What if they are a billion years ahead of us with technology, which is very possible.Even if you could travel at the speed of light or close to it, it would take years to reach the nearest star, some thousands. So which star do you pick to travel to? There's no guarantee that they'll even be there when you arrive as some of what we see today is how things were thousands of years ago. It's a highly enjoyable fantasy, but that's all it will ever be.
Apart from the stresses on the human body accelerating to and decelerating from light speed there is also the small matter of cosmic dust to contend with. Hitting even the tiniest amount would destroy any space craft.
