The true nature of drab matter is still very much ill-defined , so physicists are hear different approach to act out what the mysterious substance is .
A German - Hungarian squad has used the supercomputer JUQUEEN at the German Electron Synchotron ( DESY ) to establish the allow range of hatful that dark issue can have to explain its effects on the universe . The molecule they consider is a good candidate is called the axion , and according to their computation , published inNature , it can be up to 10 billion meter clear than the electron .
There is very warm evidence for the existence of dark thing from cosmological field of study . The shape , size , and statistical distribution of galaxies all tip towards something we can not see . In the last appraisal , from the European orbiter Planck , 85 pct of the matter in the universe is believed to be dark matter .
“ Dark matter is an unseeable form of matter which until now has only unwrap itself through its gravitative effects . What it consists of stay on a complete closed book , ” explains co - author Dr Andreas Ringwald , from DESY , in astatement . “ The adjective ‘ dark ’ does not just mean that it does not utter visible light . It does not appear to give off any other wavelength either – its fundamental interaction with photon must be very weak indeed . ”
While infer it on cosmic ordered series has been heavy , the search for actual molecule of dark matter has been even more difficult . Dark matter is not predicted by the most accurate theory of corpuscle physics , known as theStandard Model , and researchers like Ringwald are picking at its limitations to get new aperient .
He recently suggestedan extensionof the Standard Model , with the axion as the candidate for dark matter . The axion is require to fix something in our description of the strong atomic force , which keeps protons and neutron nonplus to each other in speck . The firm nuclear force out does n’t seem to have a preference when it number to matter and antimatter , but since the universe of discourse is made of matter , there should be one .
Axions could solve this , but before they can define our physics , we postulate to find them , and so far there ’s no proof of their existence . Yet , there are some current and planned experiment that are designed to depend for them that might find some evidence .
“ However , to find this kind of grounds it would be extremely helpful to know what kind of mass we are looking for , ” carry on Ringwald . “ Otherwise the search could take decades , because one would have to skim far too large a compass . ”
A new supersensitive detector has beenrecently approvedin the US , and it is carry to start trace saturnine matter in 2020 .
