Based only on the latest measurement of the antiproton magnetic moment , the universe should n’t exist . The time value shows that protons and their antiparticles are adequate in everything but charge and they should have annihilated themselves in the first few instants after the Big Bang .

manifestly , there is a lot more to antimatter physics than just antiprotons , but this result tells us that the answer to why matter dominates in the universe wo n’t be discovered here . The finding , issue inNature , is 350 times more precise than theprevious one . This is the first fourth dimension that the incertitude of antiproton measurement is smaller than   it is for protons .

“ It is in all likelihood the first metre that physicists get a more accurate mensuration for antimatter than for matter , which demonstrates the extraordinary procession reach at CERN ’s Antiproton Decelerator , ” first - author of the work Christian Smorra , from CERN , said in astatement .

To perform the mensuration , the researchers had to store antiprotons in a Penning yap , a special machine that uses magnetic and electric field to keep charged particles from encountering matter and annihilating themselves . You would n’t be able to store antimatter in a regular container .

“ This effect is the culmination of many years of continuous research and development , and the successful mop up of one of the most difficult measurements ever performed in a Penning trap instrument , ” Stefan Ulmer , a representative for the BASE collaborationism , added .

The BASE collaborationism was also the team that find the most exact value for the proton magnetic moment in 2014 . If we were to base our interpretation of the universe on these measurements alone , we would have to reason out that our macrocosm could n’t exist . Matter and antimatter are exactly the same , absolutely symmetrical , and neither should have dominate at the dawn of time .

patently , the universe seems to care very little about our current ignorance , as well as how it exist , it has even hide what have this asymmetry . How antiprotons reply to a magnetic field of battle is one of the many avenues that physicists around the man have been look into to answer this enigma . Neutrino demodulator across the world and even the LHCb experimentation at CERN are all looking at potential sources of this asymmetry . subject clearly has something going on . We just have to feel it .
