Scientists at CERN, the European Organization for Nuclear Research, have said that our Universe should not exist. But why?
CERN’s latest study find out that there’s a perfect symmetry between matter and antimatter but one thing is still unclear: why they didn’t annihilate each other upon the birth of the universe.
“All of our observations find a complete symmetry between matter and antimatter, which is why the universe should not actually exist,” says Christian Smorra, a physicist at CERN’s Baryon–Antibaryon Symmetry Experiment (BASE) collaboration. “An asymmetry must exist here somewhere but we simply do not understand where the difference is.”
When born, the universe had equal amounts of antimatter and matter, but each antimatter particle should have canceled out its corresponding matter particle, leaving nothing behind. Guess what? It did not happened.
Antimatter is notoriously unstable – any contact with regular matter and it annihilates in a burst of pure energy that is the most efficient reaction known to physics. That’s why it was chosen as the fuel to power the starship Enterprise in Star Trek. (Cosmos Magazine)
Scientists say it’s not clear yet how the universe works and they are also thinking that antimatter has a reversed gravity effect, fact that kept everything alive until now. There will be further examinations on anti-protons and not only, hoping to find a difference in their behaviour to those regular protons.
“This result is the culmination of many years of continuous research and development, and the successful completion of one of the most difficult measurements ever performed in a Penning trap instrument,” says Stefan Ulmer, spokesperson BASE Collaboration.
