University of California scientific team: Aliens expected to answer Earth’s radio calls as soon as 2029 | Big Vision

For over 100 years, humans have used radio waves to communicate on Earth Is there any chance that these waves will leak into space and be intercepted and answered by aliens? A team of scientists at the University of California believe that aliens could contact Earth as soon as 2029.

Scientists have recently traced the path of powerful radio transmissions from Earth to multiple distant spacecraft and determined which stars, and any surrounding planets that might support alien life, are best suited to intercept the messages, as PopSci reports.

The research team created a list of stars that will encounter signals from Earth within the next century, and found that an alien civilization, if any, could send a reply message as soon as 2029. Their findings were published on March 20 in a publication by the Astronomical Society of the Pacific.

Howard Isaacson, an astronomer at the University of California, Berkeley, said: “This is the famous idea of ​​the astronomer Sagan (Carl Sagan) during his lifetime. “In 1997, “Contact” was based on Sagan’s story. (Link). ), it describes that a scientist involved in the “Search for Extraterrestrial Civilization Project” (SETI) found evidence of aliens on a planet 26 light years away from earth, and chose to send radio wave signals, Actively engage with each other.

The research team calculated that, in 2002, NASA sent radio waves to the “Pioneer 10” probe through a normal communication protocol. If there is alien life to provide an answer, it can be sent back to Earth in 2029 at the earliest.

Previous transmissions to Voyager 2, Pioneer 10 and Pioneer 11 have all reached at least one planet.
