The seeming discovery of the Higgs boson particle last year has opened doors to new calculations that were n’t antecedently potential , scientists say , include one that evoke the macrocosm is in for a catastrophe 1000000000 of years from now .
" It may bethe existence we live inis inherently unsound , and at some point billions of age from now it ’s all croak to get wipe out , " Joseph Lykken , a theoretic physicist at the Fermi National Accelerator Laboratory in Batavia , Ill. , said Monday ( Feb. 18 ) at the annual meeting of the American Association for the Advancement of Science .
Proton-proton collisions at the Large Hadron Collider show events consistent with the Higgs boson particle.
That project is based on a computing of the macrocosm ’s " void instability " that count on the plenty of the Higgs boson , which physicists think they ’ve found at the human race ’s largest subatomic particle throttle , the Large Hadron Collider in Geneva . Scientists therediscovered a raw particlewhose property evoke it ’s the Higgs , though further trial impression is needed to be sure .
But what does this subatomic particle have to do with the luck of the cosmos ?
First of all , the Higgs boson is related to the Higgs field of study , an DOE field pervading blank space that is intend to imbue many particles with mass . Just as swimmer get wet moving through a swimming pool , the thinking goes , particles get mass make a motion through the Higgs theater . [ picture gallery : lookup for the Higgs Boson ]
hill and valleys
The Higgs field of operation has a certain possible Energy Department related to the room it interact with itself . Just as a field of grass has hills and valley — maximums and minimums — the Higgs line of business can have potential energy minimums and utmost , as well , explained Tim Barklow , a physicist at the SLAC National Accelerator Laboratory in California .
presently , figuring suggest , the Higgs field of study is at a potential lower limit , but it ’s possible , at some tip , that the field could " tunnel " to another possible minimum that would give it unlike belongings . ( Tunneling is the quantum mechanical equivalent of boring through a hill from one vale to another , rather than traveling up and then down the J. J. Hill . )
But if the macrocosm ’s Higgs field tunneled to a new potential energy lower limit , it could become much stronger , causing the universe ’s particles to gain passel . Any change in the mass of profound particle like the proton and negatron would have drastic repercussions . corpuscle , planets , stars and galaxies would no longer hold together as they do now if their primal constituents were change .
" Then all the laws of purgative change and everything is torn apart , " order Barklow , who is a member of the ATLAS experiment at the Large Hadron Collider , one of the projects that discovered the potential Higgs boson .
Higgs people
The likeliness of whether or not this eventuality come to go along depends on a turn of property , including the people of theHiggs boson . That was n’t known until just of late , when the Large Hadron Collider produced a never - before - take in particle that looks to be the Higgs . This particle ’s mountain is about 126 billion negatron V , or about 126 times the muckle of the proton .
The void instability of the universe also depends on the mass of the top quark , a relative of the element of the protons and neutrons that make up all the atoms in the universe .
Both the Higgs mass and the top quark mass flex out to be just what ’s needed to make a fundamental unstableness in the Higgs field of operations , and therefore todoom our creation . [ End of the World ? Top 10 Doomsday Fears ]
" The comportment of this phenomenon depends on the top quark cheese being heavy and the Higgs being very wanton , " said SLAC theoretical physicist Michael Peskin . " It turns out the top quark is very big and the Higgs is lighter than a lot of masses thought it would be . "
Doom and sombreness
It seems to be a perfect storm to spell a dismal end to our cosmos in many billions of years . But do n’t worry too much .
" Other things , like the sunshine turning into a violent whale , will happen before this happens , " Peskin said , so human probably wo n’t be around to mind .
Plus , the position is n’t locked tight just yet . For one thing , the mass of the top quark is n’t acknowledge on the dot enough yet .
And furthermore , the whole Higgs instability scenario depends on there being no new corpuscle beyond the ones known now . Since many physicists suspect the population is actually rich with particles they have n’t yet discovered , such as the plethora of particles anticipate by thetheory of supersymmetry , the Higgs instability could be disputable .
" This notice is very interesting , but there ’s a big public debate about what it means , " Peskin told LiveScience . Some experts think that the fact the Higgs boson has the mass it does is because the universe truly is unstable .
" And there are other the great unwashed like me , who say it ’s just a curiosity and after we describe supersymmetric subatomic particle , mass will say it ’s entirely irrelevant , " Peskin enunciate . “We do n’t bang who ’s veracious , that ’s what ’s so beautiful about this . "
