Have scientists found evidence of a parallel universe?

Caltech cosmologist Ranga-Ram Chary claims that he may have found evidence for the existence of a parallel universe. Many online articles report this.1,2,3 His claim, published in the Astrophysical Journal, suggests some sort of “cosmic bruising” — one universe bumping up against another universe — could explain an anomaly he found in the map of the cosmic microwave background (CMB). The anomaly is in regards to a mysterious blob of light found in the CMB radiation, which allegedly is leftover radiation from the big bang.

USA Today reports:

Chary, a researcher at the European Space Agency’s Planck Space Telescope data center at CalTech, said the glow could be due to matter from a neighboring universe “leaking” into ours, according to New Scientist magazine.

“Our universe may simply be a region within an eternally inflating super-region,” scientist Chary wrote in a recent study in the Astrophysical Journal.

Hey, not so fast with the Nobel Prize!

Already the alleged discovery of not only primordial gravitational waves but also the big bang era of inflation (which I discussed in Has the ‘smoking gun’ of the ‘big bang’ been found? and also in this blog, only a little over a week ago) has been questioned in a paper1 by leading cosmologists. This is in a paper, submitted to the preprint archive (arXiv.org) on March 20th, 2014, just three days after the press release (on March 17th) of the “discovery” by the BICEP2 Collaboration team.

On March 25th a press item appeared on phys.org quoting these cosmologists and entitled ‘Cosmologists cast doubt on inflation evidence’, with a storimagesyline saying

Some theorists are advising that we “put the champagne back in the fridge”… at least for now.2

Has the ‘smoking gun’ of the ‘big bang’ been found?

star burst“Astronomers Just Detected the Beginning of the Big Bang”, “Big Bang’s Smoking Gun Found”, “Astronomers Discover First Direct Proof of the Big Bang Expansion” and “Major Discovery: ‘Smoking Gun’ for Universe’s Incredible Big Bang Expansion Found” were some of the headlines on Monday 17 March 2014 around the web-based news media.

One article described it as follows:

Radio astronomers operating telescopes at the South Pole said Monday that they’ve discovered evidence that the universe ballooned out of the Big Bang due to a massive gravitational force generated by space itself. The discovery is being called the “smoking gun” for the Big Bang theory, and it could have huge implications for our understanding of our universes [sic] (and possible others).

Harvard-Smithsonian astrophysicist John M. Kovac and his team detected gravitational waves—tiny ripples in the fabric of space—that could be the first real evidence for the ‘inflation’ hypothesis of how the universe basically bubbled into being nearly 14 billion years ago. The discovery also suggests that our 14 billion light-years of space aren’t all that’s out there—our universe could be a tiny corner of something much, much bigger.
