"Every Galaxy has Counterparts in Other Universes"





“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.




I think there is multivese, and everything point this as much likely true statement, anyway I think that there is not meanful relation between each of these universes. Or just our intellect is not yet sufficient developed to describe real multiverse relations. The base idea of multiverse I think is not yet properly described.

When you ask a religious person where god lives or where heaven is, they might tell you that heaven is neither here nor there. You can't travel to heaven in a space ship or to hell on a big drill deep inside the earth they will tell you. Well then where is it? Same can be said for these other dimensions. Whether the topic is heaven or another dimension, there is too much being assumed with no strong evidence. Our brains are unique among earth creatures in that we can predict and manipulate using physics. This tells me that humans are designed to colonize space. Any species that reaches out from their perfectly safe homeworld to explore and colonize, likely does so for a reason. I remember when I was a child there were so many unknowns and mysteries. Then you grow up and you can see so much more clearly. In the life cycle of a species, we are infants (though you'd think we're in the teenager stage since we think we know everything). It could take a million years for the brain to evolve enough to understand the multiverse. Even then, our species might just be entering the toddler phase.

Personally, I believe in a hybrid between the level one multiverse, with the big crunch theory. In a level one multiverse, the arrangement of molecules repeats itself over unimaginably long distances. In short, there is an identical earth a very very long way from here. The big crunch states that the universe will stop expanding and begin to shrink until everything starts over again with another big bang (a grand scale of Newton's "what goes up, must come down"?). I've heard from a few scientists, that a trillion years is a good number for this life-cycle of a universe. This trillion year lifespan could be called an Epoch and each Epoch is its own universe. Eventually, our solar system would repeat along with us, not to mention countless other Epochs where the earth and humans repeat, but do things slightly different. Granted, a trillion trillion Epochs could happen before we see a close repeat of our current universe.

Assuming this was in fact, reality, it doesn't explain what happens on the outside of the singularity before the big bang and just after the big crunch. Perhaps the reality is a mixture of many types of multiverses.

I don't see where the theories of David Deutsch have any "proof" whatsoever. They seem just to be possibilities rather than having any basis in fact. So why are they so complex? If we are doing away with proof, what's wrong with all the much simpler possible explanations, e.g. Reg Mundy's "The Situation of Gravity", which provides an equally plausible and probable (or improbable!) scenario for our universe without the complexity and also without any "proof". No doubt there are plenty of other similar theories. But in general, the simpler ones are most likely to be true!

I remember saying something like that last week!

Not to agree or disagree but it seems to me its usually a combination of all of the things that are claimed to be the only thing that make the whatever and it always seems to include the simplest to the complex. Try saying that 3 times real fast!
