**Copernicus's mistake**

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

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 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, planetary motion education today would plausibly be hunky dory.

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 curves in total are an introductory glimpse of what a year of the earth's galactic journey looks like. The thing for a physicist to note is, using this chosen start of the earth year point, for the first six months of the year the earth's galactic direction is

**opposite**to the earth's Copernican direction. (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 speed differential over a six month period will be less.)

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 0.512 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.

Relative to the impossibility of fixed sun planetary motion, these animations are starting points for school teachers to get underway with. In keeping with the discovery of the superior motion of the sun, the overdue task is getting rid of fixed sun planetary motion tutelage.

The indispensable knowledge is it's not the earth that is orbiting the sun, it's the earth's apparent direction of fall that orbits the sun. School teachers and their classes are on a galactic journey, not a fixed sun journey, etc.

**Full Orbital Suspension**

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.
