RE: Matter and Antimatter – An Explosive Couple! (Particle Physics Series – Episode 4B)
Great post. Upvoted and followed.
I recently watched a FermiLab youtube video on antimatter and why it is missing from the universe.
A better question is why didn't matter & antimatter just annihilate each other with 100% completion.
Would love to hear your thoughts on this.
Yet, particle physicist are not in front of a white page here. There are some particle physics reactions that do not seem to be perfectly "symmetric", i.e. that appear to favor slightly matter over antimatter. These reactions are under deep study .
I am currently reflecting on the next episode, that should enlighten you (yes a full episode on this question :-)! I will discuss the first instants of the universe, where matter and antimatter were formed.
Then, I will introduce a really important pillar in physics: the CPT theorem, and briefly mention some of the reactions that appear to violate it in favor of matter.
So stay tuned!
We are still working hard to answer this question. This is one hot topic in particle physics and there is for the moment no answer to it (but plenty of different options are available explaining why matter is dominating today).
