Dark matter is believe to make up for most of the matter in the creation and yet we know very little about it . What we have discovered is mostly through collateral methods , and now thanks to one of those , a new hypothesis for dark topic has been put in interrogation .
A few months ago , a group of research worker hint thatdark matter might be “ fuzzy ” . They claimed that it was made by such small mote , 10 trillion times smaller than the mass of an electron , that the quantum mechanically skillful prop would toy a all important role . These hazy sorry topic particles could interact with each other over 1000 of light years .
But raw simulations based on intergalactic gas do n’t support the idea that blurred dark topic can calculate for all the dark matter . accord to the field published inPhysical Review Letters , the presently accepted model , known as cold dark thing , is still the in effect at excuse what we see in the universe .
" For decades , theoretical physicist have tried to realise the properties of the molecule and force that must make up sorry matter , " lead author Vid Iršič , from the University of Washington , enunciate in astatement . " What we have done is situation constraint on what black subject could be – and ' foggy dark thing , ' if it were to make up all of dark matter , is not consistent with our data . "
Cold dark matter is expected to be made up of weakly interact massive particles ( WIMPs ) , lento moving across quad . They do n’t interact with light and only interact with gravity . The guess holding of cold dark matter have been used in several modelling to successfully promise properties of the universe , but it has also some drawback . For instance , models suggest that the whitish Way should be surrounded by century of low orbiter wandflower , while in realness there are only a few dozen . Also , we are yet to discover a single chicken , although many experiments are presently expect for them .
blurred dark matter solves some of the cold dark matter issuing , so Iršič and his co-worker used a supercomputer to see how the distribution of intergalactic gas would be affected in the blurry scenario . If most drab topic is as light as the muzzy supposition await it to be , then the hooey between beetleweed should be distributed in a unlike way .
" The mass of this particle has to be larger than what mass had originally expect , ground on the fuzzy dark affair solution for progeny surrounding our galax and others , " add up Iršič .
morose matter uphold to stay a enigma , and hopefully we ’ll get some answers soon .
