Do you know about the new signal for aliens?

Astronomers have done so much research. When thinking about astronomy, the first thought that comes to scientists and everyone with a scientific mind is aliens.

It is natural to have doubts and curiosity about whether humans like us or humans who are different from us live in this universe. How to find them? How to see them? Are they there? Or not? Interestingly, various questions and discussions arise in the world of knowledge.

American space researchers embarked on research into whether humans live on other planets. They chose to send signals from Earth, thinking that if people on other planets received them, they would communicate with us.

In 1960, a 21-centimetre wavelength was sent from America. After travelling 100 trillion kilometres, these signals can reach specific planetary groups after travelling 11 years. If any humans live in these blocks, they will be able to answer this after these 22 years because these signals travel from Earth for 11 years and it will take them 11 years to receive them and send them back.

Perhaps there are thinking beings there and if they have a conscious receiver, it is possible that they could have answered this. The scientists who did this thought that they might be like us or have more knowledge than us, but the answer has not come till today.

It is very difficult to predict anything in advance. When scientists chose the 21-centimeter wavelength, they did it with a purpose. This is the wavelength of the signals sent by hydrogen atoms. This happens every time the particles inside the hydrogen atom change this magnetic moment. This event is repeated once every 11 million years in each atom.

Since hydrogen atoms are everywhere in the universe, this event is happening somewhere in some place every moment. Therefore, signals with a wavelength of 21 centimetres are constantly coming from some part of the universe. The entire universe is full of hydrogen.

 Astronomers who have received signals from hydrogen atoms are monitoring what is happening around us. Why did scientists think that people on other planets would listen at this wavelength?

 People who have reached our level or a level of development beyond that will show interest in the universe. They will receive hydrogen signals with a wavelength of 21 centimetres. So, scientists thought that they must have a receiver connected to this wavelength.
