One thing about aliens and Earth-type planets

One thing about aliens and Earth-type planets

The problem by using statistics for calculating the number of civilizations from the universe is that we know officially one single technically advanced and intelligent civilization. And that civilization is created by Homo Sapiens. The thing is that if we are thinking more carefully about the civilization in the Kardashev scale and our race, we must remember that we are maybe at the level 0,7 or 0,8 in that scale, and that means we are proto civilization. And here we are continuing to think about the form of aliens.

When we are thinking about the form of the aliens, we must remember that there is one thing, what we must realize. The Earth-size planet that is in the habitable zone doesn't mean that the intelligence starts to dominate in some species. And the thing that caused that the form of the intelligence replaced a large number of descendants on the Earth was the meteorite, which destroyed dinosaurs. But the things like ice-ages transformed the culture of humans, that it started to favor technical solutions like houses and weapons.

But the thing is that we know one Earth-size planet, what is a straight copy of Earth, and the distance to that planet is about 3000 light-years, so radio waves are traveling to that planet 3000 years. And then the radio signals must travel back to Earth 3000 years. So if there is some kind of intelligent civilizations we would get an answer that takes 6000 years, and in this hypothesis, aliens would answer immediately, and that thing is far away from the realistic models. They maybe think the while, can they answer, and would the answer serve their benefit.

So what means that the distance to some planet is 3000 light-years? That means that we see that planet, what it looked like 3000 years ago. And what the earth looked like 3000 years ago? If we will send the data transmission to that planet, we would have a good time to wait for an answer, and if there are intelligent aliens, they have time to advance. So this is one thing, what we must remember.

But when we are looking at the alien civilization, we must remember one thing. Those civilizations and species are formed by evolution, what is happened on another planet. So they are creatures, what is fully adapted to their home planet. And at this point, we should stop to think that the human race is the center of the universe. The place that might seem quite uncomfortable for us is a paradise for the creatures, what are formed in that place.

At this point, we must remember that even Earth is not a paradise for humans. In most of the areas of the Earth, we need some kind of clothes to protect us against cold weather. Or can we live at Tundra without clothes? There might be very cold in the winter. So that kind of area requires clothes. When we want to be honest about the aliens and alien civilizations, there are billions of planets, and billions of stars. But we know only one intelligent species.

Drake Equation

Fermi paradox.

There is a formula, that is used to calculate the probability to find another civilization. That formula is called the "Fermi paradox" causing the thing, which is known as "Drake equation". When an astronomer named Frank Drake introduced his famous formula for calculating possibilities for finding intelligent civilizations, there was only one confirmed solar system.

That solar system has only one Earth-size planet, where was the intelligent life form and that planet was Earth, and the intelligent species is Homo Sapiens. This thing makes this thing the paradox. If we know only one solar system, where is one planet in the habitable zone, and we use that value in the formula.

If we that formula used to calculate the probability to find the intelligent and technically advanced civilization means that Every planet, what orbits the similar star at habitable zone would have the intelligent and technologically advanced aliens. But can we make contact with those aliens? The thing is that those aliens need to build radio telescopes and follow the hydrogen alpha-emission for getting messages from the human race.

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 ...
