> They measured that they needed a magnetic field bias applied to the anti-hydrogen equivalent to "pushing them up" with 0.75g (+/- 0.25g or so), so anti-matter is attractive. No new physics. That part bugged me a bit. Why 0.75g? Shouldn't we expect 1.0g? (Yeah, I know, +/- 0.25g...) Did I miss something, or is antimatter attracted less than regular matter?
