    Warp speed is mathematically posible, by physics propably not. 100 m/s is about 3XX km/s that is about 200 miles per hour you can do that in car, that is hard to swallow. Hell, the station spanning solar system is much easier to swallow, than a spa eship moving at speed you can get from sports car. A modern figher jets do 600 m/s. Warp speed, dyson sphere, hand others are easier to swallow because they do not introduce such dissonance with reality. Even magic would be more plausible. A low earth satelite moves about 7500 m/s an faster. A prop plane moves faster than 100 m/s

    I know stories are about characters but since you are writing a story about piloting you should at least use elementary physics correctly (I think they teach this in middle school, or whatever is that called). Then in one chapter you actually talk about newton's first law and then you write that there is a terminal velocity in space. You tagged this as science fiction, not fantasy fiction, but science.

    What terminal velocity in space??? Dík they hit light speed?

    In space, you will keep moving even without engine power. Sorry for the rant, it peeves me out. Probably because I used to work in a satellite monitoring center during my studies.

    Come to think of it you are from the US, so the m/s could it be miles per second? That would be better but still nowhere near relativistic velocity. As I said in space engines acceleration is the more important factor than speed.

    I am giving the low world background because of the physics problems. The author mentions speeds like 200m/s 100m/s as the maximal speed of some engines. They are in space and in space, there is no terminal velocity other than the speed of light so engines can keep accelerating until they reach it. In space, the speed is almost of no consequence. The only important is relative speed or delta-v (delta velocity). That is a difference of speed between two objects. If the author wants to express the power of engines he/she should express it as acceleration and not speed. Speed starts to matter only in the atmosphere because the friction of air introduces terminal velocity. To surpass this terminal velocity you need to increase engine power and when the speed increases so does the friction so to keep increasing maximal speed you need to increase engine power. In space, there is no friction and therefore no force that limits the maximum achievable speed of shuttler/ space fighter/rocket/missile/escape pod. The only terminal velocity in space is the speed of light and only when objects is moving in relativistic velocities the engine speed maters. So if there is some engine speed limit it should be in percents of C that is about 2000000 m/s upwards and more likely 10000000 m/s and absolutely nowhere as lows 200 m/s. I like the story but these physics problems introduce in me a such massive dissonance. (That is't how reality works like). The other sci fi things aren'T that problematic but this is to me so fundamental that it breaks me out of the story. And it would be so easy to fix it wouldn't affect the story much and I would be glad to give a much higher rating than what I given now.

    Ok, i wanted to enjoy the chapter but couldn't because of the physics problems. 200 m/s relative to what? If you told it was accelaration i would say ok but as speed it is just 750 km/h that is not even speed of sound. Another one is I thought they were in space in space the only terminal velocity is speed of light. 200m/s is of no relevance in space a Very Very slow speed. Anyway in space more inportant is delta v or delta velocity, which is relativ to same other moving object. If you want to demonstrate power of engines you should show it in acceleration There is nothing in speace that will limit the final speed only after you start aproaching speed of light.
