Engineering Problem?

Okay, if there is an engineering problem. There is no gravity in space, but i will guess that the journalist would mean galaxy. It is all gravitational with lens that produces the image. It will be not true, but sounds like probably mean galaxy. What people would think might be true or not true. I do not mean that kind of galaxy. If there was any gravity in space, all the planets would break the chain, and all fall down like pinballs.
