For example, we usually talking about Earth as very ordinary world, assuming, we are not special.
For most parameters, Earth ordinary. But exists at least one parameter, which is specific.
What I mean, Earth in Galaxy region, where density of interstellar matter is very low, so low, for example Bussard engine could not work.
But for example in central Galaxy region, density of interstellar matter is few magnitudes larger, Bussard engine might work, and it is very real tech for interstellar travel with speed close to speed of light.
Sure this have some consequences, for example central galaxy regions considered very active for star bursts and even explosions, so they have not billions years of calm life, they really dangerous for life as we know it.
So, we are ordinary world and not ordinary at same time. From our current science view, we are in void, with low matter density.
Between us and other part of galaxy, exists huge (for us) void, which is not easy to cross.
