Funding other universes

Peter Woit has written an interesting post responding to the response by Matthew Kleban (and my reply to his response) to my review of the recent Unger/Smolin book.

It’s not often I get drawn into a discussion about the number of universes in existence (a question about which I have no strong opinion, only having seen a small part of one), but what worries me about multiverse theory is that it appears to be driven more by aesthetics and a desire for a unified theory than anything else.

Woit points out another factor, which is the role of the Templeton Foundation. Funded by the estate of the investment manager John Templeton, it pays out grants worth over $100 million per year, with a significant portion going towards supporters of string theory and multiverse theory.

Seems like investment managers (or their foundations) are buying up scientific theories the same way they buy art, thus distorting the market. A smaller example is Winton Capital’s funding of an investigation into Dark Matter.

Time will tell if they are as successful at picking winners in science as they are in finance. Or maybe it won’t, since the debate about the number of universes has been running since at least the Middle Ages and shows no signs of stopping any time soon.

As Woit observes, multiverse theory and string theory have a symbiotic relationship. Together they perform a similar function as the Efficient Market Hypothesis in economics, which is to provide a perfect excuse for the failure to make any useful predictions.

String theory provides not one set of physical laws which govern the universe, but instead an entire “landscape” of possibilities. The fact that we live in one which actually works is supposed to be because there are multiple universes running different versions, and we got lucky. So while we don’t have proof of multiverse theory (barring any future discovery of a hidden portal to a parallel universe) it can be inferred from string theory. But if the particular version of string theory assumed to govern our universe is just a random choice, then that makes it inherently untestable as well.

Perfect example of the Science Games, now sponsored by fund managers.
