is it really "between galaxies"?

  No. It'll never leave the Solar System unless it happens to surpass the escape velocity of the Solar System. Then, it'll never leave the galaxy unless it surpasses the Milky Way's escape velocity. That would require a tremendous amount of energy. IIRC the Milky Way's orbital escape velocity is something between 300-500km/s (depending on whether you leave the Solar System in a way to take advantage of its forward velocity through the Milky Way or not..)

    I don't think large amounts of force is what you mean here, but energy instead. You can escape the galaxy if you apply a very small force over a very long time, or a larger force over a shorter time.

      Ah yes, you are correct!
