"Science Fiction is speculative fiction in which the author takes as his first postulate the real world as we know it, including all established facts and natural laws."
- Robert Heinlein

| Levitating Path | ||
| Anti-gravity metal used to make a floating walkway. |
| He indicated a metal path that struck off into green wilderness, over steaming swamp, among giant ferns and palms. "And that," he said, "is the Path, laid by Time Safari for your use. It floats six inches above the earth. Doesn't touch so much as one grass blade, flower or tree. It's an anti-gravity metal. Its purpose is to keep you from touching this world of the past in any way. Stay on the Path. Don't go off it. I repeat. Don't go off. For any reason! If you fall off, there's a penalty. And don't shoot any animal we don't okay." |
