What's inevitable (like a compass pointing north, water finding the ocean, or the sun rising & setting)? thx!

I am writing something for someone I love, and I need to refer to things that are constant and consistent. I have listed some examples in the question, but am searching for more. Any help you could provide will really help me impress her!
