Antimatter, composed of antiparticles, has the potential to revolutionize energy production, propulsion, and other applications due to its highly efficient energy release upon contact with matter. However, producing antimatter on a large scale has proven to be a significant challenge.

Resolution criteria:

This question will resolve to "YES" if, before January 1st, 2040, a substantial amount of antimatter (specifically, at least 1 gram) is publicly and credibly documented to have been manufactured worldwide within a one-year period. The antimatter can be in the form of any antiparticle, such as antiprotons, antineutrons, or positrons.

I will use my discretion when resolving this question, possibly in consultation with experts.
