    Assuming an optimal conversion of antiprotons to antihydrogen, it would take two billion years to produce 1 gram or 1 mole of antihydrogen (approximately 6.02×10-23 atoms of antihydrogen).

    Antimatter is said to be the most costly substance in existence, with an estimated cost of $25 billion per gram for positrons[17], and $62.5 trillion per gram for antihydrogen.
