Why haven’t aliens contacted Earth yet? A study answers
if it were aliens It already exists, so why haven’t they tried to contact us already? The idea of intelligent extraterrestrial life has long haunted scientists and laymen alike, with many theories about what might or might not be out there in the depths of space.
In this regard, a recent study has now provided a new explanation for why aliens have not visited our planet – because there is no trace of satellite intelligence here all this time to receive the message or respond to it.
The researchers said the radio waves reached about 15,000 stars and planets revolving around them out of 400 billion stars in the Milky Way.
Additionally, study author Emre Wandell, an astrophysicist, wrote in the paper that any returning messages from aliens take time to return.
Essentially, only stars within 50 light-years have had time to respond since Earth began broadcasting deep into space. Not only that, but Earth’s first radio signals were not deliberately sent out into the universe, which meaning it would be difficult for aliens to tell them apart. , due to the confusion they will be in after being in space for a light-year.
“It wasn’t until 1974 that we sent the first intentional high power transmission to aliens with the Arecibo message, however since then there have been plans to send another message in the form of the Beacon in the Galaxy (BITG) message,” Wandell said.
Wandell says there must be more than 100 million technologically advanced planets in the Milky Way for a civilization to have received one.
Wandel’s theory is believed to indicate that there are no intelligent aliens within 50 light-years of Earth, but this does not rule out their presence somewhere in the universe, and the reason may be that they are waiting for technological signals from Earth to bring them reach, or that their response is still forthcoming.
“The contact potential is defined as the opportunity to find a nearby civilization close enough to detect the first radio emissions (radiosphere) and send a probe to the solar system today,” Wandell wrote.
