skodabunny: Cubicle Jockey: runner_one: false belief that FTL communications is impossible

Pretend you have a radio controlled FTL ship that moves twice as fast as light. Park the ship at 6,000,000 meters away from you. Point a high-powered optical telescope at the ship so you can see it sitting out there in space. Send a radio signal to the ship to come to you while looking at it in the telescope. Thirty seconds later, the ship appears next to you. During the next ten seconds you can still observe the ship through the telescope before it you see it acknowledge your command and turn it's engines on.

What happens to the ship you can see through the telescope after its engines turn on?
What happened to the emitted/reflected photons during the transit?

I believe that's called "The Picard Manoeuvre". It's in an earlyish episode with Ferengi's in I think.

Cooper420: Rihlsul: How high was the article writer? There's nothing new, he's just musing 'oh man, like, science guys think it works like this, and if it does, like, woah!' type drivel.

Did you read the Nature Physics article? That's the specific experiment.
"Quantum non-locality based on finite-speed causal influences leads to superluminal signalling"

I don't understand this stuff at all, but I do work with some of the world's best people in the realm of quantum physics, computing and encryption.

Wow, it's like you're an authority on not knowing stuff. Congrats!

My reality isn't broken. It ws always shaped like this.
