As resistance and gravity are both negligible in space, the critical issue isn't the ability to push a craft in the right direction but instead the amount of time needed to arrive. If we consider the nearest star as a potential - Alpha Centauri - at 4.3 light years it would take 80,000 years using extant technology. (And this is "next door")

So to really "get there" would require a significant breakthrough in the realm of physics --- yes, the "wormhole" idea, or some other quantum-mechanical contrivance that circumvents Newtonian mechanics, or time, or both. Energy and/or time are the main issues. In order to take enough fuel using current technology to propel and to stop (it ...
