virtual pair								Particle and antiparticle that exist for an extremely short time, often as the intermediate stage of a nuclear transition. According to Dirac's theory, the vacuum can be visualized as consisting of a sea of virtual electron-positron pairs that can only be released or separated when sufficient energy is made available.	or center of gravity	inversely proportional to the wavelength	virtual particle	inversely proportional to its momentum			uncertainty principle
