If "everything" is science fiction until our understanding advances, then why not wait until we have teleportation and faster-than-light transportation? I think we have no basis to assume that everything we can imagine, such as faster than light travel, is certain to be realized sooner or later. Some things are impossible. Granted, we can never be 100% sure that something is impossible, but we can be 99.9999% sure about many things. Regarding your original statement, it seems to me that if we are ever able to colonize planets on distant stars, there are probably millions of planets that would be nice to live on. Places either similar to earth, or capable of being terraformed. So why bother going to one that is too hot or requires extreme technology such as anti-gravity just to live on it?
