Time is a Two-Way Street

September 8, 2009

A physicist’s latest theory vindicates Douglas Adams’ description of time as a dimension on which humans only move in one direction.

Compare Maccone’s theory:

Maccone’s solution is to suggest that in fact entropy-decreasing events occur all the time – so there is no asymmetry and no associated mystery about the arrow of time.

He argues that quantum mechanics dictates that if anyone does observe an entropy-decreasing event, their memories of the event “will have been erased by necessity”.

Maccone doesn’t mean that your memories will never form in the first place. “What I’m pointing out is that memories are formed and then are subsequently erased,” he tells me.

…to Douglas Adams:

“….in your universe you move freely in three dimensions that you call space. You move in a straight line in a fourth, which you call time, and stay rooted to one place in a fifth, which is the first fundamental of probability. After that it gets a bit complicated.”

Good thing I take a lot of my philosophical views from British humorists.
