Jumping into hyperspace to make a lightspeed escape is typically something normally associated with the Millennium Falcon’s capabilities. Our technology, sad to say, is far from the point to where we could safely travel at such speeds. Therefore, even though there are plenty potential hotspots for investigation for life, civilized or microbial, habitable conditions, or ancient records of such…..or all of the above, sending man out to explore the unknown to an appreciable distance beyond our home is…complicated, to say the least. Honestly, the relative difference in time frame was a confusing point in space travel for me in the Star Wars universe, and while we can write it off in fiction, real-world applications aren’t as privy to poetic license.
The classic textbook example is that if you’re on a X-lightyear trip to a galaxy far, far away, a drastically higher number of years would occur on Earth relative to the ship’s crew. The difference in “time” passed poses a variety of societal challenges; even if we were to establish a base and form communication, to what end is it valuable if friends and family could even be dead in what you consider to be a trip of a few years? I don’t know if there’s ever going to be a right answer.
