| Jul 17, 2018 at 18:40 | comment | added | Jules | "For a Moon-world, its inhabitants can even use Jules Verne-style space cannons to send out probes" ... not significantly earlier than rockets to space became viable technology for us, actually. The most powerful cannon developed during WWII [*] had a muzzle velocity of around 1.5 km/s. Scaling that up to something that could fire a usefully sized orbital vehicle would have taken substantial effort, so I doubt it could have been done by any date much earlier than the 60s. | |
