Here is why their team finds this significant:

“This is an important issue,” says Stefan Ulmer, who led the research, “because it helps us to understand why we live in a universe that has practically no antimatter, despite the fact that the Big Bang must have led to the creation of both.

(once again it should be noted that many astronomers and astrophysicists no longer believe in the big bang theory)

The Big Bang singularity is the most serious problem of general relativity because the laws of physics appear to break down there,” Ahmed Farag Ali at Benha University and the Zewail City of Science and Technology

That being said, this is still an interesting finding.

And below is a related video explaining antimatter which is especially relevant to the findings noted above.
