Interesting. But the antimatter still has a positive mass, yes?
Are they saying that there are antigravity galaxies? I mean, if antimatter is found only in the intergalactic void, wouldn't you expect to find galaxies and clusters of stars composed solely of antimatter? And if that's true (or even if antimatter is only found in the void), wouldn't it repel light away from it, effectively blinding us?
