[quote]There was little need, before, to know exactly how much dust peppers outer space, far from the plane of the Milky Way. Scientists understood that the dimly radiating grains aligned with our galaxy’s magnetic field and that the field’s twists and turns gave a subtle swirl to the dust glow. But those swirls were too faint to see. Only since March, when researchers claimed to have glimpsed the edge of space and time with a fantastically sensitive telescope, has the dust demanded a reckoning. For, like a cuckoo egg masquerading in a warbler’s nest, its pattern mimics a predicted signal from the Big Bang.
Now, 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.[/quote]

Posted about this before but with new analysis it's seeming more definitive.
Perhaps the universe is just one long ass train of gas and particles combining together to form galaxies and planets and stars, with the big bang being a big explosion which knocked galaxies away from the explosion, hence the red shift of galaxies.

Lol creationists are going nuts in the comment section of the dailymail article for this.

"God is science, no ones told the scientists yet!"
truly top quality argumentation
So does this mean it no longer evidences the big bang? Forgive me if I am comparatively astrophysically illiterate.
What a bummer.

i think it means the opposite

The big bang wasn't really in question, but it's no longer strong evidence of inflation.

No, essentially this group had been looking for a specific wave and hoped to find it in a area that they assumed had no dust in it, however there was actually more dust than they thought and it's contaminated the results making them unreliable. The wave may actually be out there but due to dust contamination there's no way of knowing if the results are reliable or not.
Essentially the quest for more evidence of inflation (not so much the big bang) goes on
We can't see the cosmic trees for the stellar forest.

Inflation I take it means the universe expanding?
[quote]Whereas the initial BICEP2 analysis pegged r at 0.2, corresponding to certain large-field inflationary models, the Planck study lowers its value much closer to 0. If the waves are detectable at all, a much more powerful telescope than BICEP2 will be needed to perceive them behind the swirly haze of galactic dust. Already, at least 10 existing or planned experiments have sufficient sensitivity to detect B-modes weaker than r = 0.1. The Atacama Cosmology Telescope, South Pole Telescope, and the combined BICEP/Keck Array all should be capable of measuring B-modes from gravitational waves within two to three years if the signal is larger than r = 0.01. A balloon-borne instrument called SPIDER will eventually achieve similar sensitivity.[/quote]
While disappointing, it's not really unexpected since multiple experiments have been going on since BICEP2's data collection ended. BICEP2 ended observations in 2012, it just takes a long time to analyze data. I imagine if anything else emerges out of the currently running observatories they will try to minimize the fanfare.

It was a hypothetical period of very rapid inflation in the early universe. Big bang models already have the universe expanding, but inflation is a short period of expansion much much faster than normal big bang stuff predicts, and it explains a lot of stuff like why the universe looks very flat and the cosmic microwave background is very uniform.

Snip, JohnnyMo is much better equipped to explain this.
But anyway, this possible discovery wouldn't conflict with the idea of expansion itself--just whether or not the 'signal' we've been receiving from the Big Bang is direct indication of it.

Nope. See above. Expanding space has been known since Hubble in the 20's.

You're quick.
Do you know how we discovered cosmic background radiation?
A couple scientists at AT&T's Bell Labs were experimenting with a really big receiver for microwave data communication signals from a satellite, and heard some weird shit when they pointed the antenna at the sky
at first they thought it was like some birdshit in the antenna (thing was gigantic) but after thoroughly cleaning the thing, it was eventually concluded that they were receiving a kind of "background" radiation than the microwave signals they were looking for.
AT&T discovered some of the most important technologies of the 20th century, and anybody interested in the history of technology and american history should read [url=http://www.amazon.com/The-Idea-Factory-American-Innovation/dp/1594203288]"The Idea Factory: Bell Labs and the Great Age of American Innovation" by Jon Gertner[/url]
