During the accelerated enlargement of the other universe , the production of theHiggs boson — the elementary particle responsible for giving mass to all particles — should have led to imbalance , follow by prostration . At least that ’s what some late studies suggest .
But the universe of discourse did n’t crack up instantly after the Big Bang , and now research worker think they know why . The response is n’t some novel physics that we have yet to translate : It ’s quite only , somberness . Thespacetime curvature(gravity , in effect ) provided the stability need for the universe to survive early expansion , according to a newstudypublished inPhysical Review Lettersthis week .
An international team lead byMatti Henrikki Herranen from the University of Copenhagenstudied the interaction between the Higgs molecule and gravity , and how it varies with energy . Even a small fundamental interaction , they rule , would be enough to stabilize the universe against decay .
“ TheStandard Modelof subatomic particle physics , which scientists use to excuse unproblematic particles and their interactions , has so far not provided an solution to why the universe did not collapse follow the Big Bang , ” study co - authorArttu Rajantie of Imperial College Londonsays in anews release . “ Our research investigate the last obscure parameter in the Standard Model — the interaction between the Higgs mote and gravity . ”
He adds : “ This argument can not be measured in corpuscle accelerator experiments , but it has a big result on the Higgs unbalance during pretentiousness . Even a relatively small value is enough to explain the survival of the population without any new aperient ! ” Here ’s a timeline of the population :
Next , the team require to look at this fundamental interaction in more detail using cosmogenic observations from current and futureEuropean Space Agencymeasurements of cosmic microwave background radiation ( above ) and gravitative Wave . The cosmic microwave screen background is a snapshot of the honest-to-god Christ Within in the universe , back when it was just 380,000 age old . The observations could help explain the effect that their interaction would have had on the development of the early universe . “ If we are able to do that,”Rajantie says , “ we will have supplied the last unidentified number in the Standard Model of particle physical science . ”
