Other Worlds

The Journal of the British Interplanetary Society published a letter in 1986 that has obviously intrigued Paul Gilster for a long while – see his blog at www.centauri-dreams.org and the posting for August 26th 2010). It is all about contact iwth other civilisations – and other worlds. What if advanced civilisations did tend to explore their immediate solar systems, but for various reasons confined themselves only to their neighbours and not to space at large – might this explain why nobody has been in contact with the earth.
