And not antimatter; it still has a positive energy density. They call it 'exotic' matter for a reason; nobody has ever seen any.
In 1995 CERN announced that it had successfully brought into existence nine antihydrogen atoms by implementing the SLAC/Fermilab concept during the PS210 experiment.
I'm here to burst the warp bubble.
This all depends on a negative energy density to work.
cientists claim antimatter is the costliest material to make. In 2006, Gerald Smith estimated $250 million could produce 10 milligrams of positrons (equivalent to $25 billion per gram); and in 1999 NASA gave a figure of $62.5 trillion per gram of antihydrogen. This is because production is difficult (only a few antiprotons are produced in reactions in particle accelerators), and because there is higher demand for the other uses of particle accelerators. According to CERN, it has cost a few hundred million Swiss Francs to produce about 1 billionth of a gram (the amount used so far for particle/antiparticle collisions)
