The galactic civilizations




Futuristic alien city

The galactic civilizations or Kardashev scale 3 civilizations are the speculations of the models of advancing intelligent lifeforms. And I certainly hope that humans would someday in the future after thousands of years reach this scale. But the fact is that before species would turn to galactic or even interstellar scale civilization it must first conquer its solar system. 

That is the first step for conquer the entire universe. But for taking the first step in the Kardashev scale the species must have the motive to make that kind of step. Making the bases to other planets is not cheap. And that's why there must be some kind of motive for that kind of investment. 

One of the reasons why the civilization would want to establish bases and then cities to other planets could be the lack of raw materials and then overpopulation. The thing is that making the cities for ordinary people who have no training for space operations is a little bit different thing than making the base for maybe 20-50 highly-trained specialists. 

If the species want to solve the problems of overpopulation by dumping its people into space. That requires extreme high-class construction skills and also huge investments in technology.

Even the cities with a population of millions are not solving the problems of planetary-scale overpopulation. But creating large-scale bases for the other planets can cause the chain reaction that makes civilization take the next step in the Kardashev scale and conquer the other solar system. 

There can be two types of population in the civilization of tomorrow. The spaceship crew that ever land to planets. 

Those creatures might awaken during the journey. And the crew that is landing on planets. The last ones might travel in deep hypothermia or frozen in zero degrees kelvin. 

The scale of the universe is enormous. And that means if there is no faster-than-light technology the journeys between solar systems take a very long time. So the advantage of that kind of civilization can be that there are two types of citizens. 

The population that lives in the spacecraft all their life. And the population that lives on planets. Maybe the last ones are traveling between solar systems in deep hypothermia. And during those journeys, the generations of the ship crew are chancing. 

The thing is that there are lots of resources in the solar systems. But resources are not endless. And sooner or later all asteroids are used in artificial worlds and cities that are under giant domes. So the civilization would start to move to another solar system. In that case, there could be other civilizations that might resist those conquerors. 

And that can begin the star wars. The war between civilizations is not a very nice thing. The weapons that those civilizations use might be antimatter clouds and mega-lasers that can terminate entire stars. In some scenarios, the Kardashev II-scale civilization would be the biggest threat to other civilizations. 

That kind of civilization might trust its technology and skills so much that it can try to sweep other civilizations away from it. The thing is that if two civilizations are on the same technical level. That thing might force them to discuss things. And maybe death stars and antimatter cannons are helping to make bridges between civilizations. But the future might show the future of the human race? Is it bright or is it dark? The choice is us. Or our descendants. And we cannot see the future. We can just try to predict it.

Virgin Galactic space shuttle


Space tourism is opening the road to solar system-scale operations and stable bases at other planets. 

Space tourism is making it possible to create technology that allows non-trained persons to fly at orbiter. Those kinds of systems are needed in the most dangerous moments of space trips. The lifting-off and return are the most dangerous moments in space travel. 

Space tourism can be the key to conquering the entire solar system. Today the space tourist's journeys take quite a short time. The future can be different. And some companies are creating plans for space hotels where people could stay longer time. 

That thing can cause some kind of changes in the proteins of neurons. The article below this part of the text highlights that there are no structural damages in brains. 

The thing is that the astronauts are staying in ISS for about 4-5 months. And the space tourist spends there about 1-2 hours. So the brain damages might be not so large as they could.

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 ...
