The new nanomaterials are stronger and more durable than ever before.

Nanotechnology opens the door to new lightweight materials. Those materials are lightweight and stronger than anything before. Some of the latest materials are based on ring-shaped spring structures. That material includes two entangled material lines. 

The material acts like spring beds. When impact comes it pushes the "8" shaped structures sideways. That transfers the energy to the molecules around it. The two-material structures make it possible. That impact energy cannot affect materials. As an entirety. The material becomes more durable when the number of horizontal material layers with different molecular structures rises. 

The image above this text shows how the structure can flex when something presses it. When this structure faces pressure the molecule chains that base is in carbon will flex and that ability shares the impact energy with other molecules. If we think that the material forms lattice layers that thing means that material shares energy horizontally. The important thing is that there should not be reflection from other molecules. That denies the form of the standing waves. 

Material can stand high energy levels if it can conduct that energy somewhere. Those lightweight materials have many uses from satellites to armored vehicles and wearable body armor.

The new thing that nanotechnology allows is the ultimate heat resistance. The traditional way to protect the layer against heat is to conduct it away. There can be pillars in the airflow that conduct heat from the layer to that airflow. But this thing doesn't remove the horizontal heat effect. This is why heat destroys molecules. 

When heat impacts a snowflake that structure melts because the snowflake cannot put that energy anywhere. That forms standing waves that destroy the structure. One of the answers is to make the material that edge is colder or at a lower energy level than the middle of it. That conducts energy out from the center.  When energy travels in one direction it will not make those standing waves. 

The magnets can be the solution for the materials that turn stronger when they face pressure. In still theoretica nanomaterials there is some kind of magnetic structure-nanocrystal compounds. When something presses those nano-crystals they form a piezo-electric phenomenon that makes the magnetic fields in magnetic structures stronger. When that phenomenon is connected to alter magnetism the new form of magnetism that means the materials is antimagnetic from outside. The magnetic structures are inside that material. 

The Quanta magazine tells about an interesting phenomenon. "Researchers cooked up a striking exception. In a string of results over the past few years, researchers have shown that an idealized substance resembling two intermingled magnets can — in theory — maintain an orderly pattern no matter how hot it gets. The discovery might influence cosmology or affect the quest to bring quantum phenomena to room temperature." (Quanta, Heat Destroys All Order. Except for in This One Special Case.)

There is a theoretical possibility that the intermingled magnets can keep their form without depending on the temperature. That phenomenon is one of the newest and most interesting things in material sciences. The idea is that the magnetic particles can bind to each other without decreasing temperature. In ideal cases, there are magnetic particles whose magnetic force rises when temperature rises. That makes the material stronger when its temperature rises.

The new material absorbs all electromagnetic waves.


"Researchers have created an ultra-thin film that can absorb almost all electromagnetic waves across several frequency bands, significantly boosting the performance of wireless communication devices. (Artist’s concept.) Credit: SciTechDaily.com" (ScitechDaily, Breakthrough Material Perfectly Absorbs All Electromagnetic Waves)

"The team, led by Dr. Byeongjin Park and Dr. Sang Bok Lee from the Composites & Convergence Materials Research Division at  Korea Institute of Materials Science, KIMS, synthesized a magnetic material by altering the crystal structure of ferrite, enabling it to selectively absorb desired frequencies. They produced an ultra-thin polymer composite film and incorporated conductive patterns on the film’s back side to control the propagation of electromagnetic waves. (ScitechDaily, Breakthrough Material Perfectly Absorbs All Electromagnetic Waves)

By adjusting the shape of the conductive pattern, electromagnetic wave reflection at specific frequencies can be dramatically reduced. A carbon nanotube thin film with high shielding properties was also applied to the back to further enhance the material’s electromagnetic wave shielding capabilities." (ScitechDaily, Breakthrough Material Perfectly Absorbs All Electromagnetic Waves)

The new material absorbs all electromagnetic waves. That makes this material a new and powerful tool. To protect quantum computers and stealth aircraft. The material that absorbs all electromagnetic waves can protect things like quantum entanglements and nanotechnical processors against outcoming energy. And that can eliminate outcoming energy and interference. 

That ability can make this new material more ultimate than we even imagine. If the material absorbs things like X- and gamma rays it can make breakthroughs in nuclear technology. The material can protect people against nuclear radiation and thermal effects. It can make it possible to create new, lightweight space suits and protect people against the heat of the sun. That material can act as an insulator between engines and workers. 

If we have material that absorbs all electromagnetic radiation that means we have material that turns people and systems like vehicles and aircraft into the shadows. The idea in absorption is that the material will not reflect any radiation back from it. That means material stores electromagnetic energy into it. And then. The next step is to conduct energy out of that material. 


"Above: B-21 "Raider" is the planned successor to B-2 "Spirit" famous stealth bomber. The stealth technology base is in minimized reflection. That denies radars getting radar echo. If there is no reflection. The aircraft turns into a shadow. 


The problem with materials that absorb electromagnetic radiation is this: where can it put that energy? 


If the material can collect all electromagnetic radiation into one reflecting wavelength and turn the reflection into, for example, gamma rays. The other version is to store that energy in a material. Then the system conducts energy out from the material. 

The main problem with radiation-absorbing materials is where they can put the energy. That they store. There are a couple of things that can answer the problem. The requirement is that the material turns electromagnetic waves into heat or IR radiation. That thing is easy to transport out from the material.

The system that turns the energy into kinetic energy can pull energy into spinning nano-or quantum structures. The other versions are systems that turn heat energy into electricity. Those systems can also transport energy out from the hypersonic aircraft structures. And those systems can also transport thermal energy out from the shells of fusion reactors and new nuclear fission reactors. 

If material turns electromagnetic radiation into thermal energy it's quite easy to make the system there is a colder place in the middle of the airplane. Then. That thing conducts thermal energy in the desired direction. And if all energy can be conducted that way. The system makes the material visible. Or makes it look like a shadow. 

In some versions of the non-linear graphene structure with the small-size nanoturbines. The idea is that the material takes energy and stores it in its structure. Those nano turbines transform that energy into kinetic energy that can conduct electromagnetic energy out from the material. The spinning nanostructures are one way to conduct energy. Out from the layer. 

The other version is to use systems that turn thermal energy into electricity. That system makes it possible to conduct heat away from the surfaces of the hypersonic aircraft. And. It can also be used to conduct thermal energy out from other extremely hot places like the shells of fusion reactors.

Three red galaxies at the edge of the universe.


"These three "red monster" galaxies, found just 1 billion years after the hot Big Bang, are dusty, massive objects with more than 100 billion solar masses worth of stars inside. Unlike more modern massive galaxies, where no more than 20% of their gas has been converted into stars, these galaxies are two-to-three times more efficient, raising questions about how they formed and grew up to exhibit these apparent properties." (BigThink, What do JWST’s “red monster” galaxies mean for cosmology?)


The JWST telescope found three red galaxies. Those galaxies existed in the universe that was only one billion years old. And that can mean that those three galaxies cause the need to adjust the cosmological models. It's possible that Einstein's theories are not suitable for the young universe. The red color means that the galaxies travel straight away from us. And those galaxies might be on the opposite side of us. 

The big question is this. How those three galaxies could be so big? In some ideas, there could be some cosmic void around the supermassive black holes. That cosmic void could boost the black hole's pulling effect. The cosmic void around black holes can make material fall near black holes faster than just gravity allows.  

The cosmic void has a larger surface area than a black hole, and material should also fall into cosmic voids. And maybe that is the thing that made those galaxies grow faster than expected. In some models, the cosmic voids form the supermassive black holes. The cosmic void makes material fall into it. And in the middle of that thing forms the material center. 

Those galaxies have active black holes. And maybe there are stars. The heavy element formation needs only the impact waves or shockwaves that cause fusion. Things like supermassive black hole's relativistic jets can form heavier elements. As well as stars from them in fusion reaction. When elements impact each other and form new heavier elements we can always call that event fusion. 

In some models the Milky Way, our galaxy is in the middle of cosmic void. The size of that void would be about 2 billion light years. The thing that this void tells is this. There was some force like a very strong eruption in our supermassive black hole, Sgr A* that blew gas and dust away from around our Galaxy. 

That can tell that the Milky Way collides with some other galaxy. The impact between two supermassive black holes could turn the Milky Way and that other galaxy into giant elliptic galaxies. And then that form turned back to a spiral galaxy. 

That means light travels faster or without standard disturbance. If that model is true, the energy travels faster away from the Milky Way's edge than in normal galaxies. That means that this thing makes it necessary to adjust the cosmological models. The thing is that the Milky Way is not as typical a galaxy as we wanted to think. 


But the problem is that the young universe was different from the universe. Where we live. The density in the young universe was higher. The difference between energy levels were smaller. And that means energy moved slower in that hotter universe. Maybe those three red galaxies were the first galaxies that formed. Those galaxies named S1, S2, and S3 are interesting because they are so big. Those galaxies are larger and heavier than researchers think. 

The major question in the element formation is this. Did elements form before stars? That means: were there some other heavier elements that existed before the first stars were born? The model is that things like collimations. of neutron stars form heavy elements. So if we think that black holes existed before stars those black holes could collide and send shockwaves that can turn hydrogen also into heavy elements. 

The question about the galaxies and planetary formation is when the first planets start to form. Or rather, when the first solid elements formed. For a long time, people believed that the stars were the only things that could form heavier elements than hydrogen. But then researchers noticed. High-energy reactions can form heavy elements like gold and iron. 

The neutron star collimations make the pressure wave that forms fusion and those heavier isotopes. That means it's possible that a black hole's relativistic jets can also push light atoms like hydrogen against each other and form fusion and heavier elements. That means heavy element formation doesn't need stars. They need only an energy punch that creates the fusion. 

When we think about supernova explosions there the intensive pressure- or shockwave travels through the universe. That impact front creates the fusion reaction that can send energy into those bubbles. And that energy is the thing that pushes material and weaker quantum fields into the form that we call singularity. A black hole's plasma halo is an interesting thing. But the same way. We can think that the event horizon is the gravitational halo around the black hole.
