Carl David Anderson proved the existence of antimatter at the California Institute of Technology in 1932, when he discovered the positron.

In 1996 physicists using the particle accelerator at CERN in Geneva, Switzerland, created the first atoms of antimatter: nine atoms of antihydrogen survived for 40 nanoseconds (40 billionths of a second).

The Alpha Magnetic Spectrometer was flown on the space shuttle Discovery in June 1998, searching unsuccessfully for antihelium and measuring the energy spectra of positrons and antiprotons.

In August 2011 scientists analyzing data from the satellite PAMELA confirmed that a plasma belt surrounding Earth contains antimatter.

1 Gram of Antimatter costs approximately 62 trillion dollars.
