We have kind of a class debate tomorrow. There are two teams, one tasked to provide evidence supporting the protoplanetary hypothesis while our team was given the job of countering the said evidence.
As far as I know, the protoplanetary hypothesis is, at present, the most widely accepted theory on the creation of our solar system. That, combined with the lack of substantial information about the topic online, makes our job incredible difficult.
What parts of it lack concrete evidence to support the concept? If there is an explanation, what it is a highly debatable one?
Thank you!
