Graphene could be ideal for quantum bits.

Graphene can form new types of quantum bits. There are two ways to use graphene as qubits. In the first model, the carbon atoms trap qubits into the electric field in the graphene structure. In some other models, the system puts electromagnetic fields around carbon atoms into superposition and entanglement.

Graphene is a carbon atoms 2D network, and if the carbon atoms or their quantum fields can turn into the superposition that makes the new visions for the room-temperature quantum computers. Superposition means that particles oscillate with the same frequency.

In regular quantum computers, qubits are stabilized at a very low temperature. But it's possible to make this stabilization by using high-pressure materials. Some materials can turn superconducting near zero Celsius and at reasonable pressure. The problem with those materials is that they are expensive.

The graphene on microchips can turn into superconducting or stable conditions using two ways.

1) The system can press that graphene by using lasers.

2) Or by using acoustic systems. In the last ones, graphene is between carbonite crystal layers. The pressure system presses those layers together.

This type of microchip can act as a tool. That transforms traditional bits into qubits. The system can involve a graphene layer. That the lasers or acoustic pressure systems transform into qubits.

The problem is that the material turns superconducting in a very high pressure. The 2D graphene can turn into superconducting by pressing its lasers. The 2D structure will not break in the high pressure that comes from both sides of that structure. And that system makes it possible to create microchips.

There is a graphene layer on them. Then the computer system just presses that graphene layer with pressure. That is created by using lasers or acoustic systems. In acoustic systems, the monotonic sound presses the gas flow that travels over carbonite chrystal. Then that chrystal presses the graphene.

The superconducting condition makes it possible that the system can control the qubits, and information that flows in it. The problem with qubits is that they are sensitive to oscillation. Oscillation is the thing that causes problems with quantum entanglement.

In quantum computers, information is stored in qubits. The qubit is a particle and information is on it as layers. Then the system transports information between point A to the point by putting two particles into the superposition and entanglement. Then the entanglement. That is the power field that connects those two superpositioned particles starts to transport information.

The entanglement is like a strap between particles. And those particles are like gear wheels. So the superpositioned and entangled particles are like gear. The superposition means that the particles oscillate with the same frequency.

The reason, why those particles must be in superposition is that the entanglement or strap that transports information jumps off those particles if they oscillate with different frequencies. So that's why those particles are frozen near zero Kelvin degrees.

But there is another way to make stable conditions. It's possible. That lasers can push the particles from different directions. And that thing stabilizes qubit. Graphene is the most promising thing for that purpose because it's a 2D material.

Black holes cause a virtual redshift because gravitation stretches the wavelength near them.

At the beginning of this text is a film about the redshift of black holes. Gravitation stretches light, and that means gravitation fields are pulling waves longer. That thing is called the gravitational redshift. As you can see from the film, the black hole stretches radiation and distorts the redshift. Gravitational redshift, or virtual redshift, means that a black hole might seem to be at a longer distance than it is. The film shows the redshift of the star that orbits a supermassive black hole. But all other black holes interact the same way. The event horizon is always constant. At that point, the black hole's escaping velocity is the same as the speed of light. So every black hole interacts basically in the same way. And it's possible to apply that model to all black holes irrespective of their size. Is gravitation the thing that forms dark energy? That thing seems somehow strange. But when photons and other particles are traveling through the ball that forms the visible

The shape of the brain means more than neuro connectivity.

Well, we might say that the brain is in its entirety. Another thing is that all things in the brain have some kind of purpose. The shape of the brain and, especially, the folding of the brain shell are extremely important things. Those folds are expanding the brain's surface areas. And the brain shell has a primary role in the thinking process. The surface area of the brain determines how large the cerebral cortex is. And in a large cerebral cortex, there are a large number of neurons. But as I just wrote, the brain is in its entirety. "Researchers have discovered that the shape of a person’s brain significantly impacts thought, feeling, and behavior, overturning the prevailing emphasis on complex neuronal connectivity. Utilizing MRI scans and the principle of eigenmodes, they found that brain function is closely linked to its geometric properties, much like how the shape of a musical instrument determines its sound, offering new avenues for exploring brain function and diseas

New nanomaterial is 4 times harder than steel. And, at the same time 5 times lighter than steel.

New nanomaterial is 4 times harder than steel. And, at the same time 5 times lighter than steel. The new material is the hollow glass fiber with DNA molecules inside that structure. Or as you see from the image. The glass fibers are on both sides of the DNA. DNA molecule is the thing, that involves the genetic code of the cells. Genetically engineered cells can make DNA, and those molecules can used as the nanomaterial's structures. DNA manipulation makes it possible to create new types of extremely strong materials. And those materials are stronger than steel and lighter than it. DNA molecules can act as nano-size springs. And in some visions, genetically engineered cyborg cells like cyborg macrophages can make extremely long DNA molecules. And then they can just use those molecules as spears that can pierce wanted cells. Or those cyborg cells can also dumb targeted cells full of the DNA that terminates them immediately. The DNA and nanotube combinations can also act as DNA-b
