He also introduced the Dirac equation, combining Einstein’s special relativity with quantum mechanics, which predicted the existence of positrons (antiparticle ... electromagnetic force is the ...

A photon - a single bit of electromagnetic radiation - at sufficiently ... a positron and antiproton come into being. Most of these antiparticles are quickly swallowed up by the event that created ...

As the photino mirrors the properties of the photon, it must be its own antiparticle. Thus the photino is a Majorana fermion. So, for similar reasons, are various other superpartners (such as ...

Electromagnetic radiation is carried by photons, massless particles that travel at the speed of light (300,000 kilometers per second in a vacuum). Every photon is characterized by wavelength (the ...
