1) Antimatter

Cost: $100 Trillion/gram

It is the most interesting and most expensive material on earth. In physics, particles make up materials. Similarly, antiparticles make up antimatter. For example, there is antiproton for proton; there is antineutron for neutron. The antimatters are extremely hard to make and catch. Antimatter is also created in a very small amount in particle accelerators like at CERN. Cosmic ray collisions and radioactive decay also crate them in small amounts in the universe. Tracing antimatter is also very hard and needs a lot of sensors.

A proton has a positive charge in common knowledge, and the electron has a negative charge inside an atom. Antiproton also has a negative charge but the same mass as the proton. So Antiproton is the antimatter to Proton. In theory, the collision of particles and antiparticles can cause annihilation.
