The best scientist know damn well that they don't know more than they actually know. That is what motivates them to further advance their field of study.

Time dilation would make it possible for passengers in a fast-moving vehicle to travel further into the future while aging very little, in that their great speed slows down the rate of passage of on-board time. That is, the ship's clock (and according to relativity, any human travelling with it) shows less elapsed time than the clocks of observers on Earth. For sufficiently high speeds the effect is dramatic. For example, one year of travel might correspond to ten years at home. Indeed, a constant 1 g acceleration would permit humans to travel as far as light has been able to travel since the big bang (some 13.7 billion light years) in one human lifetime.[citation needed] The space travellers could return to Earth billions of years in the future. A scenario based on this idea was presented in the novel Planet of the Apes by Pierre Boulle. - Source : Wikipedia
A ship that constantly accelerated but didn't necessarily achieve light speed (let's assume they achieved 70% speed of light) wouldn't need a huge amount of fuel onboard. What it would need is a way to collect or obtain energy as it traveled. Solar energy wouldn't work in the spaces between stars. They'd need some sort of way to draw energy from the vacuum or a way of using the supposed "dark energy".
Using the effects of time dilation, a crew could go to another star system and return without aging too much, but on Earth much more time would have passed.
Yes this is true, but at the distances we are talking about you would still age a lot and the flight would probably send you insane due to sensory deprivation or Cabin fever or something.

nice1 said: The speed of light barrier is irrelevant. Two major reasons...
1) We don't even know if they are aliens thus we don't know they if they even require breaking the speed of light barrier 2) Even if they are aliens obviously they have over turned that theory or found a way around it else the advanced craft would not exist
You completely missed Linkymathingys point. Allow my first point to make the light barrier irrelevant alone though. /end

Why do we concern ourselves with civilizations that may or may not exist far, far from us and how we will or will not relate to them when most barely give two shits about unifying our own planet's civilization? I surmise that it would take an alien invasion of some sort to actually bring every human being together.
Thinking we are alone in the universe or some sort of impressive beacon of technological advancement or rationality is sheer arrogance and stupidity. We have a very limited referential and experiential scope, but just because our mind cannot comprehend the notion that somewhere out there in a star ocean comprised of BILLIONS und BILLIONS of planets - which possibly do not even operate by the laws of physics/natural laws we have here, or are even perceptible in the same dimension we are ensnared in, our lack of comprehension is not proof that they do not exist. At this point all we may do is speculate, however to speculate that we are alone is downright foolish.
