Here's the thing, for the past three or four hours I've been having an arguement on MySpace with one of my friends, who claims that my decision to study "The Development of Realism in a Science Fiction Space Settting" is fundamentally flawed due to the unrealistic nature of Space Travel. Now, we've been debating this for a long time now, and I wondered what your thoughts on the matter were? Is manned space travel beyond our solar system (practical or non-practical) or even just existence outside of Earth, based on current technology, achievements and/or possible developments of said technology realistic? Can space travel ever be 'realistic' without being foreseeable? Are we setting our sights too high? For the record, 'foreseeable' as in 'the forseeable future'. I may even use replies from this thread in my research project, if my lecturers give me permission.
