Nice Model of planet formation is probably wrong

Models are showing that the Nice Model, where gas giants form first and migrate into the inner system and then back out, would have less than a 1% chance of NOT disrupting or ejecting any smaller inner system bodies. So it's probably wrong.

What this means is that, if correct, we can no longer explain close gas giants. *sigh*

Does this model include the gravitational perturbation due to the formation of WP's ?

(note : I didn't write "pertubation due to WP's" , I wrote "perturbation due to the formation of WP's ,
unless of course the actual process of WP formation has already been explained.......)

*laugh*

Perhaps we should be looking for an unexplained clump of asteroids in the belt?

It would be nice if WP were the missing dark matter/dark energy.

Well until something hostile shows up. IND planets never do well when visitors come.

Actually, given the number of intergalactic stars found in the Virgo Cluster, it's possible that a significant amount of mass is in individual intergalactic stars too faint to make out with current telescopes.

Interesting thought... whether this is possible depends upon how you define WP, of course.
