if it were aliens They already exist, so why haven’t they already tried to contact us? The idea of extraterrestrial life has long fascinated scientists and the public alike, with many theories as to what may or may not be out there in the depths of space, and a recent study has now offered a new explanation for why extraterrestrials have no visited our planet.
According to the British newspaper “Daily Mail”, scientists believe that the messages we sent from Earth have not arrived or have arrived, but there is still time for these messages to return with a response, because we have only sent signals that can be detected from space since the thirties of the last century, so the aliens did not have enough time to receive or respond to the message.
The researchers said the radio waves reached about 15,000 stars and the planets circling them out of 400 billion stars in the Milky Way galaxy, but study researcher Amri Wandel, an astrophysicist, wrote in the research paper that any return message from these objects in case they reached them It takes time to return, only stars within 50 light years have time to respond since the Earth began to spew into the depths of space.
Not only that, but Earth’s first radio signals weren’t sent out into the universe deliberately, which means it would be hard for aliens to tell them apart due to the jumble they’d be in after reaching space for a light-year, because it was It was only in 1974 that we sent out the first intentional high definition transmission The energy of aliens is reported from the Arecibo Observatory.
