I was thinking that aren’t rockets a bit too energy costly i mean that’s why space travel is a bit too expensive so if there was a cables attached to weights and the other end a kind of a grasping thing the cable should be so long so that it does not burn when in orbit around the earth. It must be revolving that would also decrease the energy and the costs The grasping thing would catapult the space ship into the other destination planet just make a virtual diagram or imagine it and tell if you get the picture . It will also make space travel much easier
