1. The moon.
2. The law of gravity.
The moon is a mass that is constantly falling towards earth, but will never reach it due to how quickly the earth moves.

Its been a while since I did this topic, but I believe it was mostly because under communism there was little work for intellectuals, so they were often the ones who left the country. This resulted in a 'brain drain', a lack of knowledgable people. I seem to remember reading about the entire maths department of a university just up and leaving at one point. You could also argue that it was damaging for the image of communism if so many people were trying to leave.
