Uhm, no? He's talking about a constant speed of 1 LY/s, and not an acceleration.

And what he said was nonsense; 10 LY/s is faster than light; you must be a hypothetical particle with some crazy properties and our math really breaks down at that point.

In space you need to think in terms of relative velocities less than c and acceleration. To get a reasonable sense of how far away Andromeda is consider how long it will take to get there, which is just a few years.
