Folks , I have a hypothesis that even stars like our Sun have their own inner Sun ! I say this because stars also have Auroras like planets do . So if Hollow planets get their Aurora from their inner Sun , then maybe Hollow stars too get their Aurora due to their inner Sun ??
**To my mind , stars and planets are at different points on an energy spectrum - above a certain threshold you get hollow stars where even the super heated outer "shell" becomes plasma , if it is just below that energy threshold , you get failed stars or gas giants , where the outer "shell" is made of gas . Then we come to smaller ones , or planetoids that are well below that critical energy threshold and in which the outer shell solidifies , but they can sustain their inner Sun eg. rocky worlds such as Mercury , Venus , Earth and Mars . Finally , there maybe a smallest category , which is so far below the energy threshold that , the outer shell solidifies and even an inner Sun cannot sustain itself - these are moons.
While stars , planets & planetoids display Auroras of varying intensity , moons usually have no Aurora.
***Fundamentally , the same laws of physics must apply to all celestial objects and only a difference in their energy levels determines whether they become a star , planet , planetoid or moon...!
Guess what , this again points to the fact that Auroras are intrinsic properties of celestial bodies AND that they emerge from some orifice at the surface that leads into the (hollow) interior - be they planets or stars , there is no "EXTERNAL" driver to their Auroras - like the Solar winds that "allegedly" cause Earth's Auroras :))
What do you think about all this ? Hmm...!
