eliminate the possibility of relatively large pockets of antimatter. Even if the ratio of anti-matter to matter is only 1%, that's one heck of a lot of anti-matter, including the possibility of entire stars/galaxies of the stuff.
For 1% antimatter, we'd expect to see huge energy bursts from regions where, for example, galaxies are colliding. I wonder if our astronomy is good enough to rule that out. I love the idea that some advanced civilization might be able to find an anti- star system somewhere and go harvest it for fuel. But it's so volatile that it's hard to imagine any of them being nearby.
