I am a writer for a newly forged independent film studio. We've managed to drum up some (surprisingly) considerable funding and support from our local community, and along with that we have been allowed access to an observatory and astrophysics department on a nearby college campus. We've managed to come up with a story concept and characterizations, though as a blustery English major, I find myself lacking in the technical knowledge in order to pull off the story gracefully. What I am hoping to get from the community is this: I need to be referred to an event involving a hypothetical observation of celestial bodies that would potentially forever change the way astronomers and astrophysicists think about the universe. Basically, I want to know what the unicorn everyone is chasing might be. Think Higgs Boson for the stars. I don't want to write something cheap and uninformed, and I hate it when even a simple hobbyist like myself can see gaping holes in the scientific explanations of otherwise realistic filmmaking. Please help me represent the scientific community in an interesting, engaging, and accurate manner. Thank you. I look forward to any and all responses.
