I won't pretend to be versed enough in QM to make a cogent point, but here's a snippet of an article that does a fair job:
Hawking is now pushing a different strat egy, which he calls top-down cosmology. It is not the case, he says, that the past uniquely determines the present. Because the universe has many possible histories and just as many possible beginnings, the present state of the universe selects the past. “This means that the histories of the Universe depend on what is being measured,” Hawking wrote in a recent paper, “contrary to the usual idea that the Universe has an objective, observer-independent history.” This idea could cut through some long-standing scientific mysteries. One debate now roiling the physics community concerns string theory, currently the leading candidate for a so-called theory of everything. String theory holds that all the particles and forces in the universe can be explained as arising from the vibrations of vanishingly small strands of energy. But it has one huge problem: Its fundamental equations have a near-infinite number of solutions, each corresponding to a unique universe. Hawking’s idea provides a natural context for string theory. All those universes might simply represent different possible histories of our universe. This notion is as daring and exotic as anything Hawking has ever proposed. Even better, it just might be testable. If Hawking is right, the alternative quantum histories of the universe (the ones we have not observed) may have left a subtle imprint on the cosmic microwave background, the faint radiation left from the hot glow of the Big Bang. Physicists believe that the slight temperature variations in the microwave background were caused by quantum fluctuations in the early universe. Hawking suspects that if other quantum histories really do exist, they may have made their own measurable contribution to the background radiation. Over the next few years, the European Space Agency’s new Planck spacecraft may be able to detect the sort of microwave patterns that Hawking is predicting. -- Jonathan Sherwood Sr. Science & Technology Press Officer University of Rochester 585-273-4726 On Tue, Oct 13, 2009 at 3:30 PM, Eric Scoles <[email protected]> wrote: > > Well, where's the science in it? > > I mean, there's plenty of *scientism*: big words, equations, logical > calculus, even some experimental results.
