Why hasn't ET phoned yet?

The big silence: why don't ET phone us?

Could aliens believe that our planet is in civil war? Or are they using some radio frequencies that we cannot hear? 

Element 116 or (Livermorium) hypothesis

Why don't aliens make contact with us? If an alien civilization uses synthetic, ultra-heavy radioactive elements like element 116 (Livermorium) as crystals in their radios oscillation circuits. That makes them able to communicate longer distances without interference. That model makes it hard to hear those radio signals. 

Because their transmitter's oscillation circuits cannot make our receiving circuits oscillate we cannot see alien transmissions. The super-heavy synthetic elements make it possible to communicate over longer distances. 

But those super heavy elements create different frequencies than we use in our radio systems. That makes it hard to see those hypothetical alien signals. 

If we think about alien communication. We should realize that their communication is meant for themselves. Not for us. 

There is a possibility that alien civilizations use neutron balls or some extremely heavy and short-living isotopes like element 116 (Livermorium) as the oscillation crystals in their radio systems. Element 116's existence is less than a second. 

Sometimes it's planned to use in some ultra-secured communication. The use of synthetic isotopes makes it possible to create synthetic radio frequencies that are less vulnerable to interference. But using that kind of synthetic isotope requires that the system dilate time. 

Could aliens believe that our planet is in civil war?

There are writings on the net, where somebody tried to explain cosmic silence. Why doesn't ET contact us? And there is one aspect that nobody mentioned. The aspect is that maybe aliens think that our planet is at civil war. 

When we think about the SETI program and alien civilizations we have one thing that we should keep in mind. Being civilization the aliens must reach Kardachev level 1. That means the alien must solve their internal problems. And that is the end of states in the form we know them. 

So only if aliens are living in a giant planet-size state that they could conquer their solar system. If we think that civilization lives on a planet that orbits a yellow star the solar system is huge. If they want to make bases on other planets that require lots of resources.  And that means aliens must have economical and political support for that kind of project. 

If aliens are forming a homogeneous civilization. There are no national states they might see that our planet is in civil war. In that hypothesis, the key element is that the aliens don't want to choose their side because they are afraid that they rise dictators in power. So they want that we solve our problems before they show themselves. 

This is one aspect of the SETI- program. We know that there are billions and billions of galaxies in the universe. If we seriously think that we are alone even in our galaxy, we are a little bit too lucky. The question is: why we cannot see alien civilizations? One of the answers could be that those civilizations use some other method for communicating than radio waves. 

Radio signals from another civilization are the best way to see technically advanced civilizations. But the problem is that the SETI doesn't find those radio signals. The answer to that question could be that cosmic radio sources like neutron stars and radio galaxies cover those signals. Or maybe aliens use frequencies that are impossible to hear from Earth.
