Leading Theory of Solar System's Formation Just Disproven (forbes.com)
StartsWithABang writes: In 2005, scientists put forth the Nice Model to explain the configuration of the Solar System's planets. It was thought that the outer planets, Jupiter in particular, migrated through the inner Solar System, and were then pulled back out by the presence of the outer giants, causing the late heavy bombardment of the terrestrial planets as it crossed the asteroid belt. But not only are extra gas giants that have since been ejected required to explain the outer worlds, but the migration would have ejected the inner, terrestrial worlds, indicating that the rocky planets finished forming after the gas giants were already in place. R.I.P., Nice Model: 2005-2015.
"So a model gets discarded because it won't work. Nothing to see here."
Fortunately, this model is in a discipline which has not gone political. We can make changes to it without holding any Maoist show trials where researchers get called "deniers."
I don't know about that. The status of Pluto seems/ed to be pretty political.
The five senses we humans possess are those which allowed us to adapt to our environment and live in it; there is no reason for me to believe they are sufficient to explain our universe.
That is, if we are smart enough in the first place, which is very, very doubtful.
I would add to Socrates' famous quotation, "All I know is I know nothing," the phrase, "and I can't even be sure of that."
