Gerrit Verschuur is a well-known professional radio astronomer, who has published a dozen books including, most recently, The Invisible Universe (3rd edition – Springer, 2015). During his research career spanning half a century he was the first to carry out a search for radio signals from extraterrestrial intelligence (ETI) that had a chance of actually detecting another civilization. With the cooperation of Carl Sagan, Verschuur published the results in the journal, Icarus in 1973. Since then, while writing close to 100 technical papers based on his research into the nature of interstellar medium and popularizing astronomy through nearly 100 magazine articles, he continued to ponder the issue of whether ETI actually exists. To this end he embarked on a journey of exploration into more esoteric realms of human experience in the search for evidence that ET is in contact with human beings. His adventures lead to experiences in human-dolphin communication, experiments with sensory deprivation, and interviews with individuals who claimed to have made contact with ET. As a result of his experiments he was forced to consider the possibility that our position on planet earth may be unique in the Galaxy and our first responsibility, even as we consider how to make contact with aliens, is to make sure that our species continues to survive. In this regard he draws upon the subject of several of his other published book including Impact! The Threat of Comets and Asteroids (Oxford, 1996), Hidden Attraction: The History and Mystery of Magnetism (Oxford, 1993) and Cosmic Catastrophes (Addison Wesley, 1978).
