The best part about the fine structure constant is that it is not related to any other thing. It just is.

It's a magic number that just emerges in physics.

And it is not constant.

Even though it is.

Dimensionless numbers, not dependent on any mere mortal, subjective arbitrary unit of measurement like length (meters or yards or cubits - same difference) or time.
Whether you are on Earth or a planet in Andromeda or a billion light-years away, if you study subatomic structure you WILL bump into the fraction 1/137. Just like you will in geometry with 3.1416.
