Stellaris inspired post #1. 
An orbital ring is a concept of an artificial ring placed around a body and set rotating at such a rate that the apparent centrifugal force is large enough to counteract the force of gravity. The structure is intended to be used as a space station or as a planetary vehicle for very high-speed transportation or space launch.

Because the cable is spinning faster than orbital velocity, there is a net outward force that is countered by internal tension within the cable. This resists any attempt to bend it and allows it to carry loads. In typical conceptions, a motorized platform is placed on the cable that runs in the opposite direction at the speed that makes it appear stationary above the ground. Above Earth's equator, a platform running at 9.5 km/sec in the direction opposite the cable will appear stationary and allow a cable to be lowered to form a space elevator. This elevator is only perhaps 500 kilometres (310 mi) long, which can be built with existing materials.

we are so early

WE ARE SO EARLY!
i dunno wtf is happnin here though
