Sciartist

Hello! I'm Rami... Nice to join ya. I am very new to science forums, I understand forum etiquette so I wanted to ask where I should post my topic. I am Writing a screenplay which involves a futuristic world that involves force fields, time, Astroids/Meteors, and drastic climate changes. The reason I am on science forums, is because I'd like to have my information as accurate as possible anyone have an idea what thread(s) should I ask my questions/topic?
