**moving gravity fields**

Whether a star's gravity field happened to be fixed in the centre of the universe or elsewhere, the earth could not be experiencing a suspended motion in a fixed gravity field.

Apart from mistakenly employing an equivalence between acceleration and uniform motion, Galileo's explanation of planetary motion was unable to fit with any of Johannes Kepler's laws of planetary motion.

## Kepler's Third Law

A century or so after the life and times of Nicholas Copernicus, Johannes Kepler meticulously developed three laws of planetary motion. One of these laws, the third, was saying nothing but the existence of a causal link between the magnitude of the sun's inverse square law at a planet's distance from the sun and the average speed of a planet relative to the sun. That link can not be investigated through the motionless gravity field physics of Sir Isaac Newton.

The classroom solution to Galileo's misapprehension and planetary motion itself is all descents are relative speed changes following

**curved**paths. The superior speed of an inverse square law relative to the accelerations caused within an inverse square law by an inverse square law is the key to orbital motion.

Or, if Sir Isaac Newton had of observed his descending apple as an acceleration relative to the motion of the planet he was on, his fixed earth sleight of hand cannonball physics would not currently be part of a junior school physics teacher's classroom spiel.

This relatively slow moving curved motion can become an orbit if the descent falls through either of........

a/ The path of an inverse square law.

b/ An axis at a right angle to the path of the inverse square law.

That's Johannes Kepler. According to modern astronomers and relative to the centre of the galaxy, the sun travels approximately 10 times the earth - sun separation in a 1/4 year period. At the sun's distance from the centre of the galaxy, the path of the sun's inverse square law during an earth year is indifferent to that of a straight line.

In rudimentary form, the real solution to planetary motion begins on the following animations. On the first one, the elongated inverting blue curves in total are an introductory glimpse of what a year of the earth's galactic journey looks like. The thing for physicists to note is, using this chosen start of the earth year point, for the first six months of the year the acceleration within the advancing blue curve is in the

**opposite**direction to the advancement. Meaning the earth decelerates for six months. Then accelerates for next six months and so on around the galaxy.

*[In three dimension the angle of the planets to the path of the sun is currently reckoned to be about 60 degrees. Not the zero degrees as appears on this two dimensional animation. Thus the 60 km/sec absolute speed differential over a six month period will be less.]*

The growing red arc is all that the Copernican revolution sees at the moment.

The elongated inverting blue curves is where a scholastic reckoning of the nuances of galactic planetary motion commences.

The fact of a biannual earth speed differential within the motion of the sun's inverse square law is

Through Kepler's third law we can work out that every increment of daily advancement of the earth is the equivalent of a straight line speed change rate of about 0.0000059 metres/sec/sec. In contrast something dropped at the earth's surface has a much greater speed change rate of 9.8 m/s/s along its curved path. Using a larger distance and one larger time parameter, the earth's constant speed change along its curved path is about 0.512 km/sec/day.

The hidden rocket science is an ongoing inverting curving speed change becomes a cyclical zero speed change if the inversions become the completion of a 'circle' around a central point like that of a 'uniformly' moving star.

Extra resources are required for greater and also three dimensional accuracy. This does not compromise the fact that the reason the planets are not spiraling into the sun is the motion of the sun's inverse square law. Not Galileo's four hundred year old ascending perseverance mistake in a fixed sun's gravity field.

Someone else has a less to the point (the planets should be in front of the sun half the time) but more cinematic moving sun animation on YouTube.

The indispensable knowledge is the earth's apparent direction of fall towards the sun orbits the sun. In a pendulous rhythm, the earth itself swings across the speed of the sun. Physics teachers and their classes are on

**a galactic journey**, not a Copernican fixed sun journey, etc.

From the space venture point of view, N.A.S.A. already has moving inverse square law physics in use.

The gravity assist technique used by a passing spacecraft to gain relative velocity is actually at the heart of where planetary motion tutelage should be. The technique would not work if the inverse square law of Jupiter, for example, was considered to be fixed in space in the way Galileo and Sir Isaac Newton considered the sun's inverse square law to be fixed in space.

To reiterate, what Galileo did 400 years ago was confuse the path of the sun's inverse square law with the irrelevant consideration of where the earth would go to if the sun did not have an inverse square law.

The critical post Copernican conundrum that arises is the one of how and why the moon accelerates and decelerates in accordance with both the sun and earth inverse square laws.

The sun - earth - moon relative motions is the riddle in search of solution.

This statement was made by Sir Isaac in a fixed sun age. The man's ignorance about the motion of a 'gravity' field means he was not an appropriate or true calculator of the motions' of heavenly bodies.

The overriding point about Sir Isaac's calculations being the Copernican revolution wasn't really a revolution. It was a correction from a fixed earth error to a fixed sun error.

Einstein's similar styled sentiment was not condescending to the whole world. For someone taking charge of the inverse square law, Sir Isaac's attitude to other people was unfortunately governed by personal insularity. Not that it was unusual for the times, he had investments in the slave trade and could not easily be considered a humanitarian.

Something else is, using the sinusoidal nature of a planetary year, there is the possibility of calculating the absolute speed of the sun. In conjunction with astronomers, mathematicians of repute could be giving their black holes a rest. At this stage there are a lot of challenging unknowns to the task.

Ignoring the ellipse and the angle of the path of the sun to the 'orbits' of the planets around the sun, the angle (phi) between the path of a planet and the path of the sun is..

Where a planet cuts across the path of the sun is where a consideration of the calculation of the speed of the sun can be done.

Allowing things to be two dimensional and a constant distance from and speed relative to the sun, while the sun travels from where it was when a planet cuts across its path to the cut across point, the planet advances around the sun through the angle phi.

Problems outlined overcome, calculating the speed of the sun is still a sizable task for mathematical physicists and astronomers to undertake. Separate equations involving V and phi is the starting point. Getting on top of day lengths is the more important chore at hand.
