How the Planck Discovery Could Point Toward a New Physics

Posted March 23, 2013 1:42 PM

From Christian Science Monitor:

Europe's Planck spacecraft has revealed the most detailed map yet of the earliest light in the universe, which reveals some tantalizing anomalies that could point toward new physics.

The new map tracks small temperature variations in the glow pervading space called the cosmic microwave background (CMB). This light was released just 380,000 years after the Big Bang, and contains a record of how our universe came to be.

By and large, the new data from Planck agree with cosmologists' leading ideas about how the universe formed. The theory of inflation suggests that after the Big Bang, the universe ballooned rapidly from its tiny, hot state, doubling in size every 10^-35 seconds (a decimal point followed by 34 zeroes and a one).

"One of the features of inflation is it says there should be no preferred direction - everywhere in the universe should be more or less the same...But when you look at the amplitudes, even by eye you can tell that one side of the universe looks different from the other side."

"That is to say, the temperature variations in the CMB appear to be sized and spaced differently when Planck looks in one direction, than when it looks in the other. There are other anomalies as well. The variations don't appear to behave the same on large scales as they do on small scales, and there are some particularly large features, such as a hefty cold spot, that were not predicted by basic inflation models. Ultimately, the data show "some features that are surprising and very, very intriguing"

Very intriguing indeed. Lets hope it leads to some new theory.
