What is gravity -- really?
« on: 13/01/2014 21:10:22 »
I look up Gravity on the Internet and all I ever get is a picture of a big sphere on a sheet of rubber, and a smaller sphere being rolled into the big sphere. That doesn't really explain how gravity works and what is the 'force'.
I prepared a simple explaination of my understanding  of gravity and what causes it.
See my video at     


I would welcome any comments from the scientific community -- Is my idea correct, and is it new?
Thanks for your attention.

If gravity is really mediated by Gravitons there are two convincing arguments for them being able to travel faster than the speed of light i.e the geometric one that the planets could not stay in orbit if there was a delay in the Suns gravitation pull and the ability to escape from the singularity of a black hole thru the event horizon.
GR has the answer that there is no pull of gravity only a distortion of space-time hence no need for Gravitons else we are told that all will be revealed once a QM theory of gravity is worked out

Gravity is a depression in space fabric.

Hi MrVat7,   
Thanks for your response, but  I know Gravity is a depression in space. That's the common , non-descript explaination that is quit common. I refer to it in my post as--- 'what all the existing definitions of gravity say'. But that does not come close to explaining what gravity "IS" and how it was created. My theory attempts to describe how gravity was created, and what I think is a better explaination of 'what gravity is' and where the force of gravity comes from.  Perhaps my crude sketches do not make a clear picture of my theory. It is difficult to explain clearly.

I think the curved space comes from the distortion in space caused by space particles joining together to form suns and planets 'pulling in space toward the center of the body being formed. And the force of gravity is caused by an object on the surface of the 'formed body attempting to return to the point in space that is now deep in the middle of the formed body.

 As I said above, this theory is difficult to explain simply, so I guess that's why it is difficult to comprehend.

The main thing to investigate are the vectors needed for objects to miss each other. That is what people don't understand. By the time the gravity wave reaches an object it will direct it to where the source used to be and not to where source is now. If a transverse velocity is not too strong or not too weak for the approaching object it will orbit the source. If it is too strong the trajectory will bend but will ultimately escape the gravitation of the source and continue on it's journey. If it is too weak it will describe a parabolic spiral until it collides with the source. Gravitons do not have to exceed light speed for this to happen.
