For the sake of pedantry, there are things in the observable universe which are increasing in distance from us by more than 1 light year per year. This means it's impossible to reach them unless the universe's rate of expansion changes. I think the Hubble volume is the region theoretically reachable; limiting acceleration to 1g would limit you to a slightly smaller region (only a tiny bit smaller, I think). | ||
