Also, DW's research is focused on an outside energy source for an explanation of the planets heating up, and not of a planet moving into close proximity to the Sun.
Except I thought Pluto was moving away from the sun out into whatever energy is coming in from the outside?
[edit] here is one site where I got that idea
