A group of scientists and entrepreneurs has created the world’s first continuous message beacon to communicate with extraterrestrial civilizations. And for a fee, people can use it to transmit their own messages into space. But not everyone thinks this project is a good idea.
The idea of messaging ETs has been around for a while now, and typically goes by the name METI (Messaging to Extraterrestrial Intelligence) or Active SETI. The basic idea is that, instead of just listening passively for an alien radio signal, we should deliberately try to send messages into space in hopes of attracting the attention of alien civilizations.
