This is a big step for SETI-program

 




This is a big step for SETI-program


NASA is starting to fund a Harvard University project to hunt for the technical civilizations. And this thing tells that the SETI (Search for Extraterrestrial Intelligence) is taken more seriously. The new exoplanet observations are increasing the pressure and hope to search for the extraterrestrial technically advanced civilizations. The search contains two main roads.


-----------------------------------------------------


Two ways to search the alien civilization


1) Attempt to find the radio signals from other solar systems. The ideal version of that kind of contact is to find the synthetic frequencies, which can be identified by causing artificial transmission. Another version is just searched the alpha-emission of the hydrogen, and hope that the alien would follow that frequency. 


The idea is that because hydrogen is the most common element in the universe, also aliens would listen to it. And the idea is to use that frequency as the call-channel. 


But there is a problem with that kind of attempt. And that is that alien must separate the message, what is sent from the radio telescopes by human researchers. So there is the possibility, that aliens would not detect the signal, because of the background radio noise. And here the question is should we attempt to make contact actively. That means active radio transmissions to the stars, where the suspected alien civilization is living. Or should we just listen? 


2) Attempt to find the "fingerprints" of the technical civilization. Those things are pollution and some other chemical changes in the environment, which would be suitable for alien lifeform, which is similar to us. 


But the problem is finding a suitable planet is difficult, and there is a possibility, that the aliens would not use the combustion engines anymore. So the thing is that this kind of search would take an extremely long time because the telescopes should observe the area near every known star. 

------------------------------------------------------


If we make contact with aliens, we don't know a thing about those species


And then we must realize one thing. Facing alien civilization would be at the same time fascinating and frightening experience. The thing is that aliens would not be like humans. They might look like humans, but they are formed on a different planet. And that thing makes this kind of contact dangerous. 


The culture of the aliens might be different, what we have, and that means that this kind of thing is making the SETI-program so interesting. Everybody wants to see aliens, but the thing is that at that moment we would see that we are only one civilization with other civilizations. But would that thing revolutionize the society of the human race? Maybe we would turn to unite and the wars will be ended, but the thing is that this kind of thing is pure hypothesis, until we are making the first contact with alien civilizations.

Plasmonic waves can make new waves in quantum technology.

"LSU researchers have made a significant discovery related to the fundamental properties and behavior of plasmonic waves, which can lead ot the development of more sensitive and robust quantum technologies. Credit: LSU" (ScitechDaily, Plasmonics Breakthrough Unleashes New Era of Quantum Technologies) Plasmonic waves in the quantum gas are the next-generation tools. The plasmonic wave is quite similar to radio waves. Or, rather say it, a combination of acoustic waves and electromagnetic waves. Quantum gas is an atom group. In those atom groups, temperature and pressure are extremely low.  The distance of atoms is long. And when an electromagnetic system can pump energy to those atoms. But the thing in quantum gas is that the atoms also make physical movements like soundwaves. It's possible. To create quantum gas using monoatomic ions like ionized noble gas. In those systems, positive (or negative) atoms push each other away.  When the box is filled with quantum gas and som...

What is the difference between TR-3A and TR-3B? And are those planes real?

What is the difference between TR-3A and TR-3B? And are those planes real? Is TR-3B (0) "Black Triangle UFO" or is it only the piece of paper?  The study project, what is used to create advanced ideas for use of the nuclear-powered aircraft. Or is it the study project or black budget aircraft, where lost 2,3 trillion dollars (1)of the stealth bomber were gone. In this text is things, that might seem very difficult to accept, and when we are thinking about things like doubling the object or making it smaller by using huge layers of energy, nothing denies to test those things. But were those tests successful, there is no data about that in public Internet, so we must say that things like doubling the human or aircraft can be tested, but the results can be unknown.  But in the source two is the tale, what seems like impossible, those men, who got Noble Prize put at first time one atom to the box, and hit it with photon one photon in the box and hit it with t...

The interesting coincidence between USS Sea Shadow (1982) and CSS Virginia (1862)

Image I The interesting coincidence between  USS Sea Shadow (1982) and CSS Virginia (1862) Far away from its time is the thing, that you might notice when you see those two images. The upper one (Image I) is portraying the modern naval USS Sea Shadow (IX-529)(1) experimental Stealth ship, which was created by Lockheed-Martin, and the image below (Image II) is portraying the CSS Virginia (2), the ironclad from the Civil War Era. The thing why the hull of the CSS Virginia, what is ironclad from 1862 is that the ammunition of the cannons would not transfer their impact energy to the hull of the ship. And the reason why Sea Shadows hull has this form is that it should point the radar echo away from the hull.  The thing that I must say that CSS Virginia is far ahead its time because that structure is effective against the explosive ammunition, and the slanting armor of tanks like T-34 and Sherman have made them effective. But for some reason, the use of slanting ...
