A:

First, I should say that it doesn't mean anything to say whether or not something is "moving" unless you say moving with respect to what other object. Still, your teacher is right that different states of motion have different effects on the universe. The reason is that all objects have long-range fields (gravity + maybe some others) that propagate even through a vacuum and thus affect other things.
