In the Schrodinger equation if you rotate a 1/2 spin particle by 360 degrees it looks and behaves differently. You might think that shows that the Schrodinger equation doesn’t describe what happens in reality, after all if you turn around by 360 degrees you end up looking exactly the same to others and you’re looking in the same direction, but that’s not the way the weird quantum world works. If you tip the axis of a spin 1/2 particle like an electron by 360 degrees with a magnetic field you can tell that something has happened to it because it behaves differently, you need to rotate it twice (720 degrees) if you want the electron to be in its original state. For a spin 2 particle like the Graviton (if it actually exists) a rotation of 180 degrees would result in the particle looking in the same direction as before the rotation.
