Quantum fluctuations

"The Planck data confirm the basic predictions that quantum fluctuations are at the origin of all structures in the Universe," said Jean-Loup Puget, Principal Investigator for the HFI-instrument on the Planck satellite. Viatcheslav Mukhanov, a cosmologist at Ludwig-Maximilians-Universitaet (LMU) in Munich, an expert in the field of Theoretical Cosmology., who first published his model in 1981 and joined the Physics Faculty at LMU in 1997, said: "I couldn't hope for a better verification of my theory."

Data from the Planck telescope have confirmed beyond any reasonable doubt a theory of the quantum origin of structure in the Universe. What exactly happened after the Universe was born? Why did stars, planets and huge galaxies form? These are the questions that concern Mukhanov. He has used the notion of so-called quantum fluctuations to construct a theory that provides a precise picture of the crucial initial phase of the evolution of our Universe: Without the minimal variations in energy density that result from the tiny but unavoidable quantum fluctuations, one cannot account for the formation of stars, planets and galaxies that characterize the Universe we observe today....
