1) entangled particles are collapsed “instantaneously”. But it’s not really instantaneous because those particles can’t reach the initial observer/measurement until the speed of light.
2) Superpositions are collapsed which apparently causes different behavior than if they’re collapsed later. e.g. the double slit experiment, where measuring the electrons before the slit causes the interference pattern to disappear. This and Bell’s theorem are very unintuitive but they don’t necessarily break the speed of light.
What if electrons are shot through a very long double slit, where they may or may not be measured early on but the observers at the end don’t know this? This still doesn’t break the speed of light because once the electrons create the interference pattern which the observers can measure to determine if they are entangled, the electrons are already local to the observers.
Bell’s theorem just shows there is no one “hidden state” in entangled electrons before they are measured. The entanglement seems to create the relation “chargeA = !chargeB” without setting “A” or “B”, but when A is finally resolved, it still takes the speed of light for this information to reach B.
