the orbit theory (implications)

The orbit theory looks at the universe for the grounds of it's theory.The universe has been expanding for many years now.It is impossible to tell whether it is expanding at an increasing or decreasing rate.It will expand outwards away from the centre at first at an increasing rate and then at a decreasing rate as the amount of energy stored up will gradually dissipate.The expansion has been caused by the energy of all the galaxies being compressed into a small space and gradually expanding outwards like cellophane rolled into a ball.But there is a limit to the expansion as there is to the cellophane expanding.There is a finite amount of material in both balls.
Slowing down
It is possible that the difference between the speed of the earth and the sun (travelling outwards from the centre) will soon reduce;if it has not already done so.If the earth was going to move out of it's orbit instead of just bending  it's shape then it would likely have done so already.It can almost be guaranteed that the rate of expansion of the universe has been greater in the past

 than it is today.It is the velocity of the earth travelling outward that might take it out of it's present orbit.However if it has broken out of it's orbit envelope the warming of the earth would have been greater than it's present rate of increase which is roughly 3 to 4 degrees over the last century.After all,the difference in the phases of the orbit around the sun can make the difference between summer and winter or 80 to 100 degrees.So in conclusion the earth's orbit may be bent or misshaped but still in the same orbit.
