Storage Of The Curvature Of Spacetime

My knowledge of high level physics is sketchy at best but I thought I would write down some of my thoughts about the storage of the curvature of spacetime.

Moving an object takes a certain amount of energy, and the motion energy in a moving body according to standard principles of physics is normally half the mass times the velocity squared. One might assume that a planet therefore needs a lot of energy to move it, but a planet moving under gravity doesn't require any energy to move. Motion under gravity is energy free, because it is not motion in the normal sense of the word but a dimensional deflection. Time as experienced by the planet is partially deflected into space resulting in apparent motion. What is lost in time is directly gained in space.

Objects with mass emit gravity. Gravity emits at the speed of light, so if two planets magically appeared in an empty universe, they would not react until the gravitational energy had the time to move from one to the other. Under quantum mechanics continual energy can also be measured as particles, one fixed lump of energy, and the proposed gravitational quanta is called a graviton.

Gravitons transmit gravitational information that causes matter to move. Massless objects such as light also move under gravity, so space itself is affected by gravity, not the objects being attracted. Space is curved by gravity, space curved into time. A body moving under gravity therefore moves more slowly in time, this is the essence of general relativity.

So gravitons cause space to curve but what is the curvature of space and how can essentially 'nothingness' be 'curved'? If some part of space can be curved into time and another not be then some storage mechanism must be present in space.

However any apparent curvature/distotion of space is only detectable when an object moves through it. Space with nothing inside reacts in the same way whether curved or not so the curvature is represented only by the motion of particles in a particular segment of space. Space without particles that can be affected by gravity is entirely flat.

The information of the curvature of a particular segment of space is created (and represented) by a reaction between particles in that segment of space. The reaction between a graviton and another particle would therefore deflect the non-graviton in time and space. It should not sound unusual that a deflection affects the time of the colliding bodies because all deflection reactions affect time and space. When any two bodies collide a particle is deflected from one path through four dimensions along another.

What is unusual here is that the direction the graviton is moving is vital but its location is unimportant. The location of a graviton never matters. Provided a particle can be reacted upon by a graviton, the particle will be deflected towards the place the graviton is moving from and always deflected by the same degree.

A graviton moves at the speed of light so it does not move though time. Its location is never important, so it can be assumed that is behaves as though it appears along the complete length of its trajectory at the same time, so must always move at the speed of light. Importantly this means it is not deflected through time itself even if the particles it reacts with are.

If a graviton has infinite length and deflects particles it could be visualised as a mirror. In a two dimensional plane a mirror has one dimension, and in a three dimensional world a mirror has two dimensions. A graviton has no time so it acts like a three dimensional mirror, deflecting particles through four dimensions.
