A lot of folks mentioning technological advances over the years but we have to remember that they all are “grounded” in some way that makes sense on Earth.

We still have no energy source that makes space travel feasible at the speeds needed. We still have not conquered how gravity needs to work on spaceships (gravity is so important to human health and development). We still don’t have an answer to combating radiation other than burdensome suits that make it hard to move freely.

Our solar system really contains no planet worth settling on other than Mars and we have no answer for how to deal with the cold temp, lack of magnetic field, lack of breathable atmosphere, lack of water, etc. etc.
