Encore un article passionant qui m'a pas du tout donnée mal à la tête ;)
Finally this has the consequence that there may be some anti-us deeper in the universe made of antimatter.
The day we want to make an exchange with them, we have to worry/agree on what we call matter and antimatter so as not to make a mistake with catastrophic consequences (Ok celle là l'ai piqué à Etienne Klein de mémoire hahahaha)
Merci pour ton commentaire!
Unfortunately, the observations do not seem to agree with this statement. I think that the fraction of antimatter regions in the universe is below 0.01%. So not too much worries for now :)
