Why is this paid??
there's some excellent science simulation going on in here. when I'm teaching middle school kids about our solar system, I get to let them come up with absolutely bonkers experiment ideas and see details like, will changing the orbit that way make the planet freeze, what happens to the atmosphere if we stop the earth's spin, how many jupiters do we have to smash together to make a black hole ... the list is nearly endless. this is worth some bucks, folks.
