Tantalum disulfide and laser rays are giving new information about metastability.

The image above this text shows how laser stresses 2D tantalum disulfide crystal. Researchers are found new mysterious hidden quantum phrases in the tantalum disulfide. And the question is can this kind of quantum phrase exist in other materials like graphene? Or is that quantum phrase existed only in the metallic atoms? (1)

There is the possibility that the laser impulses can also use as a press that will remove the higher level of carbon atoms from the graphite and transforms it into graphene. The lasers can be the ultimate tools for creating new 2D materials that are needed in a new type of electronics laser rays will be shot through the graphene layers.

In some of the most modern systems, the information will transfer to those laser rays by stressing graphite by using energy. That system can give energy stress can by using masers or lasers with different wavelengths. The system is two graphene layers where laser travels between those layers.

The researchers stressed tantalum disulfide by using laser light for testing the metastability. The metastability is the key element in the quantum computer. The system must have a different energy level than its environment so that the quantum computer can separate qubits from the environment. The image above shows how the laser system stresses the tantalum disulfide with energy. And that thing makes it possible to observe metastability in 2D quantum systems.

If the quantum computer can maintain the quantum metastability long time. It would not re-adjust itself so often. "In chemistry and physics, metastability denotes an intermediate energetic state within a dynamical system other than the system's state of least energy". (Wikipedia, Metastability). Things like avalanches are a good example of the metastable system. They are locked to a higher energy level until something removes that lock and allows energy transfer out from the system.

Metastability in the tantalum disulfide is helping to understand the birth and evolution in the hidden quantum phase. Metastability means the case or conditions where a physical system (quantum etc.) can stay longer at an energy level that is not the lowest possible.

The things like avalanches and rolling balls are introduced as an example of metastability in the systems. In those cases, the system takes energy from outside like an avalanche that falls from mountains. When the slope ends. The system will reach all its extra energy to the environment.

Opposite metastability means that the energy level in the system is lower than its environment. And one example of this thing is the ice bite that is carried in the house. The opposite metastability means that the temperature of that ice is lower until energy flows to it from the environment.

The LK-99 could be a fundamental advance even if it cannot reach superconductivity in 400K.

The next step in superconducting research is that LK-99 was not superconducting at room temperature. Or was it? The thing is that there is needed more research about that material. And even if it couldn't reach superconductivity in 400K that doesn't mean that material is not fundamental. And if LK-99 can maintain its superconductivity in 400K that means a fundamental breakthrough in superconducting technology. The LK-99 can be hype or it can be the real thing. The thing is, anyway, that high-voltage cables and our electric networks are not turning superconducting before next summer. But if we can change the electric network to superconducting by using some reasonable material. That thing can be the next step in the environment. Superconductors decrease the need to produce electricity. But today cooling systems that need lots of energy are the thing that turn superconductors that need low temperatures non-practical for everyday use. When the project begins there is lots of ent

Black holes, the speed of light, and gravitational background are things that are connecting the universe.

Black holes, the speed of light, and gravitational background are things that are connecting the universe. Black holes and gravitational waves: is black hole's singularity at so high energy level that energy travels in one direction in the form of a gravitational wave. We normally say that black holes do not send radiation. And we are wrong. Black holes send gravitational waves. Gravitational waves are wave movement or radiation. And that means the black holes are bright gravitational objects. If we can use water to illustrate the gravitational interaction we can say that gravitational waves push the surface tension out from the gravitational center. Then the other quantum fields push particles or objects into a black hole. The gravitational waves push energy out from the objects. And then the energy or quantum fields behind that object push them into the gravitational center. The elementary particles are quantum fields or whisk-looking structures. If the gravitational wave is

The CEO of Open AI, Sam Altman said that AI development requires a similar organization as IAEA.

We know that there are many risks in AI development. And there must be something that puts people realize that these kinds of things are not jokes. The problem is how to take control of the AI development. If we think about international contracts regarding AI development. We must realize that there is a possibility that the contract that should limit AI development turns into another version of the Nuclear Non-Proliferation Treaty. That treaty didn't ever deny the escalation of nuclear weapons. And there is a big possibility that the AI-limitation contracts follow the route of the Nuclear Non-Proliferation Treaty. The biggest problem with AI development is the new platforms that can run every complicated and effective code. That means the quantum computer-based neural networks can turn themselves more intelligent than humans. The AI has the ultimate ability to learn new things. And if it runs on the quantum-hybrid system that switches its state between binary and quantum states,
