Planck telescope peers into the primordial Universe : Nature News & Comment

Planck’s results strongly support the idea that in the 10-32 seconds or so after the Big Bang, the Universe expanded at a staggering rate — a process dubbed inflation.

Planck telescope peers into the primordial Universe : Nature News & Comment

Big news! Several papers out from the Planck satellite results. The satellite has produced the best, most precise, most detailed look at the Cosmic Microwave Background radiation. The CMB is the glow left behind by the Big Bang when the universe cooled enough to become transparent and photons began traveling freely through space. As space itself has expanded, the wavelength of the CMB photons have increased, leading to the current blackbody temperature of around 2.725K.

Quick takes: at small angles, the CMB is very uniform and consistent with out current understanding (Big Bang, Inflation, a lot of Dark Energy, and Dark Matter). No challenges to Inflation at small to medium angles. The universe is slightly older than we thought, but just slightly. The large angle non-uniformities seen by WMAP, Planck’s older brother, are also seen by Planck. Half the sky is slightly hotter than the other half. The Axis of Evil (an alignment of a significant CMB temperature minimum, a large void of radio galaxies, and an alignment and handedness of galaxy spins) is confirmed. This is a very interesting phenomenon that is not predicted by the Standard Model and the Big Bang.

More later when I have some time to digest the new results.
