Basically, or if it has different properties because of (anti)quarks resulting in different chemical compounds.


Another thing that might be interesting to look at is decay rate. We already know how normal mass does it's thing, but anti-matter seems to be for the most part "gone" from the Universe. The non-symmetry aspect of anti-matter will be a big thing in physics, in general, to understand.

So I may have answered my own question as I'm sure decay rates would certainly be an obvious thing to look at. If any of the fundamental forces are different, for example, you could have anti-matter out in space hiding from view in blackholes, etc...

Right now they're looking at dark matter being a sort of "condensed state" matter that "can't" react with anything but itself and weakly at that. Gravity as well (it looks like). Outside of this state we might find it a lot, but we do not understand the mechanism that created it or is creating it. Anti-matter was brought up in this argument. At some point after the big bang the anti-matter would have joined with particle "x" and became this condensed matter that basically has most of it's fundamental forces bound to itself. Therefore, unless this stuff breaks apart due to some process, we may never find it as it is essentially swept under the rug and we can't lift the rug.

Also from wiki:

The biggest limiting factor in the large scale production of antimatter is the availability of antiprotons. Recent data released by CERN states that, when fully operational, their facilities are capable of producing 10⁷ antiprotons per minute. Assuming an 100% conversion of antiprotons to antihydrogen, it would take 100 billion years to produce 1 gram or 1 mole of antihydrogen (approximately 6.02×10²³ atoms of antihydrogen).

(That's 7.2 times the age of the universe!)
