ILLUMINA-T the new high-power laser-communication system can improve and make satellite communication more powerful.

ILLUMINA-T laser system uses ground-based lasers-communication tools, aimed at targets by using orbital mirrors. Laser communication systems are not so easy to jam as radio waves. Laser rays can be used as a very high-secure communication tool. In some visions, the hollow laser ray covers information carrier laser rays. Because information carriers are traveling in the hollow laser ray, stealing information is very difficult.

If somebody tries to push some sensor through the outer laser ray the system sees changes in the power of that protecting laser ray.

That means they see if somebody tries to steal information by eavesdropping messages. And that makes laser communication secure.

In some versions, laser ray protects the radio maser beam in that channel. That allows the system to communicate through the wall.

The limits of the regular laser rays are that they cannot travel through walls without making holes into the walls. This is why there is lots of research about X- and gamma-ray lasers. Those lasers can transport information through walls without harming it.

But similar technology that is used in ILLUMINA-T can be used in laser weapons. The difference between laser communication and laser weapons is the energy ray's power. In some space-weapon models, ground-based high-power megawatt-scale laser systems send their laser rays to the mirrors at the orbiter.

The power of those laser rays would be high enough that they destroy satellites. In those weaponized models, the laser system is static, and the mirrors at the exhaust tube in front of the mouth of the laser aim the laser rays into mirror satellites.

If those lasers are positioned in an X-shape formation those mirrors can cover 360-degree areas. The same lasers can be used as the message lasers, and if the system must use them as weapons they must just adjust their power to a destructive level. The most powerful lasers can produce over 2000 terawatt power.

That power will break those laser mirrors immediately. But it is possible. These kinds of ultra-powerful lasers can be dangerous also for ground targets.

Even if orbital mirrors are single used in that power level they still have time to aim laser ray into the target. If a 2000 terawatt laser system shoots its beam through the orbiter, it could destroy at least high-flying aircraft. The laser weapon can also as a scientific tool, and only if that weapon is needed the operators can put the mirrors in the right points and those laser rays can conduct out from the laboratory by using channels that are made for that purpose.

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,
