SSS. This also counts for the collective "history" of a specific NOW moment that includes the infinity of time before this NOW, only a little part of thsi is available as "knowledge" that we become consciouss of.
You asked me the right question that I am still working on , thank you for that.That is why I like so much the FQXi contest , you are directly confronted with essential questions.
I am going to read comment and rate your essay NOW.
best regards
Wilhelmus
