Another Entanglement theory question

What happens if you have 2 particles entangled, and they are both observed simultaneously? As I understand the randomness in QM, once one particle is observed, we only know certain information about the other particle, redundant information. But entangled particles being observed simultaneously, this seems like it may have strange implications.

Thoughts? Or will this have a simple explanation?
 
I don't know what "strange implications" you are expecting. First of all, the "simultaneity" of the observation cannot even be confirmed due to special relativity. Then if they are observed within a similar time frame, what are you expecting? Observing them would merely collapse the wave function and observing the other would merely confirm what the first reaveled.

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
