3 Calculating the Past
By Tom Brown
The Moon is very slowly receding from Earth it is predicted even by elementary physics and can be measured. This is a simple fact and is the result of losing energy. We might then work out in reverse and theoretically to the very start where they were together.
Orbits and Time
All the rotations slow down as the Moon slowly moves further away due to gradual but steady dissipation and loss of kinetic energy, in mutual orbit revolving around the system center of mass. The orbital radius increases with time as the bodies move further apart. It is well known that the energy dissipation is due to drag of the sea tides.
Reconstruction of the history of formation and subsequent development of the system is in principle possible.
The idea is after this break-up, or not, modeling the regression is in fact "back-tracking" as it were. The revolution rates, the Moon day and Earth's and the orbits might be calculated back into history (but in practice only roughly really) hopefully right to the moment that is where the Moon became a distinct entity.
A very strange thing and it is very well known, the Moon's same side always faces the Earth and never the other the far, the blind side, it remains always hidden. Swinging against gravity like a pail of water or a hammer to be thrown. This fact is what my theory is built around.
Visualise the following, the orbit was in step thus and might have been throughout its evolution with time, so that the Moon orbit was synchronised in this way from the start. And then if right through time and ages it was the same, and has always been so, facing Earth whilst at the same time steadily away all the further.
Thus I believed there will exist enough related evidence of a very convincing fission theory and really it all sounds very reasonable.
There are more instances of this kind of what is incredibly unusual type of behaviour in our solar system alone, such as of with Jupiter's moons and the planet Mercury.
Can it possibly all be coincidence?
Originally one body?
There is by now not much doubt that the Moon and the Earth-Moon system indeed started as a single body probably beginning with a breaking and separating into two distinct entities. In agreement the chemical composition of the Moon and the Earth's mantle is very similar and other facts argue too for instance that there is water on the moon.
This all sounds very convincing for a simultaneous origin of both to be the one very massive rapidly spinning object. But then how the actual "break-up" happened your guess is just as good as anyone's.
I reasoned that if this proto-earth was spinning fast enough in the super-heated fluid form maybe there could have occurred such a spontaneous splitting in two, thinking too of the nature of the bond and gravity as compared to other fields being an extremely weak type of force. At this point it is all speculation.
Newton might well have done exactly the same he had all he needed, George Darwin (son of the famous 19th century biologist Charles Darwin) was the first to propose a serious scientific explanation as a fission theory, however it was objected that angular momentum at present is much too large for an original spinning body in which at the start at this break-up would have to be prohibitively large.
Of course the angular momentum of an isolated system stays the same through time it is constant and always was equal and will always be according to conservation laws.
It is not to say the fission theory has been disproved, reality is a great deal more subtle you have at the least influence of the whole solar system including Sun and planets things are not so clear. Any acceptable description of the whole over time is hopeless because of unbelievable complication. For a start the mere geometry defies meaningful study.
Even the tiniest perturbations over very long time periods distort kinematics drastically resulting in unbalanced and unpredictable behaviour. It is also incredibly hard to work accurately with eccentric orbits and rotations, all leading to hopelessly impossible complexity.
Calculations of long term distant future prediction as well as history of extremely remote past has intrinsically to be highly inaccurate. This is inherent and unavoidable as shown in chaos theory. Errors and deviations compound first very slowly then faster and the faster and exponentially.
Of course there always are many things you don't know about and thus cannot take in consideration however it is time to seriously revisit these ideas.
A proposed simple model
The proposed simple model is an approximation of very typical real physical situations. This is essentially an engineering problem. I also need to emphasise that the Moon-Earth system is only one possible application and in fact there are others where this analysis should be even more successful.
The analysis will be provided in blogs but I am not so confident since mine comes out rather smudged and unattractive. My actual calculations will hopefully be in the last submission on the Earth-Moon and with sketches.
Each of the current theories has glaring shortcomings and that includes the one proposed here as yet there are no acceptable explanations. Where our heavenly companion came from is an open question even today and remains a haunting mystery.
