Sheldon: It is becoming clear to everyone that: (a) cosmology behaves as a degenerative research programme; and (b) the problem lies in the BB model first put together in the 50’s and 60’s.

## Rob Sheldon on why string theory’s inflationary cosmos is a degenerate research program

Sheldon: The inflationary proposal has always been ad hoc. That is, a huge, faster-than-light expansion of the universe was proposed as a solution to the “flatness” problem, where the universe expands at a rate just sufficient to counter the gravitational attraction, where “just sufficient” means one part in 10^60 power. The inflationary model was invented to solve this fine-tuning problem.
