    Question Possibility of manned interstellar travel

    Many people are optimistic that plans such as the Breakthrough Starshot can be feasibly done within a generation, but do you think we can ever send humans to another star?

    There are no doubt numerous challenges that come with a manned mission, so what are some of the greatest barriers we will encounter? With the time and resources humanity has left, are there any challenges you doubt we could surpass?

    Ever is a long time. And we may do so centuries from now. But the challenges are massive. Interstellar travel in person would require bringing your own life supporting ecosystem, plus whatever technologies you need to maintain it artificially. That means mass, and lots of it. The energy required would be enormous.

    Basically, you'd need a mobile, self sustaining civilization. Something we have not been able to build even in our own Solar System. Then you'd need to move it an unimaginable distance either at problematic speeds, or over a problematic time period. A means of getting across such a distance within historical time has also not been invented yet.

    The topic has been discussed on Cosmoquest a fair bit over the years. Here are just four threads dating back to 2005 (and I'm not suggesting we don't discuss it here but...the challenges noted in 2005 are still the same. As are the technologies in play...)

    ETA: But thanks to Kepler, et al, the target list has grown!
