Jamming the GPS is not as easy as people think.





Russians are told that they can jam the GPS. The war in Ukraine has shown that jamming the GPS is not as easy as people think. The communication between GPS and satellite happens with multi-channel radios. So the system uses multiple frequencies at the same time. 

That's why jamming the GPS is more difficult than people expect. The data security of those systems is very important. And maybe NATO uses different GPS in exercise than in real situations. That makes jamming of those systems extremely difficult. 

When people are looking at the Russian sea-launch missiles they are not very accurate. There is the possibility that small drones or special warfare teams are taking the radar transponders to targets. That thing makes targets seem brighter on the radar of the missile. And people expected Russians have those transponders. That thing can give the radar-homing missile higher accuracy. But Russians seem to have not those transponders. 

The problem with HiMARS and other precision-guided weapons is that if Russians get one of them. They can find out those frequencies. Another thing is that Ukraine will not maybe need anything more than 20-50 HiMARS launchers. People always asked, why Ukraine would not get let's say about 300 HiMARS? Have you ever known about the apportioning of firepower? 

That means the firepower would be limited to the necessary level. The GPS tells the precise point of the HiMARS to the deliverer of the system. But there is always the possibility that some Ukrainian criminals try to sell those weapons to Russians. Those weapons cannot use against Ukrainians or NATO. But they can give information about what the Russians need to break the GPS. 

The answer is there is always the possibility. Those Russians capture those systems. Another fact about the HiMARS is that weapon manufacturers are making more of them if there is a need for those systems. When we are talking about the HiMARS and other types of weapons we must realize that the U.S stockpile of those systems is not public information. 

And there is always the possibility that some Wikipedia data about those systems is wrong. Another thing is that the only allowed sources for comments on the war are public data. Uncovering classified information can cause big problems for national security. So Wikipedia and some FAS.Org type pages are allowed sources. The classified and top secret files are not public sources. They are not also allowed to use in commentations. The links below this text are going to news that is in Finnish.

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,
