    Smarter people than me on the internet calculate that at constant 1g you only need 2.5 years to get very close to speed of light. So I guess you accelerate fast enough and reach ‘almost speed of light’ very early in your travel and total time is almost as if you traveled at speed of light the whole time.

      The main advantage of keeping accelerating when you’re at >90% of the speed of light is that it means you arrive faster in subjective time. You could take 160 years to get there and use ten times less fuel (or thereabouts), but the subjective travel time would go up by decades.

        I think having constant gravity on the ship during the entire flight is also a big plus. Designing a ship where you can live in 0g for years and in 1g for years would be like designing two ships in one.

      Not that smarter when they forget you’re running out of gas by the Oort cloud. Gotta spread christianism capitalism there and build a petrol station before we go further.
