Superluminal

Faster-than-light, aka superluminal, space travel was not discovered until centuries later.

The first centuries of superluminal space exploration proved that neighbouring space was mostly desert as other life discovered was in a primordial state.

The first thing to understand about superluminal expansion is that it isn't visible to the unaided eye. The objects that appear to be moving faster than light are emitting radio waves, not visible light.
