> Well ... laws of physics are being broken by their ships. They use fusion drives (which don't quite exist yet), Engines not existing yet doesn't break any laws of physics, except possibly those governing material science. The main obstacle for the engines would be to find a material that survives the temperatures involved. The reaction part is pretty accurate, except perhaps that it goes way closer to the theoretical optimums than what our current technology in the area can achieve. > and in S1, transit between Ceres and Eros on a passenger ship doesn't require weeks/months. Transit from earth to Jupiter/Saturn systems are achievable in days. No, it really isn't, even if the show gloss over the travel times (because it doesn't make good TV). It is very, very clear in the books that the distances involved take weeks, months or even years to travel. As for the protomolecule, that one DO break the laws of physics as we know them. But there will be more of that shortly.
