What is science if not taking a theory and trying to either prove or disprove it? What are your thoughts? Question of the night. For those of you who automatically say that it is not a Science why not consider the fact that NO ONE knows EVERYTHING and open your minds a bit and think before answering. Argue the point with yourself before jotting anything down. The reason I say this is earlier I read a response that someone made that was short and convinced on a subject that is really difficult to be convinced in unless you are driving to be convinced by witnessing repeated paranormal activity. So...what do you say?

As a kid, when I learned that the earth moves all the time, I used to hop to find out whether I would land at a different spot. The experiment failed every time, and humanity lost another Galileo. The question is: how high should one jump to land on a different spot, and thereby prove that the earth revolves?

When photons pass by a large mass, say a planet, does the planets' gravitational field act on the particles of light and accelerate them to a higher speed much the same way we get the "slingshot effect" with spacecraft?
