A new scientific theory - called biocentrism - refines these ideas. There are an infinite number of universes, and everything that could possibly happen occurs in some universe. Death does not exist in any real sense in these scenarios. All possible universes exist simultaneously, regardless of what happens in any of them. Although individual bodies are destined to self-destruct, the alive feeling - the 'Who am I?'- is just a 20-watt fountain of energy operating in the brain. But this energy doesn't go away at death. One of the surest axioms of science is that energy never dies; it can neither be created nor destroyed.
At first, it's hard to wrap your mind around all of this but the more you read, the more plausible it all becomes. Is it a leap of faith? Perhaps, but no more so than believing in the Christian faith or some other religion. Even Einstein might have been a believer...
According to Biocentrism, space and time are not the hard objects we think. Wave your hand through the air - if you take everything away, what's left? Nothing. The same thing applies for time. You can't see anything through the bone that surrounds your brain. Everything you see and experience right now is a whirl of information occurring in your mind. Space and time are simply the tools for putting everything together.
Death does not exist in a timeless, spaceless world. In the end, even Einstein admitted, "Now Besso" (an old friend) "has departed from this strange world a little ahead of me. That means nothing. People like us...know that the distinction between past, present, and future is only a stubbornly persistent illusion." Immortality doesn't mean a perpetual existence in time without end, but rather resides outside of time altogether.
