The European Space Agency has now officially walked back last March's claim that the BICEP2 telescope had found evidence of the universe's early, rapid expansion, but Tabitha M. Powledge warns against making too much of that news: "It is crucial, essential, mandatory to understand that the new analysis does NOT show that the inflation idea is wrong, despite some headlines to that effect. Only that the BICEP2 data didn’t prove it. Inflation theory is still alive and well."
