Yeah but the gyro-scoptic affect would make it really hard to turn when the weapon was charged to fire making it a bugger to aim for a large enough gun for recoil to actually matter. Generally the impulse from projectile shells in space would be low enough to be insignificant anyway, less than the force the retros on the other side of the ship should be able to counter anyway. Perhaps good for a smaller ship designed to sit at the end of a battle with a massive spinal mounted weapon.... but you will still get recoil when you are it! Momentum conservation still applies!

I mean that simply, we may find it easier than we thought. Lots of discoveries happen by accident and scientists trying a completely unrelated experiment suddenly find they accidentally managed to create a gravametric field instead of a magnetic one or whatever. Just call it Quantum!

Actually projectiles have a longer range than lasers as they can curve with gravity. Lasers also have major problems at long range with thermal blooming and atmospheric absorption/deflection which can all cause the beam to miss.... let alone more extreme conditions.

Any science to support that? Achieving 30m/s requires a fair amount of energy, so at the very least its going to take some time. Also normal rocks with far less gravity manage to hold a thin atmosphere, Pluto manages to hold a thin atmosphere and has far less surface gravity over a prolonged period. At the end of the day it takes a lot of energy to accelerate something to 30m/s so the atmosphere would survive at least to the point where it had absorbed that much energy which would depend on it's distance to solar objects.

Yep, which means the atmosphere is slowly going to bubble off. How quickly is the question. .03 km/s is still 30m/s which is a fair velocity so its not just going to go POP and disappear off into space. I reckon if someone dumped an earth like atmosphere on a magic rock like that, you'd probably be able to survive for at least a few years before the atmosphere boiled off.... assuming you could survive the low atmospheric pressure.

Not sure if that is correct. If you are talking about holding an atmosphere for thousands of year sure but at least short term or with replenishment it should be possible, although the atmosphere would be far thinner than a larger planet's atmosphere.

Already been though all this in a game a long time ago. The 'truth-stone' ended up a lot more complicated. It involved a magically shielded chamber (full anti-magic negation) with several spells that worked through this zone - Geas - Must answer any question directly and to the best of their knowledge - Dispel Curse - Heal - Restore Mind (To undo cases where people had deliberately or accidentally had their memory altered) Truth Seeker - To help deal with cases where someone might not know what they were saying was a lie. So yeah, a simple truth spell isn't all that effective

Perhaps the water is what triggers them from 'travel' mode to 'attack' mode. So if they come into contact without actually been inside a person, they would switch into attack mode.... then die on the floor. Would give them a reason to fear water that isn't inside what they want to feed on. Also this means any area with decent levels of humidity would be pretty much immune to them as their small size would mean even humidity would cause an issue.

No, because like warp drive, its not really FTL. True FTL communication is not possible, like true FTL travel as it would require infinite energy. However pseudo-FTL is possible as proven by the expansion of the universe, either via wormholes, Quantum Tunneling or warp.
