[ad_1] Physicists have long struggled to explain why the universe started out with conditions suitable for life to evolve. Physicists have long struggled to explain why the universe started out with conditions suitable for life to evolve.Why do the physical laws and constants take the very specific values that allow stars, planets and ultimately life to develop? The expansive force of the universe, dark energy, for example, is much weaker than theory suggests it should be – allowing matter to clump together rather than being ripped apart. A common answer is that we live in an infinite multiverse of universes, so we shouldn't be surprised that at least one universe has turned out as ours. But another is that our universe is a computer simulation, with someone (perhaps an advanced alien...

[ad_1] Google shows off quantum computers capable of doing ‘impossible’ computations. Outside, balmy September sunshine warms an idyllic coast, as California basks in yet another perfect day. Inside, it's minus 460 Fahrenheit (-273 Celsius) in some spots, pockets of cold that bristle with the impossible physics of quantum mechanics -- a science in which things can simultaneously exist, not exist and also be something in between.This is Google's Quantum AI laboratory, where dozens of super-smart people labor in an office kitted out with climbing walls and electric bikes to shape the next generation of computers -- a generation that will be unlike anything users currently have in their pockets or offices. "It is a new type of c...
