Do you have to have mater for the gravity field,or is gravity a thing that has all ways been.
In General Relativity, the stress-energy tensor (which includes energy and momentum) is the source of gravitational effects. This does not require that the energy is in the form of matter.wolram said:Do you have to have mater for the gravity field
I'm not quite sure what you are asking there. The gravitational effect of some amount of energy around a given location is similar regardless of its form, so there's no change when a given amount of radiation energy is converted to or from the corresponding amount of matter.wolram said:or is gravity a thing that has all ways been.

The current understanding of gravity is based on Einstein's theory of General Relativity, which states that gravity is not a force between masses, but rather a curvature of spacetime caused by the presence of mass and energy.
Yes, according to General Relativity, gravity is dependent on the presence of matter and energy. The more mass and energy an object has, the stronger its gravitational pull.
General Relativity explains that mass and energy cause spacetime to curve, and objects with mass will follow the curvature of spacetime, resulting in what we perceive as gravity.
Yes, there are other theories such as Newton's theory of gravity, which explains gravity as a force between masses. There are also theories that attempt to reconcile General Relativity with quantum mechanics, such as string theory and loop quantum gravity.
Yes, there is strong evidence to support General Relativity's explanation of gravity. For example, the bending of light around massive objects, known as gravitational lensing, has been observed and can only be explained by the curvature of spacetime. Additionally, the predictions of General Relativity have been confirmed through numerous experiments and observations.
