It was supposed to be a revolutionary breakthrough: last March, a team of scientists found what are known as primordial gravitational waves, or ancient ripples in space-time that would have been produced just moments after the Big Bang, stunning direct evidence of a theory most scientists already hold true.

Or had they? On Jan. 30, two teams of scientists — one operating a European Space Agency telescope and the other the team that submitted the original paper — have decided it was all just a mirage kicked up by ordinary space dust in our galaxy, thus debunking what had been one of the biggest discoveries of 2014, according to a report by the Economist.

Such gravitational waves had long been sought by astronomers, as it would confirm that long-held theory that the universe suddenly expanded rapidly just instants after it exploded into existence, inflating at faster than the speed of light.

Most scientists hold that it is true based on indirect evidence, but so far, no one had been able to provide hard, direct evidence that this is what happened.

It explains why the BICEP2 team had been so excited to stumble upon what it though were primordial gravitational waves, which would have been exactly the direct evidence needed. It would have also allowed cosmologist to settle some key questions about inflation theory, as there are differing opinions on the matter within the scientific community.

However, scientists immediately began to doubt the results soon after the paper was published, as they noted that thin clouds of dust in interstellar space can produce a similar signal. In order to verify that the signal came from primordial gravitational waves, researchers would need to identify and remove such signals from their data, but it appears BICEP2 hadn’t been able to do that, instead relying on the best available maps ofinterstellar dust.

ESA’s orbiting telescope Planck generated better data that was not available to BICEP2 at the time, and its data was featured in the paper to analyze the results of the paper published last year. The result was that when the dust is removed from the data, the signature disappears, dumping cold water on what had been thought to be an exciting discovery.

However, it won’t dull scientists’ zeal to keep seeking evidence of the primordial gravitational waves, as they believe they are out there somewhere. More telescopes will continue to hunt for them, and Planck’s abilities could assist in that effort.
 
The title of the article is irresponsibly misleading in the quest for sensationalism. This is not evidence against the Big Bang itself in any way.

First, the new findings do not discredit the idea of gravitational waves, they just show that the apparent observation was wrong and that the search needs to go on.

Second, gravitational waves are not an essential part of Big Bang theory. In the Wiki article on the Big Bang gravitational waves are only listed under “Other lines of evidence”, thus non-essential.

Gravitational waves were predicted by Einstein, however.

By phrasing it that way you obviously don’t know what the term ‘theory’ in scientific theory entails:

The formal scientific definition of theory is quite different from the everyday meaning of the word. It refers to a comprehensive explanation of some aspect of nature that is supported by a vast body of evidence. Many scientific theories are so well established that no new evidence is likely to alter them substantially. For example, no new evidence will demonstrate that the Earth does not orbit around the sun (heliocentric theory), or that living things are not made of cells (cell theory), that matter is not composed of atoms, or that the surface of the Earth is not divided into solid plates that have moved over geological timescales (the theory of plate tectonics)…One of the most useful properties of scientific theories is that they can be used to make predictions about natural events or phenomena that have not yet been observed.

What you refer to as ‘theory’ is speculation. String theory in fact is speculation, nothing more. The term ‘theory’ in that case is a misnomer, it should rather be called ‘string hypothesis’. Big Bang theory on the other hand is well and firmly established by observational evidence according to the definition above – and so is evolution, by the way.

I do know what it means, and I have a lifelong love of astronomy. I almost got a Master’s in it, actually. I’m not putting down the theory, I’m merely pointing out that people forget it’s a theory. And I haven’t even mentioned evolution, by the way.😉
 
BBC had an article on this last week with a much more meaningful title:
Cosmic inflation: New study says BICEP claim was wrong
Scientists who claimed last year to have found a pattern in the sky left by the super-rapid expansion of space just fractions of a second after the Big Bang were mistaken.
The signal had been confounded by light emission from dust in our own galaxy.
This is the conclusion of a new study involving the US-led BICEP2 team itself.
A paper describing the findings has been submitted to the peer-reviewed journal Physical Review Letters.
 
It’s ok! It was an interesting read and interesting interaction from knowledgeable folks…
Thanks!😃
 
I -really- hate sensationalist titles like this. Most people won’t read the article, which means that they may be operating off a flawed understanding of reality…

There really should be some sort of way to hold people who do stuff like this accountable…

You know, I saw on the Internet the other day that the Big Bang never happened.

Hello Al 🙂 I can’t wholeheartedly agree with your statement.😃 I might go to this:

"Universe or Multiverse"
*Cosmological observations show that the universe is very uniform on the maximally large scale accessible to our telescopes. The best theoretical explanation of this uniformity is provided by the inflationary theory. I will briefly describe the status of this theory in view of recent observational data obtained by the Planck satellite. Rather paradoxically, this theory predicts that on a very large scale, much greater than what we can see now, the world may look totally different. Instead of being a single spherically symmetric balloon, our universe may look like a “multiverse”, a collection of many different exponentially large balloons (“universes”) with different laws of low-energy physics operating in each of them. The new cosmological paradigm, supported by developments in string theory, changes the standard views on the origin and the global structure of the universe and on our own place in the world.

This lecture is free and open to the public.

This doesn’t surprise me at all. It is just a theory. Probably a mixture of accuracy and error, like evolution. Besides, these theories change and get reformulated over and over and over…every generation or so gets a different version.
 
So the evidence they thought they had was in error.
Big deal. It is still a valid theory.
 
You know, I saw on the Internet the other day that the Big Bang never happened.
You’ll find anything you want on the internet, end of the world from planet X, flat earth proven, Pope is Antichrist, …

There is not a single shred of experimental and observational evidence for string theory. I don’t care about ‘mathematical developments’. Mathematics without observational evidence is useless to describe physical reality. Ptolemean epicycles were a beautiful mathematical model for the description of the movements of the sun and the planets around the Earth. Observation proved the model wrong. Wait another 50 years, when string theory will be seen as a giant useless joke that has led physics astray for decades. Fortunately, a number of physicists have already woken up to reality. Read Lee Smolin’s The Trouble with Physics, and you’ll see why string theory is bound to be an epic fail. And by the way, the mathematics of string theory are not even beautiful. My father, also a scientist, refers to it as ‘mathematical spaghetti’.

There is tons of observational evidence for the Big Bang.

“It is just a theory …” I wish people would understand and accept that there is a huge difference between the every-day use of the term “theory” and what it means in science.

On this very thread, post #6, Al Moritz pointed out the difference. Please read.

Really?? How has the “Big Bang Theory” changed over time? Not being a science person I am curious to know.

Exactly, that’s what I was attempting to say myself, thank you.🙂
