BICEP2: Digging further

February 6, 2015

You will recall that one of the fatal problems with BICEP2 I identified was that its imaging plane antenna elements were far closer together than the ultimate resolution of electromagnetic wave ( ~ one-third the wavelength – a basic physics limitation.) How did this situation come about?

There is now this paper which explains how the spacing was calculated.Here is the relevant portion:

This paper explains that the antenna spacing was determined inside a wafer of quartz above the antenna slots, with a dielectric constant of 11.8. The thickness of the wafer appears to be about one free space wavelength. The slots are much smaller than one wavelength.

By using the grating lobe criterion they find that the minimum spacing at 180 GHz should be 0.46 mm.

But this calculation is wrong. The dielectric constant that needed to be used in the above calculation is that of air (=1.0). Then the spacing would 1.6 mm – which would have avoided the spacing fatality issue I raised.

UPDATE ON 12/04/2014:

As recently as today, two currently active leaders of the field – both currently receiving government money – are averring that:

… the CMB has a blackbody spectrum that peaks near a frequency ν of 160 GHz …

Is this true?
Where is the Planck CMB Spectrum?
Where is the WMAP CMB Spectrum?

PLANCK COLLABORATION vs BIBHAS DE

THE PLANCK COLLABORATION:
A LONG HISTORY OF SCIENTIFIC COVER UP

1. When it became clear to the Collaboration that the COBE Satellite discovery of the Big Bang Relic Blackbody spectrum was not there in the sky, they made a collective decision to not disclose this.

2. When it became clear to the Collaboration that the WMAP Satellite did not find the said Blackbody, they made a collective decision not to disclose this.

3. Whereas the instrumental botch up with the BICEP2 Telescope is blatantly obvious, the Collaboration decided to issue a strong endorsement by treating the instrument as shishape.

4. The Collaboration is letting the world think that they would perform a beneficial correlation study between the nonexistent Planck sky swirl maps and the bogus BICEP2 sky swirl maps, leading to beneficial conclusions.

5. To this day the Collaboration has not released the actual CMB Spectrum which they possess, choosing to let the world believe in the falsified universe of the said Blackbody. Children of the world are being continually inducted into this falsehood.

This is the true legacy of the Planck Satellite.

In all of the above issues, Bibhas De labored hard to educate the world on the truth.

BICEP2 MEASUREMENTS REAFFIRMED

July 28, 2014

There is an interview with Bicep2 team leader John Kovac of Harvard University published today. In it Kovac reaffirms his discovery, subject to the resolution of the foreground/background issue:

“Our BICEP2 telescope clearly detected a B-mode pattern of polarisation on the sky, matching what would be expected from inflationary gravitational waves.”

The following language confirms that the Planck scientists accept that the Bicep2 sky measurements are valid (on equal footing with the Planck measurements), but that the discovery is subject to resolution of the foreground/background issue (the dust issue):

“Fortunately we have now agreed to directly collaborate with the Planck team on a joint analysis which will combine our ultra-deep BICEP2 maps with their Planck maps at a wide range of frequencies to assess galactic emission, and we hope this will produce results that will reduce the uncertainties very soon.”

[The reader should remain mindful that the above analysis will require the observed CMB spectrum. The currently accepted blackbody spectrum is fraudulent, and the actual spectrum – though known – has never been released. So clearly some BICEP2-Planck collaborative hanky-panky is going on here, and will be going on when they deal with the new data. The taxpaying public is being royally screwed because nobody is ever telling them the truth. Neither BICEP2 nor Planck is deserving of public trust in this proposed collaboration. The fact of the matter is that this “collaboration” is meaningless and deceptive: It is like pooling together of investors’ funds between Warren Buffett and Bernie Madoff in an attempt to rescue the latter.]

Kovac’s concluding sentence makes the BICEP2 discovery entirely contingent on the Planck sky measurements, thus subliminally removing from the public mind any other BICEP2 issues:

“Nothing beats new data to settle a debate, and that’s the great thing about science.”

[Indeed! When Planck had new data disproving the COBE Satellite discovery, they kept mum about it and let the fraudulent discovery stand. Planck thus has a demonstrated “political” propensity for covering the American butt, whatever the science is. It may be these things are being dictated from a much higher level.]

In another accompanying report, Australian scientific experts are also affirming that that the Bicep2 sky measurements are valid, but that the discovery is subject to the resolution of the foreground/background issue.

Australia is one of the leading countries in radio astronomy, and so this position is weighty.

On 24 July 2014, Mario Livio, a scientist at the Space Telescope Science Institute tweeted thus:

“Mario Livio ‏@Mario_Livio Jul 24

@JoelAchenbach My pleasure.I still have some hopes that the #BICEP2 result will turn out to be real (after corrections for dust are made).”

So an internationally concerted position is being promulgated that there are no other issues with the Bicep2 measurements.

My position remains the same.

For me, what is going on is all too familiar: déjà vu all over again. But I must admit that I had hoped that the matter would be handled differently this time around.
