The world's largest telescope uses "radio quiet" electronics. And the same technology can give a boost to communication and computing. 

Radio quiet electronics are necessary for very highly accurate radio systems. The radio-quiet electronics remove the radio turbulence from the system. And that gives the world's largest radio telescope a new type of accuracy. The world's largest radio telescope is not the only thing that can get a boost from highly accurate radio communication. 

Things like extremely powerful supercomputers that are required to transform binary data into qubits require the ability to control extremely short-term data pulses. Radio-quiet electronics remove radio interference from the microchips. That makes it possible to create nanotechnical microchips that can be used as virtual quantum computers. The interference-free systems also can make it possible to make complicated molecules. 

But radio quiet electronics can also make it impossible to steal information from copper wires and supercomputers. These kinds of systems have many types of use. And one is to offer extremely secure communication by using wires. If the wire uses radio quiet technology, that makes it impossible to eavesdrop on electric noise that travels in that wire. 

The ability to remove the radio interference from the system makes them more accurate. And that makes it possible to use that kind of system in regular communication. The term regular communication means data communication,  used for "normal purposes". Removing radio interference from those systems makes it possible to use lower power and faster pulses than ever before. 

The "radio quiet" technology makes the world's largest telescope very highly accurate. And it can be used for communication and computing. 

"Scientists from the University of Konstanz developed a method using femtosecond light flashes to generate electron pulses with a duration of around five attoseconds. This breakthrough, offering a higher time resolution than light waves, paves the way for observing ultrafast phenomena, such as nuclear reactions".

The fastest manmade radio burst lasts 0.000000000000000005 seconds. 

These kinds of bursts can make communication and computing systems more powerful and faster than ever before. And that is one case where removing the radio interference can make the system more accurate and powerful. The tracking systems cannot find the origin of extremely short radio bursts. 

Because there are no non-controlled oscillations in the microchips. They can control data with higher accuracy. Than ever before. Very fast data bursts can make the information transport more effective, and eavesdropping that kind of system is a very hard thing. In the cryptological process, the key element is to separate and detect the signal that carries information from non-proposal radio signals. 

In peacetime, the network can send so-called empty data packages between data-carrier data packages. That means the attacker can get the data, but there is a lot of work to separate proposal data from the empty data packages. In war, this kind of thing is not safe, because tracking systems can find the transmitters and then the artillery shells will impact the transmitters.

My estimation of Arthur C. Clarke's book "Earthlight" (1955)

"Earthlight"
Arthur C. Clarke
(1955)

"Earthlight" is the novel, what Arthur C. Clarke wrote in 1955, and it is the very futuristic story about the war between the Earth and it's colonies. The book is full of technical things, like the train, what travels on the surface of the moon. This fictional moon train is a quite conventional electric train, what is modified as the space capsule, and it would travel to the station, and then the airlocks would be connected to that system, what allows people to travel on the surface of the Moon. The combat systems that are used in this book, are the probably triangle-shape spacecraft, what have thrust to every side of those vehicles, and that would make those ships, what fictional colony would be used capable to fly like some UFO.


Because the war between colonies, what are known as "Federals" is expected, the Moonbase must be defended, and the defense is the thing, what is prepared almost all of the book. The defense of that base bases the magnetic cannon, what would pump meted iron straight to those targeted spacecraft. The book is actually the story about preparing the war, and how the colonies spies would be searched from the Moonbase. In the last chapter, Clarke wrote that the peace treaty would be made under the control of the Moon, and in this case, I would tell that in the real life, would the Moon be acting in the control of Earth.


There would be many things, what the Moon needs from Earth, and one of them is clothes and the second thing, what Clarke forgot, is that the Moon would be targetted the nuclear weapons from the Earth, or there could be powerful, but an unseen radiological weapon, what could destroy entire Moon in seconds. That fictional weapon could be an actually radiological weapon, and it can be actually misused radio telescope. The thing could be tested in some weapon tests, where are trying to create the protective shield, by using electric arcs.


Those radio telescopes would be synchronized in the same frequency, and then their radiation would be targeted to the heart or center point of the Moon, and this means, that the Moon would be destroyed immediately when the Earth wants. The warming of the center of the Moon with extremely powerful electric arcs could cause the expansion of the nucleus of the Moon, and that would crash entire planet. This is the thing, what this master of science fiction might be thought, when he wrote that novel, that feels so timeless even today.

Interesting theory that maybe we are alone in our galaxy

When we are talking about the theory that maybe we are alone in our galaxy, we must say that maybe we are lucky. Because if there would be other technical civilizations around us,  our faith would be destroyed by the attack of aliens. Here I must say, that if I’m honest, I would win everybody in argumentation when we are talking about SETI-program and alien civilizations. I must choose only the distance, what is so huge, that the radio-impulses from the Earth would not reach that point in our lifetime.


So I can say that maybe there is technical civilization in the distance of thousand light years. And that means the signal from Earth and that point would travel thousand years in one way. If the alien would answer immediately, the signal would travel 2000 years before we would get the answer. This means that none of us would live so long, that the signal would influence our life. That is the problem with searching the extraterrestrial intelligence. Our communication is connected with the speed of light, and that means that the message to Alpha Centauri would travel four years in one direction.


And if we would send the probe to that solar system, would the message alone travel eight years. Of course, the trip to that system would take very long time, and the spacecraft would need extreme independent artificial intelligence to accomplish the mission, what should take thousands of years. And this is Alpha Centauri mission, not any trip to some system like Gliese-581, what is 20 light years from Earth. In here I will write the hypothetical civilization what locates in this solar system.  And then the message would travel 20 years to that solar system, and then aliens must first realize, that there would be the message in their radio telescopes and other systems.


Then they must break the message, and what do you think, do they give the answer? If human race would get the message from outer space, I think that I would take tens of years before we could break the code of that message. And then it would take a long time before we would answer to that message, and first, we must collect the information about those hypothetical aliens. We must know if they are hostile or friendly, and it would take a long time. And we have not contacted with aliens, who live in Gliese system. Or maybe NSA hides that material. Who knows the truth. But we are living in the lonely solar system outside the main milky way formation.


That would save us from the interplanetary conflict. When we are talking about SETI-program, we might get contact to another civilization in tomorrow or maybe it would take 1000 years. And the problem is that we don’t even know, where we must look for that alien.


Maybe in someday, we can create an electromagnetic black hole for communicating with probes, what are send in the orbital of other stars. That wormhole would be smaller than the atom, but using this technology in communication, we must know where to send the signal. The probe is little bit different thing than other civilization because we would know where that thing is, and if we will talk about other civilizations, we would not know where they are.


And there are many stars even in our Galaxy. So if we would want to send the targeted message to all of them, would that take very long time, and in this case, we might say only “Hi we are Human race and living on Earth”. This message would not be very long, but there are 250 billion stars in our Galaxy. And sending the message to all of them would take time. There are 31 556 926 (Google straight answer) seconds in one year. So sending the message to 250 billion stars would take extremely long time. And we would not know any other intelligent civilizations than the human race.
