# So what's the currently accepted gravity theory?

• Sariaht
In summary, the conversation discusses the equations and validity of Einstein's Field Equation, as well as the direction of vectors and the variation in gravity. The conversation also mentions resources for further understanding of general relativity.

How does it work, what are the equations, are they valid, from what matrix {}, if such, were they derived? And how high level are the physics?
Where does the force come from ie what direction has the vektors? What cause the variation in gravity that I have read about?

I read the first gravity part, just wondering, in plain english, where the proportionalities are derived from? Perhaps if you would do the thread the honor of through the circumstances themselves derivate G?

There are several GR texts on the web. Waner or t'Hooft for example. See the same Baez site for links:

There are also videos of 3 1-hour lectures by Sean Carroll.

## 1. What is the currently accepted gravity theory?

The currently accepted gravity theory is Einstein's theory of general relativity. It describes gravity as the curvature of spacetime caused by the presence of matter and energy.

## 2. How does general relativity differ from Newton's theory of gravity?

General relativity differs from Newton's theory of gravity in that it takes into account the curvature of spacetime, while Newton's theory describes gravity as a force between massive objects.

## 3. Has general relativity been proven to be true?

General relativity has been extensively tested and proven to be true in many different situations, such as the precession of Mercury's orbit and the bending of light around massive objects.

## 4. Are there any challenges or limitations to general relativity?

While general relativity has been successful in explaining many phenomena, it is not compatible with quantum mechanics and does not fully explain the behavior of gravity at very small scales. This has led to ongoing research and attempts to reconcile these two theories.

## 5. Is there any evidence for alternative theories of gravity?

While there have been attempts to develop alternative theories of gravity, such as modified Newtonian dynamics and string theory, there is currently no strong evidence to support these theories over general relativity. General relativity remains the most widely accepted theory of gravity among scientists.
