The first rule of world-building is available physics, which basically means that if you want it to feel real, it has to follow the same rules as this world, from gravity to how human behaviour works. If you have a fantasy element that doesnt obey the laws of physics, make sure that it has a fantasy explanation.

You would have to ask a physicist really but I think understanding fundamental problems in physics is very important because they are part of our culture. You just never know what is going to come from it. If you had told Isaac Newton about spaceships and satellites that arise from his laws of gravity, it would have been science fiction to him.
Venkatraman Ramakrishnan
The idea that God is an oversized white male with a flowing beard who sits in the sky and tallies the fall of every sparrow is ludicrous. But if by God one means the set of physical laws that govern the universe, then clearly there is such a God. This God is emotionally unsatisfying... it does not make much sense to pray to the law of gravity.
Carl Sagan
Increasingly in recent times we have come first to identify the remedy that is most agreeable, most convenient, most in accord with major pecuniary or political interest, the one that reflects our available faculty for action then we move from the remedy so available or desired back to a cause to which that remedy is relevant.
