For this reason as well as for many others, scientists have long sought to find ways in which to explore the bounds of the neighborhood in which the Earth and the Milky Way galaxy ultimately reside. The extant problem that is illustrated though is the fact that there are a number of constraints that provide an ultimate barrier to humans traveling to other solar systems throughout our galaxy. As such, this brief analysis will consider the key issues that constrain mankind to inter solar system travel (and a limited amount of that). Furthermore, by analyzing each of several different viewpoints for how exploration within and without of our own galaxy might seek to take place, as well as analyzing the key weaknesses inherent in each, it is the hope of this author that the reader might be able to come to a better understanding of just what is preventing us from further exploring and/or colonizing other regions of the universe.
The first of these is the fact that the distances that must be traveled are so vast as to be nearly incomprehensible. As a function of this understanding, the reader should come to an appreciation of the fact that distance within the universe is calculated not in miles or kilometers but rather in light years; i.e. the distance covered by a beam of light during the period of a year’s time. To understand just how vast such a distance is, one must understand that the actual speed of light is something approaching 300,000,000 meters per second. As such, the reader can begin to comprehend the actual distance that a single light year actually represents. Furthermore, due to the fact that the nearest star to our own Sun is that of Alpha Centuri, one might assume that it would be most reasonable to visit this one as a means of further exploring our universe and understanding the many nuances that exist within it. However, the fact of the matter is that
