Questions of the day: correlated particles

1. If one correlated particle goes into a black hole or otherwise changes state in a way that only happens with those specific surroundings, and the other one therefore has the same state, would this also change the surroundings of the second particle in order to make sense of that state? So like would it actually make a black hole?

2. I one correlated particle was in another universe very similar to ours, and in one universe they charge the particle, would the other universe’s scientists be able to detect this and would it be a way for us to communicate with them?*

*assuming the many worlds theory is right

If you can answer these questions for me, please leave a comment with your thoughts 🙂
