i believe that's close, but not in a linear fashion: its a spherical measurement of 'volume', not distance (a sphere with a radius of one lightyear, so ~3.(something) cubic lightyears)... so for han to pull this off he would need a 'Lint' drive spaceballs to travel at the speed-of-thought so he could occupy every conceivable point within 12x3.5 cubic lightyears simultaneusly
