Aliens have not contacted Earth
The new study has now offered a new explanation for why aliens haven’t visited our planet, because there is no sign of intelligence here.
The researchers said that the radio waves reached about 15,000 stars and planets, out of the 400 billion stars in the Milky Way galaxy.
Study author Amri Wandel, an astrophysicist at the Hebrew University of Jerusalem, wrote in the paper that any return message from aliens takes time to return.
The first radio signals were not broadcast in the depths of space
He explained that basically, only stars within 50 light-years have time to respond, since the Earth began broadcasting in the depths of space, and not only that, but the first radio signals of the Earth were not deliberately sent to the universe, which means that it would be Difficult for aliens to distinguish them because of the jumble they would be after they reached space for one light-year, and it wasn’t until 1974 that we sent the first intentional high-energy broadcast to aliens with the Arecibo message.
However, there have since been plans to send another message in the form of a beacon in the galaxy, and it will include a drawing of DNA and the solar system, and a diagram of what a male and a female look like, but it will also contain a lot more information about mathematics and basic science than the Arecibo message.
And all this is evidence that extraterrestrial life did not have enough time to respond to us, the researchers say, that there must be more than 100 million technologically advanced planets in the Milky Way for civilization to have even received one of them.
It is believed that his theory indicates that there are no intelligent aliens within 50 light years from Earth, but this does not rule out their presence somewhere in the universe. The reason may be that they are waiting for Earth’s technological signals to reach them, or that their response is still on the way.
He defines the potential for contact as an opportunity to find a nearby civilization close enough that it can detect the first radio-sphere emissions and send a probe to the solar system today, Wandell said.
He added: It was found that the probability of current contact with Earth is very low, unless civilizations are very abundant, since the radio envelope expands over time, so does the possibility of contact.
