Pluto might have hot past

 

Pluto
Pluto might have hot past

Somebody believes that there is still liquid water in Pluto and the tidal force of Charon would keep that water liquid. The reason for that is the white area on the downside of the planet. Another explanation for that area is that it is forming when the atmosphere of Pluto is turning to snow. But the question is, why that white snow is not everywhere on that planet? 

There seems not to be dust on it, which means that is quite a young geological area. But truth is that the extreme cold on that planet makes every chemical and geological process very slow. And liquid water doesn't mean that there are the lifeforms. The small size of Pluto causes that there should not be internal volcanic actions on that planet, and if there are some liquids, that thing keeps in liquid form, because of the tidal force of moons of that small world. 

But the thing is that Pluto has not always been where it is now. That dwarf planet has been somewhere else, and there are theories that it is lost moon of the Neptune or Uranus, and that thing makes this dwarf planet interesting. There is something, that has pulled Pluto to its trajectory. But of course, Pluto can be born near the sun. 

Planets like Uranus and Neptune have changed their places in our solar system. And there is a small possibility, that there has been some kind of lifeforms on the surface of Pluto. If there has been an active life, those organisms will be frozen to extremely low temperatures. And there is a possibility, that the genomes of those organisms can be read by using modern technology. But truth is that Pluto is too small to maintain a stable atmosphere. The solar wind would blow the gas away from that planet if it is in the habitable zone. But there is a possibility, that under the ice core of moons like Europa moon of the Jupiter or Triton moon of Neptune could be primitive lifeforms. 

Triton is a massive moon, where there are so-called "black geysers", which means that there is a possibility to be ocean under the ice, and there could be lifeforms, which can get their energy from the hot water. The high-temperature of the water near the solid surface of those ice-moons is the result of the tidal forces that are causing volcanic eruptions and keep the oceans liquid. If there are life forms on those moons, they might be similar to organisms, which are living near hydrothermal vents called "black (or white) smokers" of the ocean floor. 








Neptune
The anatomy of gas planets 

The gravity of Uranus and Neptune is quite huge. But the thing is that those planets are mostly gas. There is no solid surface until on the nucleus of the plane. So all of the mass of those planets forms the gravity field. That mass is forming by the atmosphere and nucleus. The gas planets have a liquid layer near their nucleus and the massive pressure turns the liquid gas to the liquid. 

The solid nucleus of gas planets is quite small. The gravity on the surface of the nucleus is quite small if we compare it with the gravity at the top of the cloud layer. In the last point, the entire gravity of gas and the nucleus of the planet will pull the object downward. 

There has been introduced a thing that the gravity on the surface of Uranus would be similar to Earth. But the problem is what is the point of the atmosphere, where that metering has been made. That kind of point is found also in the atmosphere of the Sun. But the thing is that every gas planet has the nucleus, which is solid. And if that metering or calculation has been made on the surface of the solid nucleus, the gravity would be quite light. 

The same way the gravity is zero in the middle of every single planet. The thing that forms the gravity field of the planet is the entirety of the atmosphere and solid nucleus. So the entire mass of gas planet Uranus is 14,536 Earth-mass, but the problem to calculate that thing is that Uranus is the gas planet, which has no solid surface until it's the nucleus. The mass of the Neptune is 17.147 Earths, so this planet is a little bit larger than Uranus.

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 ...
