Antimatter More Vulnerable to Gravity, Says CERN
A team of researchers from CERN said recently it probably has found clues that suggest that antimatter is subject to the antimatter forces.
Antihydrogen Laser Physics Apparatus (ALPHA) was used to obtain the first measurements of the effect of gravity on the antimatter equal to hydrogen. It is being said that the antimatter-related mysteries and the query whether the same fell up or down might help determine a strangest enigma of physics.
It could probably uncover the reason why more matter is contained by the universe than antimatter. As per the findings, positrons and antiprotons as well as mirror-images of ordinary protons and electrons and quantum "spins" are all captured by ALPHA.
Particle physicists are of the view that during the Big Bang, matter and antimatter might have been contained by the cosmos in the same proportion. Nonetheless, they could have destroyed each other, thereby leaving photons only along with an empty universe.
Flashes of light were observed by the CERN team during annihilation of matter and antimatter particles by each other. Location and time of the flashes was measured then. It was noted that antimatter was more susceptible to gravity by 110 times.
"We've taken the first steps toward a direct experimental test of questions physicists and nonphysicists have been wondering about for more than 50 years. We certainly expect antimatter to fall down", said the University of California, Berkeley's physicist and ALPHA team member, Joel Fajans.
