Is there such a thing as a spatial field containing energy or mass? How do you bend something without either?

Duhoc said:I think general relativity describes the curvature of space time.
Information, I thought, follows a straight path, which is in fact a curvature of space time.
I believe the paradox of force at a distance was what general relativity was designed to resolve.
Duhoc said:... if spacetime is curved it must have a physical nature because only a physical think can curve.
No, it doesn't. There are several misconceptions here.Duhoc said:There is obviously a distinction between space and space time. But even so, if spacetime is curved it must have a physical nature because only a physical think can curve.
You are conflating two very distinct concepts here, gravitons and gravitational waves. Gravitons are hypothetical particle that might arise in quantizing gravity. Gravitational waves are a consequence of general relativity, which is not a quantum theory. Gravitational waves and gravitons are distinct concepts.Duhoc said:part of the problem detecting the graviton is the amount of energy required to produce gravitons is projected to be far higher than we can currently produce at any LHC and probably be out of our reach for quite some time. The mere fact we haven't observed a graviton does not discount its possibility.
Physicists developed a quantum theory of electromagnetic radiation during the first half of the 20th century. There is no quantum theory of gravitation. "Quantizing gravity" is a shorthand term that means developing a working theory in which gravitation is described as a quantized interaction at the atomic scale.what precisely do you mean by "quantizing" gravity.
When we say that space "curves", we are referring to the concept of spacetime curvature, which is a fundamental concept in the theory of general relativity. This refers to the idea that objects with mass or energy can cause the fabric of spacetime to bend or warp, altering the path of other objects moving through it.
According to general relativity, gravity is not a force between masses, but rather the result of the curvature of spacetime caused by those masses. The more massive an object is, the more it warps the fabric of spacetime, causing other objects to follow a curved path around it.
Yes, we can observe the effects of spacetime curvature in various phenomena, such as the bending of light around massive objects like galaxies and black holes. This effect is known as gravitational lensing and has been confirmed by multiple observations and experiments.
Yes, the curvature of spacetime affects the motion of objects by altering their paths. This is why objects in orbit around a massive body, such as planets around the sun, follow curved paths instead of straight lines.
No, the curvature of spacetime can vary in different regions of the universe, depending on the distribution of matter and energy. In some areas, the curvature may be more pronounced, while in others it may be relatively flat. This is known as the curvature of the universe and is still a topic of ongoing research and debate among scientists.
