the universe's evil twin, born equal then mysteriously vanished, leaving us alive by accident
means Matter made of particles with the opposite electric charge and quantum properties to ordinary matter, which annihilates in a burst of energy when it meets its normal counterpart.
from A 20th-century scientific compound, simply 'anti-' (Greek for 'against, opposite') bolted onto 'matter.' The idea arrived before the name: in 1928 physicist Paul Dirac's equations predicted a mirror-image electron, and when the positron turned up in 1932 the prediction held. 'Anti-' traces to Greek 'anti,' meaning 'opposite' or 'in place of' — the same prefix lurking in antidote and antonym. 'Matter' comes through Old French from Latin 'materia,' originally 'wood' or 'timber,' the stuff a thing is built from.
- price tag
- Antihydrogen would cost about 62 trillion dollars per gram
- annihilation
- Meets matter, both vanish into pure energy instantly
- missing mystery
- Big Bang made equal amounts; antimatter mostly disappeared
- bananas emit it
- Bananas release a positron roughly every 75 minutes
- already stored
- CERN has trapped antihydrogen atoms for minutes
