from the world's big
A new study rocks prevailing theories on antimatter in the early Universe.
- Scientists from around the world teamed up to study the properties of neutrons.
- They were able to achieve extremely precise measurements of electric compasses in neutrons.
- The results challenge current theories of why antimatter and matter didn't destroy each other in the early Universe.

BASE particle physicists have discovered a very precise way to examine antimatter.
Thank your lucky stars you’re alive. It’s truly a miracle of nature. This has nothing to do with spirituality or religion and everything to do with science. Life itself may not be the miracle. Although we haven’t found it elsewhere yet, our galaxy alone is so replete with Earth-like planets that, mathematically speaking, one of them must hold life, even if it’s just the microbial variety. Intelligent life may be another matter.
Scientists work out methods for finding the difference between the magnetic moments of protons and antiprotons and see that they’re the same.
Why are we here, anyway? No, not in the what’s-the-meaning-of-it-all sense, but why haven’t matter and antimatter completely obliterated each other, the universe and us? In nature, two identical things that are 180° out of phase with each other — as matter and antimatter seem to be — cancel each other out. So, um, why are we here?
CERN researchers make a major step in understanding antimatter by trapping antihydrogen atoms and controlling them with lasers.
Antimatter is a concept that oozes sci-fi, evocative of amazing engines, time travel and most likely destruction of the whole universe. Or maybe it’s a parallel-worlds-are-everywhere-around-us type of thing. In any case, this idea comes to us from the law of physics that predicts that there should be an antimatter particle for every particle of regular matter. But if the two shall ever meet, there’d be a release of energy, annihilating both.
