I just hope we are not along an interstellar highway. Otherwise, one day spaceships may descend through the clouds and announce:

"This is Prostetnic Vogon Jeltz of the Galactic Hyperspace Planning Counci. As you will no doubt be aware, the plans for development of the outlying regions of the Galaxy require the building of a hyperspatial express route through your star system, and regrettably your planet is one of those scheduled for demolition. The process will take slightly less that two of your Earth minutes. Thank you."

Seriously, not only is it impossible to imagine the vastness and timelessness of space, think of this: In all of that enormity, there is only one being exactly like you.
