Hey, have you ever imagined how a starship could use quantum entanglement to send instant commands to a fleet across light‑years? I’d love to map out the practical constraints and the wild possibilities.

Sounds like you’ve mapped the core physics, but let me throw a few more variables into the equation. If the ships have their own on‑board quantum processors, you could pre‑program a set of conditional responses to the measurement outcomes, effectively turning each entanglement link into a tiny decision tree. The trick is keeping those processors in sync without exchanging classical data—essentially a quantum dance across the void. It’s a neat idea, but as you said, the real nightmare is keeping the qubits alive over a light‑year. Decoherence would turn the whole thing into a cosmic lottery, and the engineering bill would be… well, it’s the kind of bill that makes a space agency consider going back to good old radio. Still, the thought experiment is a good reminder that the universe loves to keep the “fastest” part of the equation a little slower than we’d like.
