Depends on how we look at it. There was a time ships always stuck to the coast line because the ocean was too vast and dangerous. Modern ships just sail right over the waves. Deserts use to be impassable, now we just fly over them.
The universe is going to get a lot smaller when we have billions of self replicating space folding probes traversing the galactic mega clusters.
