Cosmologist: String theory is incompatible with dark energy
Rob Sheldon mentioned a story going the rounds earlier today, about whether dark energy was “even allowed.” Here’s the story, from ScienceDaily: In string theory, a paradigm shift could be imminent. In June, a team of string theorists from Harvard and Caltech published a conjecture which sounded revolutionary: String theory is said to be fundamentally […]
“Expanding blueberry muffin” picture of the universe collapses
And cosmologists race to win a “great cosmic bake-off” to produce a new one, says astrophysicist: Just as cosmological measurements have became so precise that the value of the Hubble constant was expected to be known once and for all, it has been found instead that things don’t make sense. Instead of one we now […]
