Cosmic Background Radiation Data from Planck

Philip E. Gibbs


The Planck data shows that universe is made up of 69.2±1.0% dark energy, 25.8±0.4% dark matter, and 4.82±0.05% visible matter. The percentage of dark energy increases as the universe expands while the ratio of dark to visible matter stays constant, so these figures are valid only for the present. Using the new Planck data the age of the universe is now 13.82 ± 0.05 billion years old. WMAP gave an answer of 13.77 ± 0.06 billion years. The most important plot that the Planck analysis produced is the multipole analysis of the background.
