Skepticism, Science & Pseudoscience

The aliens in that science fiction novel are extraterrestrial humans. One premise of the novel is that we humans are a star-faring civilization, and we Earth humans are sort of the "poor relations" of the human race. We don't know about the extraterrestrial humans, but of course they know all about us. They get around not by means of space ships, but by tapping into natural forces called "third-order forces" that we Earth humans are as unaware of as cave people were of infrared light. The extraterrestrial humans tap into those third-order forces to transport themselves around the planets and stars by means of some kind of mathematically precise gesticulations that instantly transport them from one node to another. The nodes are confluence points of the third-order forces, and there are several of them here on Earth. Stonehenge is one of those nodes. Not surprising to me; I have visited Stonehenge and there really is something weird about that place, about the feel of the place. The extraterrestrial humans are long-lived; they live several thousand years and they are among us, keeping a close watch on us as they move among us. A very good, highly imaginative and original novel. I read it in the late 1990s and wish I knew where my copy is because I would love to read it again.
