Unobtanium is "the laws of physics allow it, we just don't know if it can be done or how". Niven's Ringworld, for example.

Handwavium is "Yeah, we're ignoring a couple of physical laws for the story". Most FTL drives fall into this category.

Technobabble is "ignore the man behind the curtain". :-)
