The unsolved problem of Physics, the fine structure constant
Have you heard about the golden ratio? which is 1.618, which appears in nature everywhere, if you don’t believe please read this.
Now more complex ratio to understand is 1/137, which is called the fine structure constant, this constant may be a random setup during the formation of the universe like other constants, for example, speed of light, Planck constant, etc…
If you are not a physics enthusiast, the below video may be difficult to understand, however worth watching.
