Interstellar propulsion

Somewhere.. something incredible is waiting to be known, Carl Sagan

Can we advance beyond Type I civilization yet? Are we technically skilled to acquire another star system? I am sure you all admire movies with the warp devices traveling from one-star system to another. Today, even a small kid is familiar with the concept of an expanding universe, so did we ever wonder how these spaceships are traveling with a speed greater than light speed? The concept of warp drives exists theoretically and is theoretically proven. If we acquire that kind of technology, wouldn’t we be the species leaving its trace forever by expanding its habitats? Let’s talk about how engineers see the possibility of an interstellar travel breakthrough.
The journey covered by voyager (which is well testified) traveled from earth to pluto was in the span of 13 years and it is the fastest one out there. But imagine traveling to another galaxy perhaps another star system. The closest known star system to us is Alpha Centauri and it would take centuries to reach there if we travel with the speed of current Voyager, moreover, it used gravity assistance of other celestial bodies to get there. Well, years is not the only issue here but how about the power to operate propulsion system we would need to reach there. In the deep space exists no gravity assistance, neither sunlight.
With the state of the art of propulsion system, the…
