What Produces Gravity??
What produces gravity?? Is there any specific theory for this?

cragar said:mass or energy bends space-time , a photon has a gravitational field
KingAntikrist said:What about the speculated gravitons? Don't they "produce" somehow gravity? (by existence of mass ofc).
nismaratwork said:Even if they exist, they would be the quanta of gravity, mediating interaction, not the cause. Photons are the quanta of the EM spectrum, but they do not "cause" it.
cragar said:Doesn't relativity say that gravity is a self interacting phenomenon ,
Is a graviton an excitation of the field , couldn't gravitons interact with each other ,
Isn't a gravitational wave affected by gravity .
cragar said:Why does every one spell my name crager and not cragar , I think there some threads that talk about gravitons interacting , Wouldn't a graviton posses energy .
so why wouldn't this energy be affected by other energy .

untiltwilight said:The graviton! Muah haha! Seriously...if it existed. Or at least if we could prove its existence. That seems to be the whole point to building the Large Hadron Collider.http://www.star-signs.org/compatible-star-signs.htm [Broken].to figure out and prove what keeps everything in place in the universe. :) A good way to do more research is to learn about the Large Hadron Collider and also to delve into the current String Theories.

In general relativity the components of the stress-energy tensor (or also called the energy-momentum tensor) determine the spacetime curvature of a point in spacetime. In general relativity gravity is not a force but instead expressed as curvature of spacetime.SaqibAhmed said:What produces gravity?? Is there any specific theory for this?
This link should help to explain the "relativity" aspect of what they are talking about in laymans terms. It's also fantastically entertaining to watch.SaqibAhmed said:What produces gravity?? Is there any specific theory for this?

Gravity is a fundamental force of nature that causes objects with mass to attract each other. It is the reason why objects fall to the ground and why planets orbit around the sun. According to Einstein's theory of general relativity, gravity is the result of the bending of space and time by massive objects.
The two main theories about the cause of gravity are Newton's theory of gravitation and Einstein's theory of general relativity. Newton's theory states that gravity is a force that acts between all objects with mass, while Einstein's theory explains gravity as the curvature of space and time caused by the presence of mass.
There is a lot of evidence that supports the theory of gravity, including the observations of the motion of planets and moons in our solar system, the bending of light by massive objects, and the existence of gravitational waves. Additionally, experiments such as Galileo's dropping objects from the Tower of Pisa and the Cavendish experiment have also provided evidence for the existence of gravity.
While there have been attempts to explain gravity using other forces, such as electromagnetism and the strong and weak nuclear forces, these theories have not been successful in fully explaining the phenomenon of gravity. Einstein's theory of general relativity is currently the most accurate and comprehensive explanation of gravity.
Gravity plays a crucial role in the formation and evolution of the universe. It is responsible for the formation of galaxies, stars, and planets. Without gravity, the universe would be a very different place, and life as we know it would not exist. Additionally, gravity also affects the expansion of the universe and the movement of celestial bodies within it.
