.....no primordial waves has nothing to do with cosmic inflation? 

Inflation is dead, long live inflation! The very results hailed this year as demonstrating a consequence of inflationary models of the universe – andtherefore pointing to the existence of multiverses – now seem to do the exact opposite. If the results can be trusted at all, they now suggest inflation is wrong, raising the possibility of cyclic universes that existed before the big bang.

In March experimentalists announced that primordial gravitational waves had been discovered. The team behind the BICEP2 Telescope in Antarctica had observed telltale twists and turns in the polarisation of the cosmic microwave background radiation (CMB) – the remnants of the earliest light produced in the universe.

Physicists thought the discovery was preliminary confirmation of inflation: the idea that for a sliver of a moment after the big bang there was a blisteringly fast expansion of the universe. The theory, the most widely held of cosmological ideas about the growth of our universe after the big bang, explains a number of mysteries, including why the universe is surprisingly flat and so smoothly distributed, or homogeneous.

But very quickly, the BICEP2 finding was shrouded in doubt, as it was revealed that the polarisation pattern could have been caused by cosmic dust. Cosmologists are waiting for space-based Planck telescope to reveal whether the dust could really make that pattern, and preliminary results released last week suggest dust might be able to.

 

Not to mention symmetry breaking and the universe being full of stuff and no anti stuff which would have occurred had there been cosmic inflation.
