Ultrasound makes liquids travel through air. But it can also replace propellers in air-cushion vehicles.

Finnish researchers created an ultrasound tube that transports matter through air. The system uses a tube in which ultrasound loudspeakers push matter away from the walls. This allows it to transport sticky liquids through the tube without leaving dirt behind. 

That helps to keep tubes clean. And that is important to avoid blockages. But this kind of ultrasound system can make many other things. The ultrasound system can push water that travels through the tube. This makes it possible to make very thin liquid “beams”. 

Ultrasound systems. Can be used to control plasma. And liquid metals. To. control plasma and liquid metals. Liquid gases. And many other things. Ultrasound can keep hot metal or plasma away from the walls. It can be used. To push jet engine exhaust gas away from the walls of the exhaust tube. 

And that can remove vibrations. Ultrasound systems can also make things like flying cars possible. They can push cars upwards. And if they are connected to the systems. Ultrasound can increase pressure in the cold-gas thruster chambers. The cold gas should expand. That. They can push cars forward. 

Ultrasound systems can also make pressure waves. In. Things like a ramjet engine. They can push air-fuel mixture against the walls of the combustion chamber. That increases pressure and temperature. Another thing is that. In rocket engines, ultrasound systems can press the exhaust gas. And fire away from the engine walls. 

And. That decreases vibration, like in jet engines. In spacecraft, ultrasound can push air away from the spacecraft body. If. The ultrasound spike pushes air away from the hypersonic body. That decreases temperature in that structure. That allows the system to fly lower than usual at hypersonic speeds. 

Hypersonic systems can use ultrasound to move air away from their body. That helps to keep temperature lower. 

Acoustic systems. Can make exotic engine systems possible. 

In ships, ultrasound systems can push water away from the structure. The ultrasound system pushes water backwards. In small boats, the system can push water away from the body.  This thing. Can make things like jet-engine boats more effective. The jet engine pushes the boat forward. Ultrasound. Systems can keep it even airborne. This means an ultrasound system can replace even propellers in air-cushion systems. 

Or makes the front ditch that pulls the ship forward deeper. That makes the ship travel faster. The system pushes water down at the front of the keel. In that case, water in the back pushes the ship into the ditch. That ultrasound is made at the front of the ship. 

In. Some other very exotic propulsion systems. Microwaves or lasers vaporize water. At. The front of the ship. And then water pushes it from the back. In submarines, the system can make a bubble. Or a tunnel at the front of the submarine. And water behind that sub pushes it forward. In submarines, the ultrasound can also push water away from its hull. 

That makes it possible to create submarines that can dive deeper. The ultrasound system. It can. Decrease water pressure against the hull. But. It can also push water away from the submarine. And that can make it possible to run deeper and probably faster. In some visions, the submarine can travel as fast as an airplane. The submarine travels in an acoustic bubble; there, the ultrasound system can push water away. 

And. The submarine can use rocket engines to reach very high speed. The submarine can use its nuclear reactor. To. Separate hydrogen and oxygen by using electrolysis. The problem is that water is much denser than air. So the submarine must create a bubble around it for this system to work. And maybe ultrasound can make that bubble real. 

The ultrasound can make flying cars real. The system uses ultrasound to create pressure that pushes the system upwards. 

Ultrasound systems allow developers to create acoustic levitation systems. The ultrasound can push pallets and even some aerial devices upward. Coherent ultrasound systems make it possible. To create a so-called virtual antigravity system. 

Those ultrasound loudspeakers can create pressure impulses. That can rise. Even heavy objects from the ground. This is one way to make a system. That is so-called virtually silent. The problem with ultrasound levitation is this. The system makes dogs bark.

What if dark energy were once negative?

"Dark energy is a mysterious force believed to drive the accelerating expansion of the universe. Thought to make up roughly 70% of the cosmos, its true nature remains one of the biggest mysteries in modern physics. Credit: Stock" (ScitechDaily, What if Dark Energy Was Once Negative? Scientists Uncover a Surprising New Possibility)

“Negative energy is a concept used in physics to explain the nature of certain fields, including the gravitational field and various quantum field effects.” (Wikipedia, Negative energy). 

A new study suggests that, at one point, all energy was negative. So the energy level was below zero. That means. The event called the Big Bang turned that energy above zero. And that means there is no negative energy in our universe. But what is negative energy? And why is that thing so interesting? We can think of there being two forms of energy. 

Positive. The energy state is above zero. 

Negative: The energy state is below zero. 

Negative energy pulls positive energy to it. In. Some models. The negative energy is like gravity. That means it is energy. That pulls positive or “visible” energy to it. Some other models suggest that. The cold points are closest to the thing. That. We know as negative energy. 

One model of that negative energy is the case. There. The energy level decreases below the energy minimum. This means the pothole's energy level is below zero, so it starts to pack energy around it. So in that model, negative energy could form the Big Bang. Before the universe was born, or before matter and time separated. There was some. Kind. Of quantum field. Then. There was something. That caused the situation. That quantum field lost energy. in. One of its spots. That could happen when a lower-energy field came too close to that primary field. That field transported energy from one spot. And the field around that structure tries to fill that hole. 

Or energy traveled from a higher-energy field to a lower-energy field. That formed a hole in the field that received energy. Then the entire energy field travels in that hole. And that raised the energy level in the middle of that energy pothole. This means that negative energy packed positive energy around it. Or. Positive and negative energy behave like matter and antimatter. That means. Negative and positive energy pull each other together. They form extremely high energy waves.

Or it raised the energy level so high that it turned positive. This means dark energy caused the Big Bang by packing energy around it. This type of energy is very hard to make. The three-kelvin cosmic background. It is three degrees higher. Than. Absolute zero (-273.15 °C). Reached in the laboratory was. If the object has this temperature and we transport it into the universe. That means. That. This object packs energy itself. 

If. That object is homogeneous enough. Its entropy is low enough. That energy can travel in that object. And then jump back. If. The object is large enough. It packs energy into its center. The idea is that. When the ball is very cold, it binds energy from its environment. It takes energy into its shell. Energy travels into the center of the ball because the center is colder than the shell. Normally, that means nothing. But if the object is a perfect ball. Energy. Travels to the ball at very high speed. The reason for that is. 

The extremely cold core pulls energy into it. In the core, the energy impacts. And jumps back. This will not happen in asymmetrical objects. This can happen only if the object is a ball. The energy. Must impact the ball symmetrically. That denies it from breaking out. The cold core pulls energy into it. And. That continues until energy breaks out. That can rip the ball into pieces. How strong can that effect be? That depends on the speed. On. How energy travels to the object. 

In the young universe, energy levels were higher. This means that the energy minimum was higher. Materia was denser. And stars were brighter. In that time, the negative energy was already gone. That means negative energy can still exist. But it's outside the universe. 

If. Somebody could create that negative energy. That makes it possible. To create things like the Tipler Time machine. That rapidly spinning cylinder. It creates time dilation in it. By. Using spinning motion. The problem is that Centripetal force rips that structure. 

Into pieces. The answer to that problem is negative energy. Negative energy pulls the structure into one form. Negative energy can make it possible. To make things like faster-than-light travel. In those models, dark energy pulls energy against the craft. That denies. Quantum fields jump out of the craft. And that aims energy flow to the craft. 

Negative energy pulls quantum fields against the cylinder shell. And it acts a little bit like magnetism or gravity. And in some models. It is the second gravity. But if that thin still exists. It’s hard to separate from gravity. The problem is that. Nobody created that negative energy.

The world's first superconducting quantum heat engine is real.

“Artistic impression of a superconducting quantum heat engine. Credit: Heikka Valja / Aalto University”  (ScitechDaily, World’s First Superconducting Quantum Heat Engine Could Transform Quantum Computing) 

Finnish researchers have created the first quantum heat engine. “Researchers at Aalto University have built the first cyclic quantum heat engine inside a superconducting circuit. The device uses a qubit, the basic unit of quantum information, as its working substance and repeatedly drives it through heating, cooling, and energy conversion.” (ScitechDaily, World’s First Superconducting Quantum Heat Engine Could Transform Quantum Computing) 

“Quantum heat engines have previously been demonstrated with systems including trapped ions, atomic gases, nuclear spins, and defects in diamonds. Superconducting circuits are especially important because they are already among the leading platforms for quantum computing, communication, and sensing. Until now, however, no experiment had completed a cyclic quantum heat engine using this technology.” (ScitechDaily, World’s First Superconducting Quantum Heat Engine Could Transform Quantum Computing) 

“The immediate significance is not the amount of work generated, which is extraordinarily small. Instead, the experiment shows that heat can be deliberately controlled and converted inside the same type of circuitry used to build quantum processors.”(ScitechDaily, World’s First Superconducting Quantum Heat Engine Could Transform Quantum Computing) 

Quantum engines are the miniaturized versions of nanotechnology. If those systems. They can put particle spin very fast. When particles spin in the cage. It pulls energy through that structure. That causes a quantum glow in that cage. Basically, a quantum engine; it’s similar to other engines. e It can use the magnetic field and IR radiation combination. To make transform radiation into motion. Those systems. They just transform wave movement. Or electromagnetism. Into kinetic energy. So, when the core in a quantum engine spins. That core binds energy into it. When its speed accelerates. When it slows. It delivers energy. 

“That capability may become valuable as quantum computers grow. Today’s superconducting machines depend on large numbers of microwave cables running between room-temperature electronics and processors kept at temperatures only a fraction of a degree above absolute zero. Each cable adds cost, occupies space, and can carry unwanted heat or noise into the system.” (ScitechDaily, World’s First Superconducting Quantum Heat Engine Could Transform Quantum Computing) 

“The researchers are now working toward a fully autonomous version of the engine. One possible application would be reading the state of a qubit without sending a microwave signal from the cold processor to room temperature. Placing more control functions directly inside the cryogenic circuit could reduce the amount of external wiring required.” (ScitechDaily, World’s First Superconducting Quantum Heat Engine Could Transform Quantum Computing) 

The quantum engine that transforms infrared radiation into motion is a fascinating tool. 

This. Kind of system. It can transform all radiation types. Into another by using motion. The radiation. Like radio waves. Hits the quantum engine. It starts to move. And then. It transforms that movement into electricity. Then that electricity. It can be used. As an example, an X-ray system.

Quantum system. That transforms kinetic energy into motion. That thing can be the new tool for micrometeor and armour technology. If the system can transfer impact energy into rotating movement. That can turn a surface extremely hard. In stealth technology. That ability to transfer electromagnetic radiation into movement. Makes it possible to pull standing waves out from space between atoms. Those systems. 

This kind of system. They can feed energy to quantum computers. The system. That can transform radiation into motion. This can bring interesting ideas for energy sources. To the journeys to the edge of the solar system. The quantum engine that can turn minimal energy into motion is the thing. That could replace at least some of the RTG (Radio Thermal Generators). Used in long-distance space journeys. Or those systems. They can at least make the RTG power sources more effective. By benefiting from the temperature that those isotope generators deliver. 

Nano- and quantum technology that transforms heat into motion. That is the system. That can help to create more sustainable materials. That stand the heat. The idea is that those quantum systems. They can transfer heat energy from the shell of the spacecraft or airplane into a moving part. This turns infrared radiation into movement. And then that nano-. Or quantum generator. It can transform the heat into UV light. 

This kind of transformation is quite easy to make. The nanotechnical generator. It simply transforms heat energy into electricity. Then that electricity. It can be transferred to UV light. This kind of system. It can transform almost any wavelength into another. When things like radio waves hit this kind of system. That system can transform radio waves into X-rays through motion. This kind of system. They can be the next-generation tools. For new stealth  technology.

A couple of thoughts about alien intelligence.

Where are aliens? That is a very good question. There are many theories about the lack of extraterrestrial intelligence ETI contact. Search for Extraterrestrial Intelligence. The SETI program continues its search. And as I have many times. Written before. We are alone until we have contact. And there is a possibility. That we will see an intelligent alien civilization even tomorrow. Or maybe. We will find that thing from 1000 years in the distant future. The alien intelligence is a mystery until we find it. 

There are many theories why aliens don’t contact us. Maybe they don’t just want to talk with us. There is a possibility that an alien civilization is a very long distance away. They might have other problems than our messages. But when we think about an alien civilization. That civilization might know as much about us as we know about it. So, if aliens have radio telescopes. They are intelligent. Or they can make the radio systems. 

That information is not very much. And if we fear the alien, the same way. The alien is afraid of us. They don’t know anything more about us. Than. We know about them. SETI is not a movie that portrays us as good. The aliens don’t know what kind of creatures we are. 

The alien culture might not be similar to ours. That means. They might think differently from us. If we think of an alien civilization, it might be something. Like the Kardashev II stage. That means it can travel in its solar system. And maybe nearby stars. That civilization could be more advanced than we are. But. Its technology is not advanced enough for interstellar routine operations. 

The alien civilization must also be afraid of the signal transmission. What they receive is not a trap. There is always a possibility that the transmission is meant to uncover. Intelligent alien locations for hostile actions. There is always a possibility. That some other alien civilization wants to whip off. Their competitors. When we search for extraterrestrial civilizations. We must remember that those civilizations are always. Different. Than we are. The fact is that. We don’t know any alien civilizations. 

The next part is a philosophical thought. About the UFO. 

And even if somewhere in highly secretive military areas. There is. Some kind of captured extraterrestrial UFO. Or even if somebody captured single aliens. That doesn’t mean that maybe three or five aliens are the entire civilization. And maybe those creatures don’t even know the planet where they left. In that hypothesis, the “visitor” is the genetically engineered creature. Specially made for interstellar missions. 

It’s possible that a hypothetical alien creates those biorobot intelligence units inside their craft. Those creatures might be stored in the chambers as fetuses or as some kind of spores. When the craft travels near the promising planets. The craft, or its AI. Wakes those creatures alive. 

The “traveler” might not be anything like the creature that created it. This is one thing that we must understand. Those aliens might use things like biorobots. Microchip-controlled bodies. Those bodies might not have any memories. And. They could use the implanted microchips for communication. With some kind of relay station. Those systems can transmit data from the targeted civilizations. 

And finally. It’s always possible that aliens just don’t want to disturb us. They might just observe. If they know our existence. Or maybe aliens and we don’t detect each other’s communication. Theoretically, it is possible that an alien civilization is so far away. That our signals don’t reach them. And maybe the signals that they might send don’t reach us. Or maybe they are so weak that we cannot detect them. But until the alien calls, the search continues.

The Muon G-2. And the missing fundamental interaction.

“A muon is a fundamental particle similar to an electron. But. About 200 times heavier and much less stable. It exists only briefly before decaying into lighter particles, making it a useful probe for studying subtle effects in particle physics. Credit: Shutterstock” (ScitechDaily, Scientists Were Wrong About This Strange “Rule-Breaking” Particle)

The question about the centrifugal force is this: could some form of centrifugal force be the missing fifth force? This means that there could be a quantum version of the centripetal force. The force that makes an electron send a photon outside its trajectory. That effect causes a lower energy state for the electron’s outer side. And that pulls the electron away from the atom’s nucleus. 

The Muon G-2 test didn’t bring evidence of the fifth force. However, it could provide a hint for the centrifugal force, or its quantum model. When a muon orbits the center of the cyclotron, it sends a photon. Just like electrons make. This phenomenon forms a small quantum of low pressure at the point where the photon, or wave that turns into a photon, leaves. That low pressure has an effect on the trajectory of the muon. The muon is a short-lived particle. That means the radiation. That it sends is stronger than in the case of an electron. 

And that pulls muon away. So there could be some unpredictable energy field that caused the unexpected effect on the muon’s trajectory. The muon itself is a fermion. similar to an electron, but much more massive. We can see the results of the Muon G-2 anomalies, and we can make two conclusions. The anomaly was in the limit. Or it was on the edge of the unpredictable and predicted. This means that those results are “almost, but not certainly”. This means that today reseachers have not found the fifth force. 

But. Theories. Like the Grand Unified Theory (GUT) and the Theory of Everything (TOE). Try to explain that the four fundamental interactions are a form of one force. At the theoretical level, we can say that by using the electroweak interaction. The energy or photons should travel from the gluon to the Z boson and then to the W boson, which transports energy into the electron. Electron sends a photon. Out from the atom. And that thing can cause the electromagnetic low pressure near electrons. That explains the gravity. 

There is a possibility that gluons. Could. Have a spin motion. Which means they can send photons. There is a small part in an atom. That researchers don’t know. This makes it impossible to fit. Quantum gravitation and Newtonian dynamics together. This causes one of the most interesting questions. Could centrifugal force be the thing that we could call the fifth force? 

Centripetal force is the virtual force. That forms the situation. The smaller object orbits the larger one. The recessive object stores kinetic energy in it. And that energy keeps the object in its orbit. 

The fact is. That seems very far-fetched. But then. We can think that when a less massive object orbits the gravitational center, the secondary, or the less massive object, collects gravitational waves. Into the form of a deep ditch just behind the secondary object. That shadow pulls the object away from the gravitational center. 

Another form. Could be.That. The quantum fields around the gravitational centers hit together. Both of those objects have their own gravitational pothole. And that packs quantum fields against both of them. That causes a situation. Where those fields push each other away. In this model, the orbiting gravitational centers form the energy hill around the gravity pothole. That hill also denies. The object. To fall to the gravity center. Those things can seem nonsensical. 

But the problem is that they all form centrifugal force. This means that the uniting gravity waves could cause the other object to travel away from the gravity center. This requires a very deep gravity ditch at the opposite side of the recessive object. 

But this means. That gravity might not be one single interaction. We can think. That. Gravitation is a wave movement that is between the second and third dimensions. This low-energy radiation forms the ditch that we call gravitational waves. That happens when the low-energy radiation pulls energy out. From the higher energy radiation. This explains why gravitational waves. Turn weaker. When the distance to the gravitational center grows.

Positronium as a tool that can revolutionize the world

“Quantum physics revealed that matter can behave like waves, a concept famously demonstrated through interference experiments but never directly observed in certain exotic systems. Now, researchers have extended this phenomenon to positronium—a short-lived electron–positron pair—showing it produces clear diffraction patterns and behaves as a unified quantum object. Credit: SciTechDaily.com” (ScitechDaily, Researchers Capture Quantum Interference in One of Nature’s Rarest Atoms)

“Scientists have made the first experimental observation of matter wave diffraction in a short-lived electron-positron atom.”(ScitechDaily, Researchers Capture Quantum Interference in One of Nature’s Rarest Atoms) And this can revolutionize communication. And things like laser technology. 

Positronium is one of the rarest things in the universe. Somebody says that it’s an atom. Somebody classifies it as a quasiparticle. The positronium is the system. The positron and electron orbit each other. One of the things. That could stabilize. The electron and positron system. It is an exciton-type energy hole. 

In that model. The system puts. An electron and a positron orbit the energy hole. The problem is how to create a neutral exciton. The exciton is a positive hole in the energy field. And the electron orbits that hole. But in the case of positronium. The system should neutralize the repulsive effect between the positive hole and the positron. The stabilization of the mass center stabilizes this structure. The extremely thin laser beam. It could make this stable energy hole a reality. 

Positronium may someday hold the key to creating a small and effective antimatter annihilation system. Positron and electron are mirror particles. When those particles collide, it causes annihilation. This means that both particles turn into energy. The controlled annihilation. It can be a tool that creates high-energy radiation. 

"An electron and positron orbiting around their common centre of mass. An s state has zero angular momentum, so orbiting around each other would mean going straight at each other until the pair of particles is either scattered or annihilated, whichever occurs first. This is a bound quantum state known as positronium." (Wikipedia, Positronium)

“Frenkel exciton, bound electron-hole pair where the hole is localized at a position in the crystal represented by black dots” (Wikipedia, Exciton)

The system called positron emission tomography (PET) uses this radiation. For making images of the tissues. The technology. Where those positrons are stored in the form of positronium. Can. Make it possible to create small, portable PET scanners. The positron cloud can also make it possible to create an antimatter weapon. The positrons are hovering in a magnetized vacuum bottle. The magnetic field keeps those positrons away from the walls of the bottle. When the system must be detonated. It allows positrons to interact with their environment. 

The positronium. Makes it possible to create gamma-ray lasers. The positronium chains are around the tube. Then, at the bottom of the tube, the electron-positron annihilation happens. The system also annihilates positronium chains. Around that energy beam. This reaction can be used to create a coherent X-ray impulse. 

The thing that makes positronium so reactive. Makes it a perfect tool for quantum cryptology. The positronium can create DNA-style chains. And the system can store information. In those chains. If the wrong person tries to open the message transporter, it causes annihilation. 

The system can store data. In the positronium, and then make the quantum entanglement between two positronium particles. After that. The system destroys those particles by allowing electrons to interact with positrons. This means that the same technology has multiple purposes. The positronium USB can also act as an antimatter bomb.

When planets are in the wrong order. (LHS 1903)

"LHS 1903 is a small red M-dwarf star that is cooler and shines less brightly than our Sun. Scientists used telescopes in space and on Earth to discover four planets orbiting LHS 1903. With those telescopes, they classified the three closest planets to the star as the innermost being rocky, and the two that follow it gas giants. Credit: ESA" (ScitechDaily, This Alien Solar System Doesn’t Follow the Rules – and Scientists Are Intrigued)

“LHS 1903 is a red dwarf star located about 116 light-years from Earth in the constellation Lynx, near 21 Lyncis. It is thought to be a member of the Milky Way's thick disk.” (Wikipedia, LHS 1903)

“It hosts four known exoplanets. Its planetary system has been described as "inside-out", as instead of the usual pattern where gas planets tend to form further out, its planets are arranged in a configuration where the innermost and outermost planets are rocky, while the middle planets are gas dwarfs.”(Wikipedia, LHS 1903)

“In the late 20th century, scientists often described planetary formation using our solar system as a template. In that view, small rocky planets form close to the Sun, while gas and ice giants form farther away. However, the discovery of more than 6,128 exoplanets across 4,560 systems, along with unusual types such as hot Jupiters and planets orbiting pulsars, suggests that our solar system may not be typical.” (ScitechDaily, This Alien Solar System Doesn’t Follow the Rules – and Scientists Are Intrigued)

“Hot Jupiters (sometimes called hot Saturns) are a class of gas giant exoplanets that are inferred to be physically similar to Jupiter (i.e., Jupiter analogues). But they have very short orbital periods (P < 10 days). The close proximity to their stars and high surface-atmosphere temperatures resulted in their informal name "hot Jupiters.” (Wikipedia, Hot Jupiter) 

Could planets change their place? This is a good question. The LHS 1903 is the red dwarf. The M-type star is far less bright than our Sun. The mass of that star is far lower than that of our Sun. That star has a planetary system of four known planets. The planetary system of LHS 1903. Fits in the Mercury trajectory. If we compare it with our solar system. 

The planet’s order in this system is interesting. The inmost and outmost planets from the star (LHS 1903, B and E) are rocky planets. And the center planets (LHS 1903 C and D) are mini Neptunes. Those mini Neptunes' mass is about six times that of Earth. And their diameter is about twice Earth’s diameter. 

“The location of the LHS 1903 system in the constellation Lynx. Credit: Stellarium.” (ScitechDaily, This Alien Solar System Doesn’t Follow the Rules – and Scientists Are Intrigued)

The LHS 1903 planetary system (Wikipedia, LHS 1903) 

Also, those two rocky planets have a very large mass. The fact is that. When we see the table of that solar system. We see. The outermost planet E is almost as massive as planet D, and it's also more massive than planet C. So, could that mean that the LHS 1903 is trapped some of those planets around it? If we think of the possibility. The planets changed their places. That requires that something. 

More massive than LHS 1903, it formed. Some kind of mass center. And then turned the entire solar system around. Could some. A very small thing, like a small black hole. Travel between those planets? This kind of thing could spin. The planetary system around that mass center. 

 In planet formation models, the rocky planets are nearest. The reason for that is the solar wind. That blows the light elements away from around the planet. But there is one thing that makes LHS 1903 interesting. The rocky planet is massive. That means it could also lose its gas layers. The cosmic event, like some kind of particle beam, can strip the light elements from around that planet. 

The massive “hot Jupiters” can be very close to their star. If there is a solar system. The innermost planet is a “hot Jupiter”. And others are lighter rocky planets. That can form in a situation where the star “robs” other planets than the “hot Jupiter” from other solar systems. In cases of “hot Jupiters,” the planet’s massive gravity can resist the starwind.
