Does gravitational waves participate in gravitation interaction?

In summary, gravitational waves carry energy and can participate in gravitation interaction, being deflected by massive objects such as the sun. In the weak field, they can be approximated as having an "effective stress-energy tensor" and their deflection by the sun is negligible. In the strong field, they are viewed as geometry and arise naturally from the nonlinearities in Einstein's field equations. However, both approaches give similar empirical results in the appropriate regions.

Does gravitational waves participate in gravitation interaction??

Does gravitational waves participate in gravitation interaction??
When gravitational waves pass through the sun ,it will deflect??

Thank you in advance!

Gravitational waves carry energy, as per the http://en.wikipedia.org/wiki/Sticky_bead_argument"

In weak field gravity, one can consider gravity waves to have an "effective stress-energy tensor". This effective energy can't be precisely located, but can be averaged out over a wavelength. While this is only an approximation, it gives the best understanding of how gravity waves act in the weak field. Our solar system, including the sun, is "weak field" as far as GR goes. Thus, gravity waves will be deflected by the sun in the same manner that light will. Since gravity waves have momentum, the sun should also move when the gravity waves are deflected, but in the case where the weak field approximation applies this deflection is negligible and can be and is usually ignored.

In the strong field, gravity waves aren't explicitly included in stress-energy tensor. Instead they arise naturally from the nonlinearites in Einstein's field equations. Thus in the strong field, gravity waves are viewed as geometry, rather than energy. Of course the weak field and the strong field approaches give approximately the same answer empirically in the region where the weak field approximation is justifiable.

Related to Does gravitational waves participate in gravitation interaction?

1. How do gravitational waves affect the gravitational interaction between objects?

Gravitational waves do not directly affect the gravitational interaction between objects. They are a result of the acceleration of massive objects, such as black holes or neutron stars, which can cause ripples in the fabric of space-time. These waves travel at the speed of light and carry energy, but they do not directly participate in the gravitational interaction between objects.

2. Can gravitational waves cause objects to attract or repel each other?

No, gravitational waves do not cause objects to attract or repel each other. The force of gravity is caused by the mass and distance between objects, and gravitational waves do not change this fundamental interaction. However, the energy carried by gravitational waves can cause objects to move slightly as they pass through, which can be detected by sensitive instruments.

3. How are gravitational waves detected?

Gravitational waves are detected using highly sensitive instruments called interferometers, which measure tiny changes in the distance between two points caused by the passing of a gravitational wave. These instruments use lasers and mirrors to detect the stretching and squeezing of space-time caused by the wave.

4. Can gravitational waves be produced artificially?

Yes, gravitational waves can be produced artificially by colliding massive objects, such as black holes, in a controlled environment. This is currently being done in experiments to better understand the properties of gravitational waves and their effects on space-time.

5. How do gravitational waves relate to Einstein's theory of general relativity?

Gravitational waves were predicted by Einstein's theory of general relativity, which describes gravity as the curvature of space-time caused by the presence of mass. According to this theory, accelerating masses can cause ripples in space-time, which we now know as gravitational waves. The detection of these waves has provided strong evidence for the validity of Einstein's theory.
