[quote=darkwolf687] Well, its not accelerating, because it was moving faster a moment ago. In space, if you give something a push it will keep going until it is affected by other objects gravity or collides, so if you foumnd a great strip of nothingness, you could potentially accelerate the object to light speed without needing to worry about resistance during acceleration, thus taking less energy. Technically, the asteroid is decelerating, extremely fast, rather than accelerating fast, though obvioisly its at a speed that would realistically crush it (But then, FTL would realisticallty destroy ships too.) but its rather harsh to fly in at literally the speed of light and vaporise... well, everythingAnd let me be clear, this object is alien to New Condria's system. Its been brought from outside and is now decelerating. So no Duck, it doesnt matter than your moon is half the size... well, actually it does because it means less gravity on the asteroid than in Sol systemI'm going to be quite honest here, I dont defend the 70% asteroid myself. Its been a while since I passed GCSE physics. I defer to more informed judgement on what the speed of the asteroid should actually be [/quote] Wait, so you already had this asteroid coming in from presumably another solar system? This attack was planned for about a decade or so then, wouldn't we have realized a MOON flying towards the system?
