Pre-Big-Bang observational signatures studied in Gurzadyan-Penrose paper and a new scale in Cosmic Microwave Background radiation
The possibility of observational signatures of pre-Big-Bang violent activity is discussed in the newly released paper by V.G.Gurzadyan and R.Penrose
Sir R.Penrose (Oxford), one of the classic names in modern science, author of profound books, has developed a theory, cyclic conformal cosmology, which predicts also effects preceding the present Big Bang. The paper is devoted to those effects and shows that in the data Cosmic Microwave Background radiation obtained by Wilkinson Microwave Anisotropy Probe (NASA) certain characteristics of the found concentric circles are in agreement with the predictions.
Study of such possibly pre-Big-Bang effects in the real observational data is undertaken for the first time.
V.G.Gurzadyan and his collaborators in the paper http://arxiv.org/abs/1011.3711 obtain a new scale for the Cosmic Microwave Background (CMB) radiation: CMB is one of the main sources of information on the early Universe and is characterized by well-established scales, the 2.7 K temperature of the Planckian spectrum and the 10-5 amplitude of the temperature anisotropy; the latter was obtained by COBE satellite (Nobel prize, 2006). These features indicate the hot and equilibrium phases in the early Universe and its large scale isotropy.
Gurzadyan’s team now reveals one more intrinsic scale in CMB properties. Considering CMB as a composition of random and regular signals, they solve the inverse problem and obtain that the fraction of the random (chaotic) signal is about 20 per cent, i.e. the cosmological sky is a weakly random one. This new empirical scale (number) can have important consequences for the theories of the early Universe.
