At any given time, lots of them exist. I would expect this to produce a constant but rapidly changing gravitational force. How is this effect taken into account in cosmological theories?
kttuan said:1. I don't clear what you want to do but
2. There are two kind of "virtual" particles in physics concept:
- one is pseudo particles: particles stand for an energy state (vibration states in material, for example)- this kind does not cause a graviational field
- The second kind: virtual prticles which exist in a short time: in principle, this kind will cause gravitation.

Virtual particles are particles that are constantly popping in and out of existence in the quantum vacuum. They are not measurable and only exist for a very short period of time before disappearing again.
Virtual particles do not produce a gravitational force on their own. Instead, they are considered to be a manifestation of the quantum fluctuations of the underlying gravitational field. These fluctuations can interact with other particles and produce a gravitational force.
The gravitational force produced by virtual particles is extremely small and is only significant at the quantum level. It is not noticeable on a larger scale and does not contribute to the overall gravitational force between objects.
No, virtual particles cannot be detected directly. They are too short-lived and do not interact with other particles in a way that can be measured. However, their effects can be observed indirectly through their interactions with other particles.
No, virtual particles do not play a role in the curvature of space-time. This is a larger-scale phenomenon that is described by Einstein's theory of general relativity. Virtual particles only exist at the quantum level and do not affect the overall structure of space-time.
