alt Hacker NewsSo, are you saying that it might be possible that there are antigalaxies somewhere out there beyond the visible horizon in spacetime ? I mean, of course “possible” like flying elephants possible, but maybe theoretically predictable?
Like maybe the matter went this way, and the antimatter went that way in spacetime? Or maybe all the antimatter went before the Big Bang and the matter went after?
I mean that’s wild but it would fix the symmetry problem!
I'm an amateur at best but I've only recently realised the implications of the observable universe, that is, we only know of the existence / size of the universe in what we can see, and there may be (and correct me if I'm wrong) way more Stuff beyond this 'boundary' whose light hasn't / will never reach us.
