Hypersonic flight will be the next fundamental advantage in aviation.

Hypersonic flight is the key to the next-generation missiles and aircraft as well as space shuttles in civil and military sectors. Aircraft that can jump outside the atmosphere and then return can be the next-generation solutions. There are rocket-based hypersonic missiles already in use. But the Scramjet-powered systems are new.

Hypersonic missiles can launch from aircraft or by using a rocket. They can equip with powerful microwave systems that can damage electronics or even melt targets.

Launching those weapons from aircraft is similar to a regular cruise or air-launch ballistic missile. If the weapon is shot by using a ground-based rocket the process is a little bit different. The rocket will jump outside the atmosphere. And then the hypersonic missile can get enough speed. That the scramjet engine can start. The scramjet or hypersonic ramjet-based systems can also launch from the regular runways.

There are three versions of that kind of engine system. The first one is that the aircraft lifts off by using regular turbojets. Then when the speed is high enough the aircraft transfers to use the ramjet engine. And when the aircraft's speed rises to Mach seven or seven times higher than the speed of sound. It starts the fuel injection to the scramjet engine.

There are no moving parts in the scramjet engine. The airflow or the fuel-air mixture's friction causes heat.

That heat ignites the fuel. Which can be liquid hydrogen. The liquid hydrogen can also decrease the temperature of the core of the engine and aircraft.

And the problem with scramjet is that the speed of that engine must be over Mach 6 so that the scramjet can ignite the fuel. Another version is to make the airflow through scramjet with extremely high speed.

That thing can be happened by connecting the hypersonic wind tunnel behind the scramjet engine. That wind tunnel can pull the air through the scramjet, and the friction will engine the fuel.

But there is the possibility to create the ion scramjet. The engine ionizes air at the front of it. And then the magnetic track will pull those ions back. The magnetic track requires electricity. That's why portable lightweight nuclear reactors are promising tools to give fuel supply for that kind of device.

The hypersonic stealth bombers are the most capable systems in the military world. Those bombers can attack very fast on every side of Earth. The large-size hypersonic aircraft can also transport people and cargo all around the Earth very fast. And if the hypersonic engines use hydrogen as the fuel they have no carbon emission.

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,
