It is often posed that Gravity is a universal constant.
Could Gravity share the same source?
Mass maybe? Matter is the souce...
I was referring to a common source, one shared by all matter.......
The link to this common source would have to be instanteous, yet gravity has been measured as propogating at the speed of light.
If there was a common source, it would take billions of years to communicate from one side of the universe to the other, by which time everything has moved around a bit.
The lowly photon is the source of gravity.
Photons have gravitational attraction for other photons. If, as Einstein thought, the final irreducible constituent of all physical reality is the electromagnetic field, then you have gravity built in.
Takes a while for everyone to get on board. It's been about a hundred years since Einstein's assertion was published, maybe in another hundred years it will be accepted. After all it took about 300 years for us to accept that the world wasn't flat, after many folks knew it wasn't.
Keep on chuggin !!
Actually many cultures have always thought the world was a sphere. Most people though out histroy didn't think the world was flat at all! Take ancient Hebrews for example who knew the world was a sphere.
Back on topic. Basicly this is another grand unification thread. I think we have enough of them as it is.
what makes gravity a universal constant then?
How is it that through out the universe gravity is constant and common? How is this achieved?
Perhaps there are new atoms to be found that is the expression gravity.
Ok....for the sake of discussion let's call it the 'g' particle.
possibly there exists only one 'g' particle that exists in all matter. zero dimensional. Say the only difference between the 'g' particle and other particles is 'time'.
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.
How can energy cool down ?
For something to cool down, it must give up some of its energy. If all it comprises of is energy, then the act of cooling down is in fact giving off energy, or the energy being dispersed.
If, in the beginning, there was only energy, then how does something other than energy - the four forces - break away from it ?
It can't because they don't exist.
More likely is that at the exteme pressure/concentration of energy in the beginning, no forces/relationships between the energy could be maintained. It was only at the edges of the concentration where the energy began to disperse that the simplest of the relationships/forces could be maintained - gravity.
As the energy continued to disperse, so more complex relationships could be established.
The common denominator regarding gravity relates to universal velocity of the atomic mass, (I think this is the possible answer you where looking for) all atomic matter is in motion for a very good reason.
Please go to the thread I started which is about atomic universal velocity and gravity under the Theory development header, I would be interested in your comments.
In the same sense that you need three minimum paramiters to gauge where you are in Spacetime X..Y..Z, Gravity cannot be a singular quantity, every single 'thing' that exists needs to be acted upon by at least THREE energetic quantities, this conspires to produce Gravitational effects.
