We're never getting out of this solar system, are we?

  Haha, never doubt science! You never know. Centuries ago, humans then would have regarded today's technological feats as impossible. But, yeah, I don't think we are ever leaving the Milky Way. Lol

  Unless we go extinct, I would assume eventually it will happen. Maybe in tens of thousands of years.

  If we don't wipe ourselves out in the next 1000 years, I think we'll launch manned missions to other star systems that make it to their destination hundreds and even thousands of years into the future, with their original crew still alive.

  Physics are not so bad for interstellar travel. We just need a an engine that accelerates our space ships with 1g constantly. With that, we would reach something like 80% lightspeed after one year. Exactly in the middle between start and destination, we would turn the ship around and start accelerating towards earth again. A trip to Alpha Centauri could be done in less than 4 years ship-time. Earth-time would be some years longer. 1g constant acceleration would be quite comfy for humans. The only thing we need for this plan is the constantly running engine. I propose to bend space-time in front (or behind) the ship, for it to keep falling forwards.
