Induced electric field and electric field due to charges obey superposition?

Say a group of charges and a varying magnetic field exists in some region. We'll have two electric fields,due to the charges and due to the magnetic induction. Does the...

Is temporal causality broken by quantum entanglement?

When one particle of an entangled pair is measured, it forces the state of the other particle. This effect propagates faster than we can measure, certainly faster than light and...
