Both, your reasons and theirs, cause a decrease in velocity the farther from
Interestingly, any collision with space dust is determined by the laws of
probability as calculated from the rain drop effect equations. The rain drop
effect simply said is that if you run between two doors in a rain storm you
get less wet than if you walk. It applies to space travel as meteor
collisions. Accelerate at one g for 356 days to exceed light speed for the
faster you go the less the probability of catastrophic collision. Star
travel, to be successful, requires a combination of high velocity,
streamlining (minimal rocket cross section area) and electromagnetic methods
for repelling charged objects and avoidance methods to avoid neutral charged
