The 09 fall tv line up includes Robert J. Sawyer's Flash Forward.
Who knew? Probably most people won't ever.
Sawyer's examination of consciousness, relativity and an infinitely self-aware universe poses a simple analogy, "...time is like a bunch of motion-picture frames stacked up, and 'now' is the currently illuminated frame."
A few things to look up in Wikipedia to enhance your viewing and/or reading pleasure:
Many-worlds interpretation MWI or block-universe concept (no point in time is any more important than any other), transactional interpretation TI.
Tipler The Physics of Immortality
The butterfly flaps in China and a hurricane forms off the coast of Africa:
"In chaos theory small changes have big effects over time."
And the proverbial tree falling in the forest:
"Without any conscious beings anywhere, reality breaks down."
"The strong anthropic principle said the universe needed to give rise to life and the Copenhagen interpretation of quantum physics said it requires qualified observers, given what was now known about the interaction of neutrinos and consciousness, the solar-neutrino problem seemed to be evidence that the universe was indeed taking pains to foster the existence of such observers.
