In March last year, scientists believed they had glimpsed - for the first time - the rapid expansion of the universe just after the Big Bang, a theory called cosmic inflation. But since then, the Bicep2 findings have been repeatedly called in to question, with many saying they did not show what they appeared to. And now it seems the final nail has been put in the coffin, as new data is set to reveal that the initial finding was due to the effects of dust in our galaxy - and not cosmic inflation. Gravitational waves from cosmic inflation generate a faint but distinctive twisting pattern in the universe. Shown here is the pattern observed with the Bicep2 telescope, providing what was thought at the time to be evidence for cosmic inflation after the Big Bang. The results have now been called into question . The latest revelations, made using data from Esa’s Planck satellite, are set to be unveiled in a paper early next week. However, according to the BBC, a summary of the paper was briefly posted on the French Planck High Frequency Instrument (HFI) website, before being pulled. ‘Once the "galactic emission" [dust] is correctly subtracted, there still remains an excess [signal] but it is at present too weak to be considered a detection and could be the result of [experimental error],’ the summary has been quoted as saying. A telescope at the south pole, called Bicep2 (Background Imaging of cosmic Extragalactic Polarisation) was used to search for evidence of gravitational waves. The instrument examines what is called the cosmic microwave background, the extremely weak radiation that pervades the universe. The background radiation is not precisely uniform. Like light, the relic radiation is polarised as the result of interacting with electrons and atoms in space. Computer models predicted a curl pattern in the radiation that would match what would be expected with the universe's inflation. It did this by detecting a subtle property of the cosmic microwave background radiation. This is radiation that was created in the Big Bang and originally discovered in 1964. Bicep2 measured the large-scale polarisation of this microwave radiation. Only primordial gravitational waves can imprint such a pattern, and only if they have been amplified by inflation. The latest findings are not entirely a surprise - but will still be a disappointment for anyone holding out hope that Bicep2 was correct. The initial results were made using an extremely sensitive detector on an Antarctic telescope. The team thought they had found a polarisation of light that would have proved the theory of cosmic inflation. To make sure the signal they were detecting was correct, the team subtracted the lensing effect of massive galaxies. But at the time, some scientists said the team had not correctly accounted for interstellar dust in our galaxy. And now, using data from the Planck satellite, which characterised dust in the galaxy, it seems this fear has been confirmed. For their initial research, the Bicep2 astronomers scanned about two per cent of the sky for three years with a telescope at the South Pole, chosen for its very dry air, to aid in the observations. Their research centered on a theory by Albert Einstein when something very explosive happens it leaves ripples in space-time known as 'gravitational waves'. The very first gravitational waves can tell us about the birth of the universe and scientists have discovered they leave imprints in cosmic microwave background radiation - the afterglow of the Big Bang - as they pass through space.

European scientists are to reveal the Bicep2 results were wrong .
In March 2014 scientists said Bicep2 had proved cosmic inflation .
This is the theory that the universe rapidly expanded after the Big Bang .
But analysis by the Planck satellite suggests this finding was just interstellar dust in our galaxy .
The latest findings were to be published next week but leaked today .
