Falsifiability is usually defined as "the extent to which a scientific theory can be proven wrong". Does this mean that falsifiability is basically the extent to which a scientific theory is testable?
In the case of charge a global $U(1)$ symmetry leads to the conservation of charge, however upgrading the global symmetry to a local symmetry leads to the electromagnetic potential field $A^\mu$ such that:
$$D_\mu =\partial_\mu - iqA_\mu.$$
Since a global space time symmetry leads to the consevat...
If a neutral meson carrying intrinsic spin equal to 1 decays into a pair of charged pions, how can they possibly conserve angular momentum? Pions have no spin and if they originate from the same point then their relative motion can't generate angular momentum either.
Won't they just go their sepa...
