We will never get to the stars with this method. I have absolutely zero trust in any government keeping up with a sustained multi decade effort supporting people who can’t vote because they’re billions of miles away.
Suppose that we suddenly get a message from outer space that there is another planet with billions of ‘people’ on it and they want to communicate with us.
Democrats would fall all over themselves trying to get there and sign them up to vote!..........
Either figure out a way to create portals (bend space/time) or fuggedaboutit.
This will cut the trip to the nearest star system from 100,000 years down to just 90,000 years. Oh, and then add on another 90,000 years for the return trip to earth when the crew finds out that the star system has NO habitable planets.
