I don't think travel to other star systems will ever be possible. Unless of course we can build a craft that can travel at near light speed. Even then it would take years to reach even the nearest star. The other possibility is a wormhole. These exist at an atomic level, we just need to know how to enlarge them and work out how to keep them open long enough for a craft to go through it. Simple really!

As far as I know, to travel at light speed or near light speed is linearly impossible. According to or restricted to conventional rocketry, as an aircraft's speed increases, so does its mass, and as its mass increases, its speed will decrease. This is a contradiction. Plus, the heat generated as speed increases will be enormous...
So this impossiblity is obvious.
But according to Bob Lazar's explanation, travelling in universe from one planet to another is not that hard for us to understand. Bob Lazar, or Robert Lazar claimed to have served as an expert in propelling technology in the US secret UFO research base known as "S4", where he did back-engineering work trying to duplicate one of the flying saucers kept there. He said the flying saucers in S4 were from part of the exchange program between the US goverment and the aliens(the little grays) from Zeta Reticuli Bi-Star System. The flying saucer he had access to was a disk-like one, or the most reported in UFO sightings. This flying saucer was powered by element 115. Element 115 was bombarded by some particle in the power device and turned into element 116 which would decay immediately and generate anti-matter and gravity wave. The gravity wave can not only offset the Earth's gravity making the flying saucer flying in our sky like sliding from slopes or floating in water, but also can bend space and modify time.
I mean the key is that gravity bends space and modifies time. As we know, the space is not linear. The space is multi-dimensional. We, earth creatures, have our own space and time. It would take light years for us to travel from earth to a certain planet linearly, but it would otherwise take us a much shorter time non-linearly.
All I said above can be googled by the key words Bob Lazar. Most probably you would find this in Wiki.
Anyway, I do believe this.
