Hundreds of millions of years ago, it was getting larger by a hairs breadth. That increase is not enough to give rise to gravity so that is why the bulk of the expansion has to be into hyperspace. You need more expanding size and speed to match what we see as gravity. All that means is that the satelites that are measuring the size of the earth and the earea between the earth and them, have to be expanding in unison. So why this 22 mm then? Momentum. A kind of momentum, a kinetic energy. You know there is dust in space, but how much dust is sitting on the mares? That is like the question people ask if comets brought water to earth, why didn't they briong it to the other rocky planets? Special delivery? Because of the mass of Jupiter and the Venus was too warm, Mars is too um void of water to agree with that hypothesis. There are lots of things we still pretend we don't know.

Momentum. >A kind of momentum, a kinetic energy. > Are we destined to become a gas giant? (Silly questions are still good questions) How far away is the moon moving away fro us every year? 3,8 centimeters. I dropped my slide rule. Is the distance away from the earth proportional to the increase in earth's diamter of 22 mm? Lets assume it is, and both the quantum foam betyween us, and the earth itself are expanding along with the universe, only the 3D expansion part described here is just a secondary effect, a residual momentum outward caused by the expansion of space-time. Newton and Descartes thought like many physicists have that particles were streaming outward through all atoms from their center. And that friction was causing gravity. Thats not a bad description if you believe in particles. But where is the elasticity? That elasticity that Einstein saw and described in Brownian motion? It works better when we consider that the fabric is elastic. in some way. Somehow elastic yet stretching so fast so much that according to some estimates if you were to go on what you see in terms of galaxcies moving away, that it is expanding at the speed of light. Well that has to be an optical illusion. Acellerating as it expands. Expanding faster. That is easy if it is expanding according to the inverse square law. That is accelleration. If it is doubling in size. That is what works. Doubling in size in unison with a residual momentum that can be measured. The king of Sweden has a blue ribbon put aside for someone who can figure this stuff all out.

Consequently, its decimal representation never ends or repeats http://mathworld.wolfram.com/Pi.html http://en.wikipedia.org/wiki/Pi "π (sometimes written pi) is a mathematical constant whose value is the ratio of any circle's circumference to its diameter in Euclidean space; this is the same value as the ratio of a circle's area to the square of its radius. It is approximately equal to 3.141593 in the usual decimal notation. Many formulae from mathematics, science, and engineering involve π, which is one of the most important mathematical and physical constants. Unlike many physical constants, pi is a dimensionless quantity, meaning that it is simply a number without physical units". "π is an irrational number, which means that its value cannot be expressed exactly as a fraction m/n, where m and n are integers. Consequently, its decimal representation never ends or repeats. It is also a transcendental number, which implies, among other things, that no finite sequence of algebraic operations on integers (powers, roots, sums, etc.) can be equal to its value; proving this was a late achievement in mathematical history and a significant result of 19th century German mathematics. Throughout the history of mathematics, there has been much effort to determine π more accurately and to understand its nature; fascination with the number has even carried over into non-mathematical culture".

What happens when you get to Plank length? Planck length is physics. Pi is mathematics. Learn the difference.
