I am always pleased when scientific theory sneaks up from behind and confirms what science fiction has been taking for granted for years. I’m even more pleased when the science fiction is my own and the theory is of the kind outlined in this article from a recent New Scientist. (And kindly sent by Valerie.) I have played around with the idea of multiple universes for decades – in psychedelic mode (The DNA Cowboys and Necrom), in theological mode (Jim Morrison’s Adventures In The Afterlife), and in demented short-form (The Adventures Of Marilyn). Now it all proves to be not only highly rational but also on the cutting edge where math meets physics, I find myself unduly and irrationally smug.
“Nothing in the most fundamental laws of physics says that time should only move in one direction. Yet many events are irreversible – shattered eggs do not spontaneously reassemble and ice cubes do not form from pools of tepid water. A new study suggests this arrow of time is the result of quantum mechanical amnesia that erases any trace of such events.
Our sense of time is captured by the second law of thermodynamics, which says that any closed system - from particles in an isolated box to the entire universe - can only become more disordered. The measure of this disorder, known as entropy, can only increase.
In the world of large-scale objects, increasing entropy is associated with the flow of heat, which always goes from a hot object to a colder one. Change in entropy can also be described as a flow of information: the higher the entropy of a system, the less information it contains.” (Click here for more.)
There was also a link in the body of the story to a 2007 piece on parallel universes, but that was an archive article and there’s a fee.
“If you think of yourself as unique, think again. The days when physicists could ignore the concept of parallel universes may have come to an end. If that doesn't send a shudder down your spine, think of it this way: our world is just one of many. You are just one version of many. David Deutsch at the University of Oxford and colleagues have shown that key equations of quantum mechanics arise from the mathematics of parallel universes. "This work will go down as one of the most important developments in the history of science," says Andy Albrecht, a physicist at the University of California at Davis. In one parallel universe, at least, it will - whether it does in our one remains to be seen.”
The secret word is String

"waiting for the lightning to strike - "FLASHBACK: President Bush told French President Jacques Chirac that Iraq must be invaded to thwart Gog and Magog, the Bible’s satanic agents of the Apocalypse. Honest. This isn’t a joke.

Talking of Presidents, Butlin, did you see that Japan's new first lady claims she was once abducted to Venus?
And there is an excellent photo of Gog & Magog on

Was that picture taken by the Hubble?
