Mark: How many seconds are there in a year? If I tell you there are 3.155 x 10^7, you won't even try to remember it. On the other hand, who could forget that, to within half a percent, pi seconds is a nanocentury.
Somebody else: Huh? Who cares.
Slowboating is a science fictional verb/slang to a theoretical means of traveling between star systems known as Multi-Generational Space Voyaging. Moving slower than Light Speed. This can pertain to humans who essentially are living and dying per generation during a multi-light year voyage or individuals whom are frozen and waiting time of their arrival at their destination, which could take centuries if not longer.
