Pretty straight forward question really. What are rail guns, how do they work and how likely is it that they will replace stage one rockets in the future? Why have they not done so already? Is it feasible? Or would the astronauts just get pasted due to the extreme acceleration?
In: Technology
The most fundamental issue is that either the acceleration would be high enough to turn astronauts into a paste, or you’d have to make the thing miles long. Neither option is really any better than current rocket tech.
