General Relativity is assuming the existence of a metric everywhere, in someway depending directly or not on the repartition of the energy. Must I understand this assumption as equivalent to the existence of a background geometric field ?(adsbygoogle = window.adsbygoogle || []).push({});

The satellite Gravity Probe B is actually testing the Thirring Lense effect. If one find a positive answer, does it mean that this geometric field is evoluting for itself, in some way not totally depending on the manner that the earth is turning around the sun but quite more in dependance with all events happening somewhere in the universe ?

If the answer is yes, does it mean that the red shift could have an other explanation as the expansion; something like a Doppler effect due to the difference between the speed of the matter and the speed of the field where this matter is moving in?

Sorry if my question is stupid or not clear enougth: It is not easy to explain and I will try again in accordance with your questions. Thanks. Blackforest
