Everett@50 - Interpretation of Quantum Mechanics: 50 years on
"Some remarkable implications of probabilities without time - Andreas Albrecht
I consider the ambiguity in quantum gravity that arises from the choice of clock. As I emphasize in earlier work (gr-qc/9408023) this ambiguity leads to an absolute lack of predictability for the laws of physics, or more specifically a complete absence of physical laws. I review the clock ambiguity and then consider possible ways forward given this seemingly critical failure. Remarkably, there is an approach that could lead to a certain amount of predictability in physics. I describe this approach and assess its prospects. I also draw attention to possible flaws in the original assumptions on which the clock ambiguity is based, with special emphasis on the definition of probabilities in the absence of time."

News Blog: Hugh Everett: New film tackles "many worlds" theory of quantum mechanics
"If everything physically possible happens in the universe, why do we only see one possibility at a time? That's the question philosophers are beating their heads bloody trying to answer," Byrne tells us. "Everett's answer is there's more than one you, and you are splitting into trillions of copies of yourself every time there's a quantum interaction of a certain size."

"A network perspective is important, because in many complex systems (such as the scientific ecosystem), interaction effects can be more relevant for the resulting system behavior than the properties of the interacting entities themselves. For example, it has been shown that author teams manage to be more successful than single authors11, 12, 13, 14. The social, network-based character of knowledge diffusion underlines this perspective as well15, 16, 17."

Why Does the World Exist? An Existential Detective Story
"Krauss presented these anthropic arguments as “cosmic natural selection,” and a solution to the problem of where the universe comes from. But Jim Holt, author of “Why Does the World Exist? An Existential Detective Story,” pointed out that this line of thinking has a long and not-so illustrious history. What physicists today call the multiverse is known by philosophers as the “principle of plentitude” or “principle of fecundity”: every possible universe exists, and of all these possible worlds, the one we happen to live in is the known world."

"Warwick believes that the technologies required to build an early version of the telepathic noosphere are largely in place. All that’s required, he says, is “money on the table” and the proper ethical approval."
