The basis of our intellect of the cosmos is that the universe is expanding at the same rate in all directions . If so , this would make it " isotropous " as whichever direction we calculate , the universe is the same . If the universe is rather different in various directions , it would be called " anisotropic " – a determination that would ram researcher to rethink a destiny of cosmogeny . This idea is now being put forward in a novel hotly moot study published inAstronomy & Astrophysics .
The squad investigate the cristal - ray discharge of extremely hot gasolene present in 842 clusters of extragalactic nebula . The Assumption of Mary is that clusters with similar temperatures at similar distances should come out equally shining in the sky , but the researchers did not observe this to be the case .
" We saw that bunch with the same properties , with similar temperatures , appeared to be less bright than what we would ask in one management of the sky , and brighter than expected in another direction , " co - author Thomas Reiprich , from the University of Bonn , say in astatement . " The difference was quite important , around 30 percent . These divergence are not random but have a open pattern depending on the direction in which we observed in the sky . "
don that the deviation observed is real , there are two possible scenarios for why : either something is wrong with how we have measured the properties of celestial objects using X - shaft of light or the existence does n’t comport like we believe it to .
" If the Universe is truly anisotropic , even if only in the preceding few billion geezerhood , that would signify a huge paradigm shift because the focal point of every object would have to be taken into account when we analyse their property , " he said . " For example , today , we calculate the distance of very distant object in the Universe by apply a set of cosmological argument and par . We believe that these parameters are the same everywhere . But if our finish are correct than that would not be the case and we would have to revisit all our former conclusions . "
While the finding is intriguing , the sample size of it is minor and more observations are need to explain what ’s bechance . It is important to remark that if the anisotropy is real , it would not just affect X - ray measurements but would be detectable across the plank . The isotropy of the cosmos is one of the all important results in observations of the cosmic microwave background , the first luminosity that shone in the universe , often referred to as the echo from the Big Bang . This luminousness is an embossment of how the universe started as well as how it has changed over the last 13.8 billion days . It is not the last word on the true nature of the Universe , but research worker trust that if the universe had a strong anisotropy as propose in this study , it should have been observe in the latestCMB detections .
investigator go for that forthcoming observance campaigns propose at imaging billions of galaxies to see the nature of the expansion of the Universe will get to the bottom of it .
