“The icy worlds beyond Neptune trace how the giant planets formed and then moved out from the sun,” discovery team member Michele Bannister, of the University of Victoria in British Columbia, said in a statement. “They let us piece together the history of our solar system.”
Bunch of hogwash. Their whole planetary nebula model of solar system evolution has been up-ended by all the observations of exoplanets, and finding more dwarf planets beyond the gas giants in our own solar system certainly does nothing to help them salvage their model. Until they acknowledge the situation and come up with a new model, they’re just putting band-aids on a gaping wound.
It's all in their heads, so therefor, no actual wound?
Like honeybadger, exoplanets and dwarf planets don't care.
But -- why doesn't the concept of exoplanets, dwarves and other debris drifting out beyond orbits of gas giants (eventually out of range of being vacuumed, swept up by gravity of the big planets) not work as a postulate?
