Quantum entanglement and Einstein's theory of relativity

I have been thinking about this recently. Say two quantum particles, or two clusters of quantum particles, exist in the same universe. 1 is on, for lack of a better term, one side of the universe, one on the other. They are entangled. Because of the distance between them, one is in the future and one is in the past of the observer, who is in the middle, and can somehow see both of them. What would happen in one of the particles moved. because they are entangled they would be moving at the same time, but would the observer see them move at the same time, or would he see one move before the other?

You cannot "see particles in the future".

No. That is not how entanglement works.
 
Quantum entanglement means the particles share a relationship not that they are connected or paired for equal motion.

This should point you in the right direction:http://en.m.wikipedia.org/wiki/Quantum_entanglement

As for the distance thing. Light is relatively constant for most objects in our universe. If the observer was in the middle then they would see objects move together. Now if the observer was next to one of the objects they would see the close object move then the far object. This is the basic understanding of Einstein's theory of relativity.
 
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. Towards the end of the first lecture for the Qiskit Global Summer School 2025, Foundations of Quantum Mechanics, Olivia Lanes (Global Lead, Content and Education IBM) stated...

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!
