The furthest a human ever went :/

  ... and, I am afraid, ever will. One just needs to realize that life (on Earth) critically depends on being able to increase the entropy of the environment. A spaceship (smaller than a planet) simply cannot provide an environment that could support such need for an extended period of time.

    Except for the fact that we continuously discover new energy sources and new ways to store information. There are indeed fundamental limits imposed by thermodynamics, but something as crude as space travel is not limited by them. Rather the limit is the immaturity of our technology. And a space ship is not an isolated system: it can shed waste heat, and as long as it has a power source, the entropy of the living space can be controlled.

      > Except for the fact that we continuously discover new energy... Is that really a fact? Is it guaranteed to be true in the future? Past discoveries seem very lumpy and unpredictable to me.

  The furthest people have ever been was actually when Apollo 13 swung around the moon. A nice consolation prize for those guys
