Part of me is still half-convinced that there are whole galaxy clusters of antimatter that are simply too far away from other clusters to produce any noticeable gamma rays, and the reason they didn’t interact near the beginning of the universe is the same reason the whole thing didn’t collapse into a super massive black hole: we don’t know yet, but probably along the same lines as dark energy. A lot of it did probably interact though and that’s where a lot of the CMB comes from.
I’m definitely a lay person though, I’m sure an actual physicist can tell me that’s definitely not the case, I just don’t know why not yet.
And 30 years after LASIK, you’d be incredibly lucky if your eyes hadn’t gotten worse to the point you’d need glasses anyway.
