Didn't really think this question fit the Homework section, so I hope this is alright. I need to have 3 sources "for" and 3 sources "against". The difficulty lies in choosing a subject that when I present the evidence for each side, ppl in class and the prof's eyes don't start to glaze over. Its only 4pgs(double spaced, later to become a 5-6pg paper in which I choose one of the sides) so I won't have the space to take every piece of evidence and break it down into layman terminology. Also it doesn't have to be strictly related to Astronomy, any other branch of physics would be fine with me as well. One more stipulation I guess, I'm a 3rd yr Physics undergrad, so I understand maybe on average 25% of what I read in physical journal articles depending on the subject (my forte being astronomy). Point being, the due date is Mar11th and I'd rather not burden one of my professors by them having to explain 6 journal articles to me line by line. Lol, hope this wasn't too confusing. All ideas welcome! thx in advance.
