Didn't the universe start out with a billion times more anti matter and matter particles than the remaining matter particles in the universe?
I do know. There were 1 billion times more anti-matter particles and 1 billion times more matter particles that annihilated each other than there is remaining matter particles.
It's mind boggling.
My understand is that the early universe was all energy ... and as the universe expanded and cooled ... matter condensed out of energy ... we can do this in a lab and we always get two particles ... an electron and a positron ... every ... single ... time ...
Assuming this was true in the early universe, and there's no reason to think otherwise ... then with our nice planet Earth made of matter, somewhere in the universe, there needs to be an antimatter Earth ...
Here's the Wiki article ... it is what it is I guess ...

ETA: For some reason, the 1.2 nm wavelength sticks in my mind ... weird ...
