:P
Yup.
I quite agree that colonization via travel across the space between the stars is unrealistic given our present understanding of physics.
I just find it highly amusing that some of us think we have a full and complete understanding of physics, especially since with our present knowledge quantum mechanics and relativity contradict each other. Since we know (believe) that both accurately describe reality, it seems pretty obvious there is some deeper level of reality we haven’t yet understood in which they are not in conflict.
