Why Isn’t There Antimatter in Our Universe?

By , in News Sci/Tech on . Tagged width: ,

Over time, people have wondered why do we exist, how did it all happen and why is our Universe full of matter, and not so much of antimatter.

Well, when the Universe was young, almost all the antimatter vanished, and all that remained was the matter. Scientists have looked for the answer for so long, and they have also looked for ways to test the theories through experiments.

Three theorists have talked about a trio of particles, which is called Higgs bosons, which could be the reason behind the disappearing of antimatter in the Universe. They also know how to find the culprits.

What’s with the missing antimatter?

For every interaction between the subatomic particles, the antimatter – that’s quite identical with the ordinary matter, but it’s different when it comes to charge – and the matter is produced equally. This means there’s a symmetry in the Universe. But we don’t see the antimatter whatsoever. According to scientists, for every particle of antimatter that exists, there are a billion of particles of normal matter – in the entire cosmos.

It has multiple names, like the baryon asymmetry problem, or the matter asymmetry problem. The name is not that important, considering the fact that it has scientists blocked. No one is able to come up with a valuable explanation of why there’s so much matter and so little antimatter in the Universe. And since scientists are supposed to find that out, and they don’t have an answer, it’s quite annoying.

But nature did help us by leaving some clues here and there. Let us take a clear example: the evidence for the antimatter appears in the cosmic microwave background, which is basically heat that’s leftover from the Big Bang.
