"Big Bang Signal" Could All Be Dust

An anonymous reader writes Scientists have shown that the swirl pattern touted as evidence of primordial gravitational waves — ripples in space and time dating to the universe's explosive birth — could instead all come from magnetically aligned dust. A new analysis of data from the Planck space telescope has concluded that the tiny silicate and carbonate particles spewed into interstellar space by dying stars could account for as much as 100 percent of the signal detected by the BICEP2 telescope and announced to great fanfare this spring. The Planck analysis is "relatively definitive in that we can't exclude that the entirety of our signal is from dust," said Brian Keating, an astrophysicist at the University of California, San Diego, and a member of the BICEP2 collaboration.

EVEN IF!

Even if it is all dust, the discovery is "nothing to sneeze at"!

Where's the red button?

Educated stupid scientists never understand 4 sided universal timecube.

I was just asking Tess about her act, and all she would tell me was that the show was big -- bigger on the inside than the outside. So I guess there was a lot of seating. A bunch of folderol, if you ask me. But at least we had box seats.
