In my opinion, antimatter will be the eventual solution to interstellar space travel due to its efficiency with regards to using small amounts of it to traverse through a large amount of outer space. At CERN they are able to produce several trillionths of a gram of antimatter at a cost of $20 million. Total worldwide production to date has been a few nanograms. Minuscule amounts produced at 10-12 kilograms can be compared to what physicist Michio Kaku refers to as Gerald Smith of Pennsylvania State University’s personal estimation that 4 milligrams of antimatter would take us to Mars (a milligram of antimatter is 10-6 kilograms). In terms of a size comparison we would need to move from production of antimatter from the size of a human cell to the size of a Mosquito. Kaku says that it is conceivable that if an atom smasher was built specifically just to produce lots of antimatter (current atom smashers have various purposes that are in demand) combined with mass producing these machines we could get antimatter production up significantly.
Antimatter is also the holy grail of some science fiction franchises. In Star Trek: the Original Series Engineer Montgomery Scott is always talking about various issues involving the antimatter and matter parts of the engineering portion of the star ship Enterprise. In terms of reaching those fantastical journey’s that the Enterprise takes on in a real life scenario (which could be possible near the end of this century) 100 grams of antimatter will perhaps take us to nearby star systems.
In terms of the origin of the term antimatter it was first predicted by Paul Dirac in 1928 with his Dirac equation and later discovered in 1932 by Carl Anderson. In 2018, CERN proposed a containment technology that would allow a billion anti-protons to be contained in a device that could be driven to other labs. Labs similar to CERN where antimatter has been produced include the Fermi National Accelerator Laboratory (pictured in the featured image of this article) in the United States.
