Things don’t always look as they seem. Some stars, for example, look like bright pinholes, but when you get them pegged under a microscope you find you’re looking at a globular cluster—a million stars that, to us, presents as a single entity. On a less dramatic note there are triples, like Alpha Centauri, which up close turns out to be a double star and a red dwarf in close proximity. There’s an indigenous tribe in Africa that tells of life coming from the second star in Alpha Centauri, the one no one can see without a high-powered observatory telescope. come to think of it, the Greeks, the Aboriginals, and the Plains Indians all lived continents apart and all, independently, looked at the same septuplet knot of the Pleiades and believed them to be seven young girls running away from something that threatened to hurt them.Make of it what you will.
