Is Time An Illusion?

You aren't aging. It just seems like you are. Time is an illusion.

"
JUST because we perceive time flowing in one direction, does that mean there "really is" a difference between the past and future? The old philosophical question has been re-examined by Huw Price, of the University of Sydney, in the context of quantum mechanics. He concludes that the idea that the past is not influenced by the future is an anthropocentric illusion, a "projection of our own temporal asymmetry". By allowing signals from the future to play a part in determining the outcome of quantum experiments, he can resolve all the puzzles and paradoxes of the quantum world."

"
Many physicists find such ideas abhorrent, because they run counter to "common sense". They would, for example, encourage speculations like those of Henry Stapp (see Science, XX August), that our own minds can influence things that have already happened. The power of Price's approach, though, is that it offers a framework for understanding how the world can include both forward and backward causation at a fundamental level, but appear to have a unique direction of time from a human perspective."

Can Time Run Backwards?

If time does run backwards, that means the older you are, the more time you've got left. Live it up all you grampys out there. You'll be young again 80 years ago.

According to a physicist in New York State, the Universe may contain areas where milk would stir itself out of coffee and eggs would un-break. The idea that there may be regions where time runs backwards could explain invisible dark matter. This kind of matter, invoked by cosmologists to explain the movement of galaxies, could originate in a future phase of the Universe - in which the Universe is contracting.
