The space is too vast and the asteroids are not as closely packed as hollywood would have us believe, so charting a path while avoiding them is not that hard at all.No offense but you should read the question first, I said "clearly hypothetically speaking" as in "assuming we can travel at the speed of light", not concerned with the energy requirements. More as in if there is anything in space, or any limitation of physics that would render us unable to keep travelling.
However even if we can gain lightspeed travel, it would still take us a few thousand years to get to the nearest star systems, not too promising when you think about it. This is where traveling through wormholes seem like a more lucrative idea.
Also I am asking(but this may have been more un clear) how long could we travel, meaning without a specific destination and assuming we could keep going forever in space. Is there anything (in space) preventing us from travelling endlessly, basically hypothetically assuming for the purpose of the question that we have advanced enough technology.
