Alright, but if they evolve separately, do they just not evolve fast enough for us to not know if the spin has changed since the entanglement stopped?

So once a wave function has collapsed by the observation of A, B is permanently the opposite from then on? So is this ultimately saying: everything is random until we measure it, then it is a certainty; that there is no way to know anything before?

Thank you for the response, this was really helpful! A question I have then is what if you measure them at the exact same time?

I will have to look into those videos. I guess what my question boils down to is: How do we know that these particles just aren't in complementary states from the start? It seems like we are saying that there is some connection between two entangled particles when in reality they were the same...

Further on how these experiments have been carried out, are the particles constantly changing after the entanglement or are they a solid state? If they are solid state, have we tried making stuff entangled, measuring it, changing one, measuring the originally changed one, and then measuring the...

Thanks for your reply! So I understand that there are no hidden variables, but could you help me understand what the experiment that has been done is? As I understand it, if two particles become entangled and they are measured, then they will be the opposite of each other; in this case, what is...

It seems to me that so far in quantum mechanics, because we have yet to establish probability patterns for, say, what the spin of a photon is, we have made it some mystical thing that we can only know by measuring it. I don't really buy that; is the result of a lottery impossible to know until...
