Shhh, don’t wake the aliens, warns Hawking

Stephen Hawking has warned against plans to beam radio messages to possible alien civilisations on distant planets. A number of scientists have supported Messages to Extraterrestrial Intelligence.

These would be sent via signals aimed at areas of our galaxy where Earth-like planets and life potentially exist. However, critics have urged caution

Stephen Hawking has said humans should not engage in such communications, as alien civilisations could have the capability to travel to earth and exploit our resources.
