The Effect of Dark Matter on Space flight
The problem with Dark Matter is it is everywhere that visible matter is – just like Dark Energy. But some scientists think that it is also inexplicably where it shouldn't be namely the outer reaches of galaxies.
So it seems not to be uniformly distributed. But I have shown that there is another way to explain this by providing matter with another fundamantal property that of self propulsion.
For every unit of visible matter in a galaxy or solar system, there is 5.7x as much Dark Matter. Between the Earth and Sun there should be 5.4 x as much Dark Matter as visible matter including the matter comprising the Sun. Is this ridiculous? You may well say that the Dark Matter is distributed very thinly between the Sun and the next solar system so the gravitational effect will be thinly distributed and therefore insignificant. O.K.
Where is 5 x more matter in our solar system that we can't see? Not only is it invisible, but its volume is amorphous. It is called matter yet it has no defined volume and we can sail through it without colliding with it even though it has 5 x more mass and gravity than the visible matter in our solar system. We are also told that billions of dark Matter 'particles' are bombarding every square cm of our planet every second so they must be very fast moving. Anyway I could ask why they are fast moving? They could just as well be completely stationery or floating about in a leisurely fashion, slowly acreting particles of dust for the deveopment of the next solar system. Has anybody thought of this before now: Why is Dark Matter, having such a huge gravitational advantage over ordinary matter yet quite definitely gravitationally able to attract 'our' Baryonic matter to it, not causing visible matter to clump to it. Perhaps it has to go so fast to keep out of 'our' way as it doesn't want to clump to us. This raises another question: Is Dark Matter gravity different from baryonic matter gravity? Perhaps one should not ask too many questions. The answers make uncomfortable reading.
And then there is the search for Dark Matter, the dark particle or dark object. The Dark Matter particle remains invisible to the cleverest and most sensitive instruments. There are not enough dark objects to even begin to account for the amount of mass. A chunk of Dark Matter is thought to be baryonic matter and the rest … well … ehr... it is gravitational matter because it causes gravitational lensing. Fundamental properties of matter are gravity and volume and mass so it must all be baryonic matter or is there …ehr … some other exotic form of matter that has mass, exerts gravity but has no volume (like the will o' the wisp. It is here it is there it is everywhere) and as it has no defined volume it is invisible and if it has no volume how can it exist? Perhaps you should call it gravitational Dark Energy (except energy isn't supposed to be able to be gravitational although electro-magnetism is). Perhaps the reason that Dark Matter particles have not been detected is that they don't move very fast like Cosmic Rays. You can't presume that Dark Matter particles are fast moving. As I said, they could be just floating about in a leisurely fashion not bothered if anybody finds them or not.
So before looking at the relative movements of the planets, I want to have a quick look at how space science deals with Dark Matter in our immediate facinity. By space science I mean the science of launching and navigating human space vehicles through Dark Matter.
I am raising this because I was pulled up by somebody a while ago when he challenged me with the question? "If you are right about matter being self propelled then how is it that space navigators manage very well to compute trajectories without having to worry about planets propelling themselves or for that matter the satelites propelling themselves?"
Whether we like it or not, 'Dark Matter' pervades our solar system and its gravitational effect has always been there and somehow, space scientists have managed to cope with it. Either the effect on ours satelite navigation is insignificant or they have long since learned to correct for it or make adjustments for it during a space flight. The fact is that they can accurately compute the trajectories of planets and their satelites with or without 'Dark Matter'. And they can accurately plot trajectories to the required destination not withstanding Dark Matter or the fact that matter is self propelled.
So changing the name of Dark Matter to self propulsion of matter does not change the gravitational profile of our solar system or the objects in it and space scientists can heave a sigh of relief.
