Before you can ask yourself "is space travel possible?", you first must ask yourslef "what is the nature of space?". We don't know for sure that space really physically exists at all, it may just be a concept that we associate with the changes in the world around us, and use to chart the progress of those changes, a concept we have become so dependant on that we view it as something physical that can be seen or changed or altered. The fact is we don't know for sure that space is a physical thing at all, it may just be all in our heads, a psychological crutch, if you will.

On the other hand maybe it is. And then you have to wonder what it's physical propertys are. Is it a dimension, a fourth axis on which we are constantly moving? Or perhaps it's some other physical thing. The fact is, it is at our current stage of thought impossible to prove or disprove even the EXISTANCE of space, let alone weather we can alter it's course.
