The Brobdingnagian legal age of the universe is made of clobber that we can not see , since it ’s invisible to lighting , which has appropriately been named sullen thing , and a strength that repulse gravity , named dark energy . Understanding their genuine nature is very unmanageable and while we can analyse the effect , we are yet to pin down the causes . Now a new theory purpose a union of dark subject and sullen vigour into a single substance : a coloured fluid with electronegative mass .
Published inAstronomy & Astrophysics , this obscure fluid approach proposes a way to combine the two main explanation for dark matter and vigor into a exclusive center .
" We now think that both dark issue and benighted vigour can be unite into a fluid which possesses a case of ' negatively charged somberness , ' repelling all other cloth around them , " generator Dr Jamie Farnes , of the University of Oxford , excuse in astatement .
Negative mass particles have previously been ruled out as an explanation because as the macrocosm expands , it is think they would become less dense . But this young mannikin suggests that these weird molecule are continuously being create in the existence , and thus are not being dilute , bear both alien subatomic particle and change to gravity .
“ To my knowledge , this is the first theory that has incorporated both final result , ” Dr Farnes told IFLScience . “ As a bonus , the possibility then seems to explain not only dark matter , but we also get a possible solution for dark energy – essentially for detached . It seems that a simple minus sign may possibly be capable to solve two of the big problems in physics ” .
The model was test using a simulation of the universe and it was able-bodied to create a practical macrocosm whose beetleweed distribution formed as expect . It ’s an challenging determination , though far from definite proof . But there are path for this thought to be put to the test .
The model expects the statistical distribution of galaxies to be alter in a very specific fashion over the ages of the universe . TheSquare Kilometer Array(SKA ) , a proposed radio scope that if it run ahead will be built in South Africa and Australia , would grow enough datum on the subject that it should be capable to evidence if morose matter , modified gravity , or even this dark fluid is responsible .
The construction of the SKA will begin in 2019 and a more definite answer might come towards 2030 . Since there ’s fourth dimension , Farnes is looking into past information to see if there are suggestions that negative mass particles might exist . He also suggested that CERN could spot them , if they do .
The model , as it currently stands , however , has no account for the nature of electronegative hoi polloi and their origin , which is an important limit . Mass remains poorly understood in particle physics and more work is want . Dr Farnes hopes that his idea is considered seriously even if it is unlawful .
“ Of of course , just because the possibility is improper does not mean that it is correct ! The data point may possibly end up confirming that there are no damaging masses , or perchance that we are completely surrounded by electronegative masses , ” Dr Farnes stated . “ Either agency I am felicitous if we can move a niggling nigher to understanding the lawful nature of our universe . ”
