It is often posed that Gravity is a universal constant.
Could Gravity share the same source?
Could Gravity share the same source?

After all it took about 300 years for us to accept that the world wasn't flat, after many folks knew it wasn't.
what makes gravity a universal constant then?Back on topic. Basicly this is another grand unification thread. I think we have enough of them as it is.
Perhaps there are new atoms to be found that is the expression gravity.
Chronos said:There may be only one fundamental force of nature. Current theory predicts the universe started out in a state of pure energy. As it cooled down, the four forces of nature gradually broke away from the unified force. The first to break free was gravity, after that came the strong force, followed by the electromagnetic and weak force. The question is why gravity, by far the weakest force, was the first to break away? Next to break free was the strong force. Then the EM and then the weak force. Weird.

The most common source of gravity is mass. Objects with mass create a gravitational pull towards them, which is what we experience as gravity on Earth.
The greater the mass of an object, the stronger its gravitational pull. This is why planets with larger masses, such as Jupiter, have a stronger gravitational pull than smaller objects like the Moon.
No, gravity cannot exist without mass. It is the mass of an object that creates a gravitational field, which then causes the force of gravity.
No, gravity is not the same everywhere on Earth. The strength of gravity varies depending on the distance from the center of the Earth and the mass of the objects around it.
In space, gravity still exists but it is much weaker compared to Earth due to the absence of large masses. Objects in space still have gravitational pull on each other, which is why planets and stars are able to orbit each other.
