Question

Quizplus · Accepted Answer

A virtual particle is a particle that exists for such a short time interval that we cannot detect it by direct measurement. They are fundamental constituents of the quantum field theory and play a role in the calculations of physical interactions between particles. However, unlike real particles, they do not exist as independent entities with a definite location and momentum.
