NASA's ingenuity helicopter made its 33rd mission on Red Planet.

"NASA’s Ingenuity Mars Helicopter acquired this image using its navigation camera. This camera is mounted in the helicopter’s fuselage and pointed directly downward to track the ground during flight. This image was acquired on November 6, 2021 (Sol 254 of the Perseverance rover mission) at the local mean solar time of 12:06:00. This was the date of Ingenuity’s 15th flight.

NASA's Ingenuity helicopter made its 33rd mission to Red Planet's atmosphere. The interesting detail in this mission is one piece of foreign debris that is found on the surface. That debris is one of the most interesting things what that small helicopter has seen. 

But Ingenuity itself is an interesting system. A similar system that uses nuclear batteries can use to map the high atmosphere of gas giants like Jupiter and Saturn. And also Ingenuity can use to map the Venus and Titan moon.

One of the most interesting questions is could the Ingenuity or Perseverance find life on Mars? 



The fact is that there is remaining organic material and structures that look like ancient bacteria. There are theories that Mars has changed its trajectory during history. Also, that planet faced even more violent geological upheavals than Earth. Mars lost its entire lithosphere. 

So there is a possibility. That on Mars-planet was some kind of primitive lifeforms like procaryotes that are similar to cyanobacteria on Earth. But that thing requires more research to confirm. 


If the positions where researchers find those bacteria are very rare. That tells they are coming from somewhere else than on Mars. But where lifeform can come from? One possibility is Earth.

 

There is the possibility that the bacteria traveled to Red Planet with probes that are not well-sterilized. But that thing means. There should be DNA (or RNA) molecules in the bacteria remnants. If bacteria is transferred to the Martian rock, that requires its living. If there is no DNA or RNA remnant, that means there should be some reason for that. 

Of course, the UV radiation of the Sun can explain why some bacteria are lost their DNA. But if the position where those fossils are found is mainly in shadow. That means the UV radiation will not reach those bacteria. 

The requirement that the UV radiation destroys the DNA or RNA is that the radiation can touch that molecule. If that molecule is in shadow that denies the possibility that the UV can destroy it. 

One interesting place where researchers can search for life or remnant of lifeform is the asteroid or dwarf planet Ceres. There is some kind of cryovolcanic activity on that asteroid. 

If there are similar bacteria or bacteria remnants that are found on Mars, that thing causes a re-estimation of the place where the first organisms came to Earth. But the first thing is that researchers must make sure that the fossils are bacteria remnants. Without DNA or RNA bites that thing is almost impossible.

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,
