But while the virtual particles are briefly part of our world they can interact with other particles, and that leads to a number of tests of the quantum-mechanical predictions about virtual particles.

But virtual particles, or at least the net effect of them, really can be detected, at least indirectly. One of the most famous measurements supporting the idea that virtual particles really are ...

More the virtual particles present in empty space, their presence is necessary to predict, quantitatively, the effects that quantum fields have on observable quantities in our Universe.

Virtual particles and the quantum foam are one of the craziest of the quantum phenomena. They have no classical analog and they certainly seem like something that physicists dreamed up to save ...

A new Oxford study shows how physicists made light emerge from “nothing,” offering rare insight into the hidden energy of ...

There may be an infinite amount of energy locked in the vacuum of space-time. So could we ever harness this energy for ...

Physics Why virtual particles don’t exist but do explain reality – for now. So-called virtual particles aren't particles at all. Some argue that they are merely mathematical figments, and that ...

Virtual particles can have surprising physical effects on larger scales. One astonishing consequence is the Casimir effect. Place two uncharged metal plates extremely close together in a vacuum, ...

Determining this value as accurately as possible would help physicists nail down exactly which virtual particles are toying with the electron’s magnetic moment—some of which might belong to a ...

Physicists think that the “virtual particles” that pull at a muon’s g do so with different forces. Some particles yank with electromagnetism, whose influence is easy to calculate.
