If you entangle two particles at the quantum level and then take particle 1 on a trip around the world. Due to particle 1 traveling closer to the speed of light that particle two it has traveled through time slower than particle 2. Now if the state of particle 2 is changed will that be reflected in particle 1 instantly or after a fraction of a millisecond. If a time difference is encountered what would happen if you change the state of particle 1 would particle 2 already have been change a fraction before or not ?

That's not how entanglement works. Operations on particle 2 are not reflected in particle 1 -- not instantaneously, not at the speed of light, nor at any other rate.

This is a very basic result called the No Communication Theorem. It's not in competition with quantum mechanics; it's a fundamental part of it.

The verification of that fact is what this year's Nobel Prize in physics is about.
