To add to that, we can, with our current technology, for a handful of billion dollars send a rocket to Andromeda that would arrive in 10,000 to 65,000 years.
But if we want the rocket to be anything more than a pitted lump of metal when it arrives, say, sending information back, operating scanners, etc, the price jumps exponentially (assuming any useful technology we build could still be usable even after 100 years in deep space).
It ultimately boils down not to the "Can we do it", but "Is it WISE to do it", and that is always either the more difficult or more expensive question to answer.
- credit_guy 4y ago> send a rocket to Andromeda that would arrive in 10,000 to 65,000 years Andromeda is 2.5 million light years away. You are probably thinking of sending some vehicle to the closest star, Proxima Centauri, which is just about 4.25 light years away. This is the same as 270000 AU away; Voyager 1 has been launched 45 years ago, and it's at 157 AU from Earth, which means it traveled at an average speed of about 3.5 AU/year. At this speed it would take it 77000 years to get to Proxima Centauri.
