Not understanding scientific principals does not mean one is lying, only that he is perhaps unqualified to describe (scientifically) what he seeks to describe. I can personally attest to this. There is a lot I wish to describe but do not understand enough of physics to do so scientifically. Thus I make the effort to learn the science. But that is a personal choice I’ve made. No one is obliged to learn physics in order to describe something. Nor should they be chided for it – unless they in fact attempt to present themselves as so qualified.<br /><br />To say that EarthSister is lying is as patently unscientific as anything she may attempt to describe. If she is wrong, the facts will bear that out in time. But even then this is not proof that she is lying (as in, to deliberately deceive). She may very well believe something that is not true. If that is the case, then it means she is wrong, not that she is lying.<br /><br />As for a planet leaving its solar orbit, I am quite sure that even changing its center of gravity would not do this by itself. In fact, as I understand the dynamics of orbital velocity, even changing its mass would not change its orbit, but would only effect the orbit of something that orbited it. It would necessarily take the application of an enormous amount of energy (probably from an external source) to change a planet’s orbit. Thus if the tiny planet’s orbit changed, some force was applied to it.<br /><br />What would that force be? How much energy would be necessary to achieve this? Of course, that planet’s original mass would have to be known in order to know how much energy would be needed.<br /><br />Here I will pose a question. Let’s suppose this mystery planet were incredibly active, seismically, more so even than Io. Is it possible that a super-massive volcanic eruption could occur that threw enough material off of said planet to change its orbit this significantly? <br />
