Hello all, I would like some insight regarding a creative writing piece I am working on. As I stated on my topic this is not homework, it is an independent science fiction piece I've been working on for some time. I apologize in advance if this is in the wrong forum, and would appreciate direction to the proper forum if it is in violation of forum rules/guidelines. My conundrum involves the use of long range sensors on a ship that is moving faster than the speed of light. Personal disclaimer: I have a general knowledge of physics but am in no means an expert and am taking fictional liberties (many apologies!). To be more exact; my fictional spaceship is traveling inside a pocket dimension which allows it to then move faster than the speed of light through conventional means (Ion engines). I thought this to be the most 'realistic' form of FTL travel that allows my ship to circumvent traditional laws of relativity. I also figured that it neatly avoided the issue of running into a speck of dust at several times the speed of light (big bang part 2?). So my problem is that I require a way for the ship to be able to use spectography to analyze star systems it approaches, while inside of the dimensional bubble. This ability is vital to my work as it is key to conveying the main character's growing sense of futility in his mission, which he hides physically from the rest of his crew. I cannot simply have the ship drop out of it's 'bubble', as it's already established that it takes it approximately 15 months to generate enough power to create this effect in the first place. Also the ship cannot afford to constantly drop in and out of spin drive because of concerns involving maintenance and economy of resources. I apologize for being so vauge, but I am looking at a potential publisher and can't afford to be too liberal with the details of my work. Also I realize that I am taking several liberties with the laws of physics in general, but I would like to limit those liberties and establish every technology and aspect of my fictional ship in as much reality as possible. With that in mind, does this community have any thoughts on how a ship operating inside a pocket dimension might be able to still conduct long range spectrography? I would really like to avoid 'magical and mystical' futuristic technology that just makes stuff work. Seems like a cop out to me. Thank you in advance.
