Planets don't just find 'comfy spaces' to hang out in.
They take up regulating roles at resonant distances within the systems.
Solar systems are like giant transformative matter condensors - all part of the ether's effort to return/condense to its original state, only retarded by the spin (misinterpreted as charge/energy) at the 'atomic' level, and the accumulated orders above this (wrongly interpreted as mass with gravity at sufficient magnitude).
You sound like you've not long found EU theory, and have taken it as some kind of cannon.
EU movement is only peeling back another layer on your onion of understanding. Go beyond their thinking.
