  1) you also need time decelerate 2) speed of light is a hard limit, you cannot keep accelerating and you need more energy the closer you get to that limit

    > 1) you also need time decelerate No that would be a waste of effort. A flyby mission definitely makes the most sense. The 3.5 years are with deceleration though.

      You mean flyby at almost the speed of light? For interstellar travel, I think usable flyby speed is almost the same as stop and look around speed.
