Can we someday de-extinct species like the Tasmanian tiger (Thylacine)?


Thylacine (Wikipedia/ Thylacine)

The fact is that today de-extinction is impossible. There is the possibility that researchers could isolate the DNA from the corpses of mammoths or some recently extinct species like the Chrismas Island rat. But the fact is that the DNA that is in the skulls of those animals is hard to separate. The DNA would be damaged or there are connected viruses. So the result of cloning could look like a Chrismas Island rat. But it would not be a "real rat". 

There are many suggestions that extinct species will return to life by simply cloning those animals. The fact is that the result would not be perfect copies of the extinct animals anyway. The DNA of those animals could be polluted. And that means that even if the result will seem like Tasmanian tiger or Christmas Island rats (McLear's rat) they might not be those animals anyway. 

If we want to return extinct species to life we must realize that thing is easier to plan than make in real life. The problem is that the animals that are stored in museums are independent cases. And that causes that even if we can clone some animals population would be extremely small. And that thing causes degeneration. 

Another thing is that we don't know about the behavior of those animals. We would make individual animals but what happens if it's the only member of that species? Would that animal feel good? And could that kind of animal be safe? 

Technology is advancing. And that thing makes it possible to create synthetic DNA molecules. But the fact that there are billions of DNA sequences that must be made. When we are thinking possibility to return things like dinosaur's life, we must remember that if we connect some DNA of frogs or birds with the DNA of some dinosaurs the result would be a different species than the original dinosaur was. 

The thing is that finding the missing DNA sequences is difficult because there is no confirmed DNA of those animals. Where isolated DNA, can be compared. Nanotechnology and other things can make it possible to create synthetic DNA quite soon. New methods like the ability to erase single atoms from molecular structures are making it possible to create synthetic organisms. 

And that thing makes it possible to create synthetic organisms. Maybe those organisms are at the level of cells or bacteria. But the fact is that those things are the first steps on the road of nanotechnology and genetic engineering.

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,
