Travel between star systems - which may someday be do-able but given that even our closest star is 4.6 light years away it is something that will require technology and resources that we can only dream of by today's standards.
It is also a very big subject in science fiction; the rapid transit between star systems by faster-than-light travel; Star Trek, Star Wars, and Mass Effect are examples.

While Voyager 1 is technically making interstellar travel, at the rate it is going, it will take more than 72,000 years from now to do so.

Get the Interstellar Travel mug.A framework for moving between stars—whether by generation ships, suspended animation, or (if possible) FTL. Theory of Interstellar Travel asks: How could we actually reach other stars? What would it take? Generation ships (multi-generation voyages), sleeper ships (crews in hibernation), seed ships (automated colonization), or (if physics allows) FTL. The theory explores every conceivable way to go interstellar, with the engineering and human costs of each.
Theory of Interstellar Travel "The nearest star is four years away at light speed—but we can't go that fast. Interstellar Travel theory explores the alternatives: generation ships where great-grandchildren arrive, sleeper ships where you wake up centuries later, or maybe, someday, warp drives. The theory doesn't promise easy answers; it just asks how hard the answers might be."
