virtual particle
Fleeting quantum fluctuation
A virtual particle is a theoretical particle that exists only momentarily during quantum interactions, mediating forces between other particles.
Unlike real particles, virtual particles cannot be directly observed—they "borrow" energy briefly in ways that would otherwise violate conservation laws.
The electromagnetic force between electrons is explained by the exchange of virtual photons.
The concept is central to quantum field theory, though physicists debate whether virtual particles represent physical reality or are merely mathematical tools.
