Aliens. The indispensable subject of science fiction movies, ‘aliens communicating with humans’, is this time under the lens of science. ‘If aliens really exist, why haven’t they tried to contact us?’ Scientists looking for an answer to the question have come up with a new theory: Maybe we are not smart enough!
According to the article written by astrophysicist Amri Wandel, we earthlings may not be an advanced enough civilization to attract the attention of the intergalactic species. Wandel hypothesizes, Fermi Paradox,
The scientist from the Hebrew University of Jerusalem underlines that we have been sending radio signals to the universe since the 1930s and states that these signals have reached only 15 thousand of the 400 billion stars in the Milky Way.
On August 15, 1977, a 72-second-long radio signal was detected from space within the scope of the SETI project. The astronomer who detected the signal thought that this might be the first message from an extraterrestrial civilization, and as a result of his surprise, he wrote ‘wow’ on the paper containing the data.
It was 1974 when we sent the first high-power broadcast to aliens with the Arecibo message. Additionally, Earth’s first radio signals were not sent into the cosmos as part of a conscious project. So even if the signals reach an intelligent life form, the signals may be too corrupted to be detected by them.
All of this may indicate that extraterrestrial life hasn’t had enough time to respond to us. What if the reason we haven’t received an answer yet is because we are not a civilization that meets the aliens’ criteria?
Focusing on this possibility, Wandel hypothesizes in his paper that life in our galaxy may be more common than we think. This means potential extraterrestrials have a hard time choosing who to contact.
The paper, which has not yet been peer-reviewed, suggests that Earth is perhaps not technologically advanced enough to be worth the aliens’ time, and thus receives little attention from earthlings. In other words, if aliens exist, they’re probably more interested in finding signs of technology than life, and that’s why they may have overlooked us all this time.
“Contact probability is defined as the chance of finding a civilization close enough to be able to detect the earliest radio emissions (radiosphere) and send a probe to reach the Solar System at this time,” said Wandel, adding that the current probability of contact for Earth is very low unless intelligent life is common in the universe. reached its conclusion.
Saying, ‘As the radiosphere expands over time, the possibility of contact also expands,’ Wandel is of the opinion that the Contact Period was between a few hundred and a few thousand years.
Although there is a theoretical possibility that there are extraterrestrial intelligent beings in the universe, the fact that we have not yet encountered these intelligent beings is a paradox that the scientific world has been working hard on. This is called the Fermi Paradox, and Wandel offers a new answer to the Fermi Paradox with his paper.
