Think of how many religions attempt to validate themselves with prophecy. Think of how many people rely on these prophecies, however vague, however unfulfilled, to support or prop up their beliefs.

Imagine we could accelerate continuously at 1 g - what we're comfortable with on good old terra firma - to the midpoint of our voyage, and decelerate continuously at 1 g until we arrive at our destination.
