I think you show really well how tricky anti-matter is, almost mystical. I think it's more probable that anti-matter doesn't exist, given how reactive it is with regular matter. So Einstein's theory could be the right one. Unless something much weirder is going on.

And bravo for them imgs you made! Wish I could illustrate as well as you!
