Video: People will contact aliens in 2018

An organization called Messaging Extraterrestrial Intelligences (METI) will try to send a message to communicate with aliens in 2018, although this could endanger the Earth.

The most endorsed message includes physics and mathematics.

According to CNET, the most endorsed message includes physics and mathematics because it is a form of alien knowledge that is as fluent as human.

However, many scientists, including Stephen Hawking, fear that sending messages may put the Earth at risk.

Previous attempts to communicate with alien civilizations include: sending alcohol recipes, ads of Craigslist.
