600 light years?

IMO, inter-stellar travel will be impossible. Even if we could travel close to light speed - which also raises the question of how to stop/navigate a vehicle traveling at that speed - I don't see how we could maintain life for 600 years in such a vehicle.

If you were traveling close to lightspeed, ship time would/could be significantly less than 600 years.
