Is the total spin of the universe zero?

[Antonio Lao]

Is the total spin of the universe zero? Clockwise? Counterclockwise?

Is the spin symmetry broken for elementary particles?

The total angualr momentum should be zero, strange things satrt to happen when it's not. Spin does seem to be a universally conserved quantity.

 

[Antonio Lao]

The total angualr momentum should be zero

But what about the components of angular momentum? Are there only two quantized states of the angular momentum? Clockwise and anticlockwise? But the magnetic dipole moment indicates otherwise. This moment cannot be canceled out. There seems to be only one spin direction for the magnetic dipole moment.
