This is what Han Solo experiences in the Millennuum Falcon. t: This is the amount of time passing for a moving observer. The faster Han goes, the less time he experiences - even if we see him traveling over light years. Because of special relativity, time dilates or expands outward as the moving observer travels faster and faster. T': This is the amount of time passing for a stationary observer. What this awesome-to-say description really means is that if you were to draw a straight line between an object and the Earth, and a straight line between the object and the Sun, if the angle between the lines is one-arcsecond, then the object is one parsec away – or 3.26 light-years. A Parsec by Any Other Nameįirst coined in 1913 by British astronomer Herbert Hall Turner, the term 'parsec' is a portmanteau of 'parallax' and 'second,' and is defined as the distance from the Sun to an object that has a one-arcsecond (1⁄3,600 of a degree) parallax. The second – the one I choose believe – is far more interesting, because it means that when Obi-Wan sat down across from the wryly smiling Han Solo in that cramped cantina, he met a time-traveling smuggler born at least 40 years before the events of The Phantom Menace ever took place.

The first is that Solo's famous line of dialog was simply a mistake of terminology. A parsec is a unit of distance, not time, so why would Solo use it to explain how quickly his ship could travel? You’ll hear any reputable Star Wars fan point it out eventually: Han Solo's famous boast that the Millennium Falcon “made the Kessel Run in less than 12 parsecs' may have sounded impressive, but from an astronomical perspective, it made no sense.
