Finally, it may provide the knowledge needed to take the field of physics from the grand unified theory (which is essentially everything except gravity) to the holy grail of a theory of everything, which includes this most primordial force.
The two observations: "investigations point towards a compelling idea, that all nature is ultimately controlled by the activities of a single superforce", and "[a living vacuum] holds the key to a full understanding of the forces of nature"; come from Paul Davies' popular 1984 book [4, p.104] entitled "Superforce: The Search for a Grand Unified Theory of Nature".
The author suspects, however, that evolution has been inflated into a grand unified theory of everything.
In his January 2013 cover story about dark matter (page 26), Dan Hooper mentioned the search for a grand unified theory (GUT), which reminded me of a four-line poem I wrote many years ago that had almost slipped from my mind:
Born in 1926 to a working class Punjabi family of Jhang, he later became one of the most important theoretical physicists of his day, contributed to one of the most important theories in Physics, the Grand Unified Theory, and died a proud Pakistani after being celebrated as one of the world's greatest minds.
"When I came out of physics, back in 1985, I really did believe, naively, that financial modeling could be like physics modeling and that there might be a grand unified theory of interest rates," said Derman.
It's all part of an effort that may ultimately forge a kind of grand unified theory scenario of coastal fish behavior--an effort anglers would be wise to pay attention to both for better catch results and for better understanding of management policy.
