I wouldn't call Hawking radiation "matter," but okay.
edit: Oh, we're talking about matter in the halo.

So 2 billion years, assuming we solve the storage problem. Well, now I know that.

Their quark composition. An up and two downs, vs an anti-up and two anti-downs. In both cases, their fractional electric charges cancel out.

There's absolutely no difference in mass or gravitational effect.

Another fun fact: Antimatter costs over $70 trillion per gram.
Now here's a fun question: how long would it take us to produce 1 gram of antimatter at current production levels?

Yup, that's why I made an edit.
