First tremors of the Big Bang? Scientists spot evidence of 'gravitational waves' linked to birth of universe | CTV News http://www.ctvnews.ca/sci-tech/real-...purt-1.1732509 Polarization Main article: Polarization in astronomy The cosmic microwave background is polarized at the level of a few microkelvin. There are two types of polarization, called E-modes and B-modes. This is in analogy to electrostatics, in which the electric field (E-field) has a vanishing curl and the magnetic field (B-field) has a vanishing divergence. The E-modes arise naturally from Thomson scattering in a heterogeneous plasma. The B-modes are not sourced by standard scalar type perturbations. Instead they can be sourced by two mechanisms: first one is by gravitational lensing of E-modes, which has been measured by South Pole Telescope in 2013[69]. Second one is from gravitational waves arising from cosmic inflation.. Detecting the B-modes is extremely difficult, particularly as the degree of foreground contamination is unknown, and the weak gravitational lensing signal mixes the relatively strong E-mode signal with the B-mode signal.[70] Reference (19.3.2014): Cosmic microwave background http://en.wikipedia.org/wiki/Cosmic_...ave_background My opinion is that gravitational lensing could be correct explanation for observed B-mode polarization of cosmic background radiation. Those spots in CMBR are size of order super galaxy cluster. I know that Hanna-Maria's diamonds, cluster of Hanna-Maria's diamonds and super cluster of Hanna-Maria's diamonds could cause gravitational lensing which was recently observed in B-mode polarization of cosmic background radiation. Hanna-Maria's diamond is not ordinary matter due it is formed from neutrino matter and it is really 10-dimensional. Form of this diamond is singlecut 8/8 diamond. At present time this kind Hanna-Maria's diamond is in nucleus of almost every galaxy. Hanna-Maria's diamond looks approximately like the following picture of singlecut 8/8 diamond shows (girdle in this picture is removed): http://www.danielprince.co.uk/Diamon..._Diamonds.html I wrote these from year 1992 to about 2013 in the Usenet.

You might want to look again at the data (at http://bicepkeck.org/ ) and in particular at the power spectrum at http://bicepkeck.org/B2_2014_i_figs/powspecres.png . In the lower left plot, the black points show the data, and the red solid line shows the effects of lensing. Lensing is far too small to explain the data at multipole numbers of 50-100 (say sizes of 3-8 degrees on the sky), though it can account for the polarization at higher multipoles (smaller angular sizes). The apparent excess at multipole numbers around 200 is not statistically significant. -- Help keep our newsgroup healthy; please don't feed the trolls.

Steve Willner Phone 617-495-7123 Cambridge, MA 02138 USA Text of Figure2 (http://bicepkeck.org/) you mentioned above: "BICEP2 power spectrum results for signal (black points) and temporal-split jackknife (blue points). The red curves show the lensed-lambda-CDM theory expectations- in the case of BB an r=0.2 spectrum is also shown. The error bars are the standard deviations of the lensed-lambda-CDM+noise simulations. The probability to exceed (PTE) the observed value of a simple Khi^2 statistic is given (as evaluated against the simulations). Note the very different y-axis scales for the jackknife spectra (other than BB). See the text for additional discussion of the BB spectrum." Maybe the model of lensed-lambda-CDM theory is not the correct one? I would try instead here some closed models (=oscillation models) of the Universe. Best Regards, Hannu Poropudas Finland |

Best Regards, Hannu Poropudas Finland In every cycle those Hanna-Maria's diamonds get harder and harder (as I have written in some of my text in above mentioned summary of my articles). In my opinion this solves the entropy problem which is mentioned in the following reference: "Cyclic model Overview In the 1920s, theoretical physicists, most notably Albert Einstein, considered the possibility of a cyclic model for the universe as an (everlasting) alternative to the model of an expanding universe. However, work by Richard C. Tolman in 1934 showed that these early attempts failed because of the cyclic problem: according to the Second Law of Thermodynamics, entropy can only increase.[1] This implies that successive cycles grow longer and larger. Extrapolating back in time, cycles before the present one become shorter and smaller culminating again in a Big Bang and thus not replacing it." (R.C. Tolman (1987) [1934]. Relativity, Thermodynamics, and Cosmology. New York: Dover. ISBN 0-486-65383-8. LCCN 34032023.) Reference 22.3.2014: http://en.wikipedia.org/wiki/Cyclic_model Best Regards, Hannu Poropudas Finland |

I think that our present Universe could be in phase of second cycle not in phase of the first. Reason for gravitational lensing I mentioned my earlier posting. Those Hanna-Maria's diamonds (not ordinary matter) and radiation could be main remains of the first cycle.
