Big Crunch or Big Rip?

Believing in absolute determinism and absolute certainty allowed Einstein to say that quantum accounting "produces a good deal but hardly brings us closer to the secret of the Old One. I am at all events convinced that He does not play dice".

But quantum dynamics is a game of dice going by the uncertainty at that level.

But quantum dynamics is a game of dice

But not the regular six-sided die. It is more like an infinite sided die or infinite degrees of freedom. But in a theory of quantized spacetime only 8 degrees of freedom (8 directional invariance properties) can sufficiently able to describe a 3D object.

I thought in the quantum world you had only two options at any time. Much like the logic gates in Electronics. I thus stand corrected.

This is true for the intrinsic spin and the electric charge polarity.

Magnetism also which is derived from electricity.

That is not completely correct according to the classical Maxwell's equations.

[dipayankar]

Electricity and magnetism are interdependant. In fact in some ToE I saw that they are the same thing.

That is not completely correct according to the classical Maxwell's equations.

The mysteries of classical electromagnetism is the fact that the divergence of the magnetic field is zero and the existence or non-existence of the displacement current. However, if the magnetic field is the curl of the magnetic vector potential then the existence of this magnetic vector potential and its gauge invariance can answer many questions of quantum field theory.
