The Costliest Substance Known
Antimatter’s $62T/gram price reflects its rarity and production challenges.
Antimatter, the most expensive substance, costs ~$62 trillion per gram, per a 1999 NASA estimate by Harold Gerrish, based on production energy and infrastructure costs.
It annihilates matter on contact, releasing pure energy, making it a potential fuel for spacecraft or medical uses.
Only nanograms have been produced, as cosmic rays create it rarely, and Earth’s atmosphere destroys most antiparticles.
