# BICEP2, CMB B-modes And Spinorial Space-time

Mar 26 2014 | comment(s)

Would the existence of B-modes in the cosmic microwave background (CMB) radiation be an evidence for inflation? Many influential colleagues claim that this is indeed the case. But their arguments are based on standard cosmological schemes.

Actually, pre-Big Bang patterns beyond conventional cosmology do not require inflation and can generate CMB B-modes.

Two papers by the BICEP2 Collaboration :

BICEP2 I: Detection Of B-mode Polarization at Degree Angular Scales, arXiv:1403.3985

# A Privileged Space Direction? Spinorial Space-time, WMAP, Planck (II)

Sep 19 2013 | comment(s)

How to present in a simple way the spinorial space-time and the privileged space direction it generates? What is the fundamental difference between space-time spinors and the conventional description of space and time? What is the relevance for the analysis of WMAP and Planck data ?

The spinorial space-time that I suggested in 1996-7 [1,2] naturally predicts a privileged space dimension for each observer. This was emphasized in some of my recent works [3,4], well before the Planck collaboration wrote on March 21-22 [5] :

Two Cosmic Microwave Background anomalous features (...) are confirmed (...). One is an asymmetry in the average temperatures on opposite hemispheres of the sky (...).

Results from Planck and AMS-02, but also the way they are often presented, have created a very exciting situation. Its exceptional character has led me to quickly write an article, Planck data, spinorial space-time and asymptotic Universe, and to make it public for open discussion.

Sorry, I again spent a long time without writing anything here... I hope you are having a happy 2013 in spite of all kinds of "sequestrations" on both sides of the Atlantic.

Here are my two last papers. They will appear in the Proceedings of the ICFP 2012 Conference (Crete, June 2012) to be published by the European Physical Journal Web of Conferences, http://www.epj-conferences.org/ , but can already be found at the following adresses :

Happy 2012 ! I had not been writing any post in this blog since last October.  Furthermore, my first article was not devoted to my own work of this period discussing the OPERA result on a possible superluminal neutrino. See my articles Comments on the recent result of the "Measurement of the neutrino velocity with the OPERA detector in the CNGS beam" (September 28) and Astrophysical consequences of the OPERA superluminal neutrino (September 29).
