Rockets being passé, China is working on using an electromagnetic railgun to launch crewed spacecraft the size of a Boeing 737, weighing 50 tonnes, into orbit. This remarkably ambitious project is even more ambitious than it seems at first glance.

humans can still function when insane G forces have turned them into jelly right?
While railguns are known for rapidly accelerating projectiles to hypersonic speeds over the short length of a gun barrel, there’s no limit on how slowly they can accelerate something or how long the “rail” part of the railgun can be. Accelerating “slowly” over a long distance is totally possible!
Sure, but it’s gonna require one hell of a long rail…
Make it a circular rail with an off-ramp; like a particle accelerator. Still very ambitious.
That would put the g-forces back in play: the faster you go around the rail the stronger the centripetal force that keeps you going in a circle. If the rail is straight the force only depends on acceleration not speed.
