Starlight Could Be a Vast Alien Quantum Internet, Physicist Proposes

This seems to be based on a misunderstanding of the nature of quantum entanglement. It does not mean that anything affecting one of the entangled particles has an effect on the other one.

Rather, once two particles have been entangled by essentially syncing the vibrations in their atomic spins, a measurement made on the quantum state of one of them implies the quantum state of the other, even if moved far away.

Imagine spinning two baseballs in space so that one spins the other, which then rotates the opposite way. If we move ball 1 away from ball 2 and only look at 1, we will still know which way ball 2 is facing based on which way 1 is facing. At least until random fluctuations and gravitation effects cause our ”particles” to disentangle (lose coherence).
