Antimatter,catalogued.
An independent, sourced directory of every antimatter experiment, facility, record, paper and person, from Dirac's equation to antiprotons carried by truck.
Your cursor is an alpha source. Click to annihilate an antiproton.
Antimatter is routine to make and almost impossible to keep. One laboratory on Earth slows antiprotons enough to catch them, and it is switched off until at least 2028. A few groups hold antiprotons in traps, and in 2026 ninety-two of them were driven across a site and arrived. Most of the measurements proposed for it need less than a picogram.
From one antiproton to one gram.
Explore the scaleBlue marks are applications sized by Antimatter, Inc.; everything left of one picogram is a measurement, not a fuel.

Few people have ever built an antimatter trap. The field needs more.
Antimatter needs accelerator physicists, cryogenic and vacuum engineers, plasma physicists, detector builders and people who model all of it. The directory lists the groups doing the work, and who is hiring.
