Well - according to mainstream theory the planets have basically been in the same places since they formed. Except for a few minor adjustments due to
some wandering bodies - the theory regarding a planet called Vulcan for example, which was theorized to have wandered around then fell into the
Personally, however I don't subscribe to mainstream theory.
There is an alternative theory that I like, that says the planets sit on 'nodes' of oscillation in the vacuum. The nodes are caused by a waveform
that ripples out from the sun causing low 'density' in the vacuum.
The vacuum itself, according to this theory, is not empty - but rather is an extremely dense, pressurized fluid. Inside every planet then is an area
of very low density, being a black hole.
So these won't really move much over time, and are locked into their particular orbits by the movement and ripples in the vacuum.
Also according to this theory, the black holes inside the planets keep creating matter, which powers the internal mechanics of those worlds - causing
them to slowly expand over time, causing volcanoes and earthquakes - creating water, rock, oil and gas.
FOr a quick into, have a look at a youtube series called .. hmm .. the growing earth theory - or expanding earth theory. That video set covers the
practical details and explanations behind why the theory predicts an earth that is increasing in size.
As for the fluid vacuum theory - hmm - have a look around, I can't remember any specific sites - but it is detailed and expressed by more than one
theoretical physicist. But it not mainstream
Because it conflicts with Einsteins theory of relativity.
However there was a famous set of experiments doen to detect 'ether drag' by a guy called Dayton Miller - who DID detect ether drag, but at much
lower velocities than was expected - his results were swept under the carpet by the Einstein personality cult following. In my view this was a
disaster for science - and I feel it was done by the NWO in power at that time.
That is also why Einstein has become such a personality cult - they are trying to ensure that anyone who challenges relativity - and certainly anyone
who might assert that the vacuum is a fluid, and not empty are seen as scientific pariah.
Anyways - happy thinking
