Interstellar trips only for science-fiction

A few days a go I was reading about warp speed and how travel fast than the light can be understand that it is under contradiction with relativity.

Science-fiction uses objects that the physics theories says as possible according with other theories that are also unverified. But is nice when you read scifi books or swatch tv shows how interstellar trips can be possible or also intergalactic. But my pleasure in a well when I read the humans, perhaps, never travel far from the solar system. The tech advances can be at a light years distance...

But also we can handle the hope that we are talking from an age like the Ancient Greek says there is no possible to jump higher to the sky...
