i wonder whether an electron is absorbing virtual photons because it is in a electromagnetic field, would that mean that it would change its angular momentum by hbar?

Virtual particles are particles that are thought to exist temporarily as a result of the uncertainty principle in quantum mechanics. They are not observable directly, but their effects can be seen in the behavior of other particles.
Virtual particles interact with other particles through the exchange of force-carrying particles, such as photons or gluons. This interaction is known as the virtual particle exchange force.
No, virtual particles cannot be observed directly as they have extremely short lifetimes. However, their effects can be observed through experiments and calculations in quantum mechanics.
In the vacuum of space, virtual particles are constantly being created and annihilated due to the uncertainty principle. This creates a fluctuation in the energy density of the vacuum, known as vacuum energy.
Virtual particles do not play a significant role in our everyday lives as their effects are only noticeable at the subatomic level. However, they are crucial in understanding the behavior of particles and the fundamental forces that govern our universe.
