(Phys.org) —In publishing a story regarding work reported by Japanese physicists last month, Nature News has set off a bit of a tabloid firestorm by describing an obscure bit of physics theory as "the clearest evidence ...
(Phys.org) —Present-day physics cannot describe what happened in the Big Bang. Quantum theory and the theory of relativity fail in this almost infinitely dense and hot primal state of the universe. Only an all-encompassing ...
