“The quantum theory of parallel
universes is not the problem, it is the solution. It is not some
troublesome, optional interpretation emerging from arcane theoretical
considerations," says David Deutsch.
"It is the explanation, the only one that is tenable, of a remarkable
and counter-intuitive reality. Everything in our universe -- including
you and me, every atom and every galaxy -- has counterparts in these
other universes."
Legendary Oxford physicist David Deutsch is best known for his
contributions to quantum physics, quantum computing, and a leading
proponent of the multiverse (or "many worlds") interpretation of quantum
theory -- the astounding idea that our universe is constantly spawning
countless numbers of worlds.
In his book The Fabric of Reality,
Deutsch laid the groundwork for an all-encompassing Theory of
Everything by tying together four mutually supporting strands of
reality: First: Hugh Everett's many-worlds interpretation of quantum physics, "the first and most important of the four strands"; second: Karl Popper's
epistemology, especially its requiring a realist interpretation of
scientific theories, and its emphasis on being falsifiable; third: Alan Turing's theory of computation, replaced by Deutsch's universal quantum computer; and fourth: Richard Dawkins' neo-Darwinian evolutionary theory and the modern evolutionary synthesis.
"Our best theories are not only truer than common sense, they make
more sense than common sense," Deutsch wrote about the most mind-bending
aspects of particle physics, including the tendency of matter to exist
in more than one place at a time.
In the TED Conference
video below filmed at Oxford University, Deutsch will force you to
reconsider your place in the world, and about our species' significance
in the universe. Far from being simply "chemical scum," quoting Stephen Hawking,
we have the ability to gain knowledge, the importance of which, he
says, is that we are always equipped to solve problems (including global
warming). The brain contains the tools we need: knowledge, reason and
creativity. It's a thrilling, and much needed, profoundly optimistic
argument.
