The problem, as it has been so beautifully stated, is time. Eventually it is conceivable that humans will develop the capacity and technology to go to the stars but there are a few problems that need to be overcome first. Unfortunately, these problems come from this guy named Albert Einstein, you might of heard of him, and the problems that need to be overcome are not that small.
First, according to Einstein, the fastest speed we can possibly hope to achieve is the speed of light (186,000 miles per second). However, if this is true it would still take us three to four years at light speed to go to the next closest star beyond our sun. To make space travel practical this means that we must either go significantly faster than the speed of light, which is impossible according to Einstein, or we must find a way to get around that deficiency. One way to get around this deficiency is to create a wormhole, which in turn folds space/time and creates less distance for a spaceship to travel. The problem is that wormholes are not stable and we really don't know how to make them in the first place.
The other problem we have to overcome is the speed of light itself. As we approach the speed of light, the mass of an object increases significantly. This of course creates more issues. Time is also slowed down in an object moving at light speed. What feels like minutes in the spaceship could literally be years of time passing on Earth. How do you propel something to light speed? Anti-matter could provide the answer but you would have to make tons of the stuff and the technology we have now is quite far away from being able to do that. What materials would the spaceship need to be made out of? In time, I am sure synthetics can answer this call but again this is not going to happen in the near future.
Being an avid Star Wars fan, I truly long for the day when we can have real epic space battles between Star Destroyers and Mon Cal Cruisers. Sadly, this day is well beyond my lifetime. We will make it to the corners of space someday but for right now it is probably best to keep major space travel in the realm of Hollywood.

If the human race stays on its current trajectory in the realm of space travel, then humans will never reach the stars. This is not because of a lack of technology, or innovation. Eventually man will discover the secret to interstellar travel, but by then what will have changed?
As we have seen with the twentieth century, man is capable of rapid development in terms of technology. In the course of less than one hundred years man went from basic flight to traveling to the moon. This gives hope to the notion that one day man will be able to develop a craft capable of delivering him to another star. Some might even call it inevitable. However, space travel since the famed moon landings has been more timid than most space enthusiasts would prefer. The technological race brought about by the cold war made the moon landings possible, and without the cold war, advances in space travel have hit a road black. Without the immense amount of funding from the government, NASA has been unable to produce the kind of results necessary for space travel beyond earth orbit. This is not because of lack of knowledge. The men and women with NASA are some of the best man has ever known, however, without proper funding, some ideas don’t leave the drawing board, or worse, they take enormous amounts of time to come into focus. What is necessary, and what is currently in the works now, is private innovation in the field of space travel. Creating a market and a need for space travel may be a challenge, but eventually companies will take the pressure off of NASA, and man will see a new dawn of space endeavors.
The journey to other stars is so far off, that it’s hard to conceptualize. Seeing man venture out into our own solar system to reside on other worlds may take over one hundred years, provided private industry makes the necessary choices. Assuming this all goes smoothly, and man has made his home on other worlds in our own solar system, then we can start to envision the forward thinkers of tomorrow logically considering a trip to Alpha Centauri.
This is where things get sticky.
When I envision the world of the future, I do it with the help of the great Isaac Asimov. In the world of the future, I strongly feel that robots will be prevalent, if not essential. Already, in our own time man has crafted the post industrial society, and he lives in a comfort unimagined by his ancestors. I feel the same sort of development will be inevitable in the future using advance computers and robotics. In Asimov’s robot series we encounter people referred to as spacers—the first humans to immigrate to space. I feel that the whole of humanity will become much like these “spacer” worlds. In Asimov’s works the “spacer” worlds deteriorate, and have ill relations with Earth, but for my purposes I will use only their general behavior as a model for future human behavior. It may also be said that this is ironic, because Asimov’s “spacers” settled worlds around other stars, but hear me out.
Spacers have long life spans (400 years), and live in extreme comfort with constant aid from robots. Future humans will have no need to travel to other stars, and as the model in my example for the population of our solar system was commercial, this poses a huge problem. With no way to coax people into spending money to go to space, the engines that drive the spacecrafts to other stars will go unmanufactured. After all, if you lived in complete comfort, what would motivate you to give up years of your life living in a cramped spaceship, only to know that a hostile new world awaits you, without the comforts you’re accustomed to? Man will lose the will to explore, and while he may send scientific probes to other worlds, I fear the population of other star systems will not be a reality in this millennium. Of course I hope I am wrong.
The only way a future human, or a “spacer” if you will, will make this sort of a journey, is if it is in a luxurious cruise ship like the one seen in the entertaining children’s movie WALL-E. This of course is assuming that all of the science fiction premises for how humans and robots will behave together hold true in the future. Who knows, maybe robots will develop a taste for adventure.
