It seems that the most precious substance in the world is "antimatter. | 世界で一番貴重な物質は「反物質」らしい。

反物質 は、ある物質と比して質量とスピンが全く同じで、構成する素粒子の電荷などが全く逆の性質を持つ反粒子によって組成される物質。 例えば、電子はマイナスの電荷を持つが、反電子(いわゆる陽電子)はプラスの電荷を持つそうなのですが反物質の価格は1g7062兆円らしい。反物質は作ることはできないんだけど反物質を構成する素粒子(反粒子)を加速器を使って人工的に作ることが可能らしい。

Antimatter is a substance composed of antiparticles that have exactly the same mass and spin as a certain substance, but whose constituent elementary particles have completely opposite properties, such as electric charge. For example, electrons have a negative charge, but antielectrons (so-called positrons) have a positive charge. Antimatter cannot be created, but it is possible to artificially create the elementary particles (antiparticles) that make up antimatter using an accelerator.
