OPINION LETTERS

摘要

Stephen Battersby discussed the current debate over broadcasting messages into space with the intention of their being detected by extraterrestrial life forms (23 January, p 28). The editorial in the same issue (p 3) endorses the idea.rnAs an astronomer who has been involved in topics relating to the search for extraterrestrial intelligence (SETI) for 30 years, and as a former member of SETI advisory panels, I feel there is an arrogance in the transmission of these messages by small groups who have claimed the right to shout on behalf of Earth without consulting anybody else.
