Scott Adams tells us about the illusion of time:
People keep sending me links to articles about how time is an illusion and not a quality of the universe. Apparently that is the common view of physicists. Scientists prefer concepts such as warped space-time and whatnot. I won’t pretend to understand any of that. The point is that science doesn’t recognize time — in the way we understand it — as a quality of the universe.
You might say time has something in common with God. Most people have a sense that both time and God exist, and they need both concepts to understand their own existence. Atheists and dyslexics (who experience time out of order) are the minority.
Given that science can’t find evidence for either God or time, it takes a leap of faith to assume either one exists. Therefore, anything in our daily life that depends on either God or time is built on a foundation of faith and not science.
I’ve often thought that time is a property of memory. If you damaged the part of your brain that manages memory, to the hippocampus or surrounding cortices – say a combination of retrograde amnesia and anterograde amnesia – what would your experience of time likely be? If you couldn’t remember what happened five minutes ago – and you couldn’t use your memories to predict the future – wouldn’t your experience be just what’s happening right now? Strangely enough, this is what gurus have been telling us for a long, long time: "What’s wrong with right now?"
