In the 1970’s we send space craft on a journey to leave the solar system (the voyager probes). They are the fastest thing we have ever made and they still haven’t made it out (one of them might have just got there, but scientists still aren’t sure). in 40 years. I thin it will be a long time until humans can get big enough spaceships to live on for more than 40 years.
I think we need to develop a lot of other technology or a larger entire population style travel systems becasue to go such long distances takes such a long term. Eventually we might, but I don’t think any of us will be here to see it
