And the most expensive substance in the world is: Antimatter priced at $62.5 Trillion per gram!
Antimatter is like the substance of the future.
Nowadays, it is one of the most difficult materials to produce.
Antimatter in the form of individual anti-particles, however, is commonly produced by particle accelerators and in some types of radioactive decay.
If we could find a less expensive way to produce antimatter, it could possibly fuel spaceships to the planets in a very distant future.
