The Search for ET Causes a Big Split Among Space Scientists
The schism pits the traditionalists, who believe humans should only look and listen for extraterrestrials to avoid tipping off evil aliens, against a rebel faction that wants to broadcast messages to intelligent beings, assuming they are altruistic.
“Are there intelligent beings out there? We don’t know, but the only way we can find out is if we look,” said Douglas Vakoch, who founded METI International in San Francisco after the SETI board voted in 2014 against beaming messages into space.
