That assumes we have a complete handle on all the natural laws. I don't think this is the case. At the moment we don't know of any way to do it, but as our understanding of the universe evolves we may find a lot of things out that we currently have no clue.
Wormholes, negative energy, and more is more than speculation but less than fact. If indeed there are other dimensions they may be of some use. It is science fictions, but so were waterbeds, submarines, and trips to the moon at some point. To flatly say something is impossible because we don't know how is begging to be proved wrong.
