| May 5 at 9:58 | comment | added | Vilx- | Also note that it is one thing to just "get to space" (aka far enough from the surface) and another thing entirely to "get into orbit" (aka circle around the planet without using any extra energy). The latter doesn't automatically happen when you achieve the former. For that you also need to move sideways REALLY fast. And again - if you have another means of counteracting gravity then you don't need to move fast sideways. You can just hover up there as you please. But it will cost you extra energy all the time. | |

| May 5 at 9:52 | comment | added | Vilx- | To really drive home the point about escape velocity: imagine there were giant stairs built from the surface into space. Then you could just climb to space with your own two feet, not coming anywhere near escape velocity. The whole escape velocity business only matters to objects that are accelerated once, and then continue moving with nothing but their inertia. But if you have some other means of continuing to move upwards (like a rocket strapped to your butt), then it doesn't matter how fast you go - you'll get there eventually. | |
