Because of special relativity, it wouldn't even be 5 years on the ship.
A massless drive would open up exploration of the galaxy within the life time of a human being. Even though on Earth, thousands of years would pass, so it's kind of a one-way exploration nevertheless.
- api 6y agoWould you still get time dilation with a warp drive? Are you actually "moving?"
- bhaak 6y agoIf by "warp drive" you mean a drive that would be contracting spacetime in front of the ship and expanding it behind, then this ship wouldn't be subject to time dilation. As it is not the ship that is exceeding the speed of light within a local reference frame (the "warp bubble) but the spacetime. But the feasibility of such a drive is purely understood at the moment as it seems such a drive would allow for causality violations.
