Problem of Double Cover

It shows up in Physics a few times: (1) g-factor =2 but being explained using SR as Thomas Precession but half of expalined by CP, (2) Deflection of near Star's light by Sun by factor of 2 explained by GR but half of what NG explained, and (3) Left Handed Parity of Beta Radiation.

In nature and in Universe, it can be seen that something of a Spinor or Complex Vector rotates twice faster than the particle. The equation of SHM in Geometric Algebra would confirm this aspect.

So what (3) shows that there is a speed of light or at the speed of Quantum Entanglement the observed Universe is "spinning" twice faster - or it is acting like a spin particle of 1, which means besides the Visible Universe accelerating it is also being pointed in one direction!

Is it not obvious when one thinks of the Visible Universe coming from Big Bang? This geometriy of Visible Universe is conical but our view of the universe is spherical.

Other way to think of, the angle of subtended at the center is twice of the angle subtended on the arc.
