While we are on this subject I have a question for some of you smart guys out there.
With reference to the Einstein Field Equations:
1. Do solutions of these equations exist that predict Gravity Waves?
2. Are approximations required to achieve these solutions?
3. Are the solutions rock solid or could they be challenged?
The reason for questions:
We’ve never seen a gravity wave. Not one. So I’m interested in how accurately we believe we can predict the magnitude of the disturbance required to create a gravity wave detectable on earth.
Some scientists believe gravity is really a bend in space time, similar to a mass on a rubber mat attracting smaller masses that circle it.
I am not a Theoretical Physicist, but I play one on FR.
Here is how you observe a Gravity Wave:
Choose a star of sufficient magnitude and distance that you can get a continuous observation of its light spectrum 24 hours a day. Obviously this must be done via satellite like the Hubble Telescope.
Monitor and constantly record the magnitude of the red shift of the dark line of a common element in the star’s spectrum.
The magnitude of the red shift should remain constant.
If it changes during the monitoring and recording process, a gravity wave must have passed thru between the star and your observation point.
