Physics
  • Molecules formed by atoms consisting of antiprotons, antineutrons, and positrons. Stable antimatter does not appear to exist in our universe.

    ‘In the enormous densities of the early moments of the Big Bang the result would have been a catastrophic annihilation of matter and antimatter into radiation.’
    • ‘There is both matter (such as electrons) and oppositely charged antimatter (such as positrons).’
    • ‘Paul Dirac predicted the existence of antimatter with his relativistic wave equation in 1928.’
    • ‘He also predicted the existence of antimatter (specifically the antiparticle of the electron) that was later discovered in nature.’
    • ‘This brief survey of recent Lorentz tests only lists those experiments involving light, ordinary matter, and antimatter.’
    • ‘The definition of matter and antimatter is purely conventional.’
    • ‘Theory suggests that, at the moment the universe was created, equal amounts of matter and antimatter were formed.’
    • ‘What is CP violation and how does it explain the fact that matter outnumbers antimatter in the universe?’
    • ‘Matter and antimatter just don't mix, so it's surprising that you can probe one with the other.’
    • ‘Why is the universe made of matter and not equal parts of matter and antimatter?’
    • ‘Various propulsion schemes have been proposed, from nuclear fusion to antimatter to laser sails.’
    • ‘When particles of matter and particles of antimatter collide, large amounts of energy are produced as a by-product.’
    • ‘You wouldn't be able to tell by looking whether the black hole was originally formed by matter, antimatter or green cheese.’
    • ‘Those equations and present particle physics say that matter and antimatter are equivalent.’
    • ‘The answer to your question is, thus, clearly yes: matter would be created when antimatter particles collide at high energy.’
    • ‘He saw how magnetic traps could make antimatter useful in medicine, principally in tumor treatment.’
    • ‘If matter and antimatter collide, they annihilate each other.’
    • ‘What everyone actually needs here is a more efficient mobile power source, whether it be cold fusion, lithium air or a matter / antimatter reactor.’
    • ‘Much like matter and antimatter the two objects would be almost instantly converted to pure energy, generating a massive explosion.’
