Your average interstellar supercruiser measures approximately 1 meter wide and 175 long.
Companies demand results, and results demand fast action. And yet fast action over interstellar distances requires years, at minimum, for light to crawl the distance. Anything faster is literally the same as time travel.
So if you’re going to ship an employee in hibernation, you need to get going fast—not only for “results”, but also to avoid, for want of a better term, freezer burn.
So your average interstellar cruiser is hurled to speed by high-energy lasers and decelerated by nuclear pulse. The narrow cross section, droplet shield, and tungsten ablator give the craft a fighting chance of avoiding direct hits from nearly all of the hundred billion or so dust particles it will relativistically encounter.
Nevertheless, mortality rates are still above 70%.
