Description
The no-boundary wave function can explain the origin of inflation but it favors a low amount of inflation, in conflict with observations. It has been thought that this puzzling property is universal, i.e. independent of the model of inflaton, posing a real conundrum for inflationary theory. We revisit this problem for k-inflation and give evidence that the no-boundary probabilities can be reversed in k-inflation, leading to the prediction of a large amount of inflation.
