Sorry if this is a basic question, or there is a glaringly large hole in my reasoning, I am not smart, and saw a documentary and did some googling, after which I decided to ask people with actual experience.
I read about the Big Bang resulting in a lot of matter and antimatter, and if we added it all up, it should equal 0, which is what there was before.
By this reasoning (matter and antimatter cancels out), could we add matter and antimatter? 0 + (-x) + (+x) = 0, and if we managed to separate the two (using gravity, maybe), could we end up with extra matter, but also extra antimatter, which can be ejected into space (or somewhere else, like another planet, where it will not affect us), we could end up with more stuff on Earth, but less stuff elsewhere.
Some issues with what I have just described:
We might not be able to siphon the antimatter and matter away from each other (or control anything about this at all).
I also heard that when antimatter and matter combine, it releases energy in the form of light. I feel like this violates the conservation of energy. If (-x) + (+x) = 0, I do not see where the light came from, unless there is some kind of negative energy released, like anti-light or something like that.
Also, somewhat related– CERN says there is some kind of matter-antimatter imbalance.
How plausible is what I have just described? Please, no hate or rude comments, I have no idea about anything physics-related (I am a minor and know next to nothing). If what I have described is not possible, could you provide a quick explanation (antimatter is a hoax, etc). I am not concerned with the fact that we have no technology to do this yet; I was curious as to whether such a thing could be possible.
If any of my facts or assumptions are wrong, kindly tell me.
