Can a solar sail propel an object to relativistic speeds? The whole point of space travel is to go to other planets at a speed fast enough that the people going there will not be dead or elderly by the time they reach their destination. The only way to do that is by achieving light speed or damn near it. I do not want to board a solar sail vessel bound for Proxima Centauri b (4.22ly) and be dust by the time I get there.
