Neutron stars can involve dark matter.



Researchers use supermassive and massive objects to observe the dark matter. The dark matter is the gravitational effect, and researchers use things like galactic clusters to see how the dark matter bends the light. Researchers calculate how much those objects should weigh. Then they, see how much the object turns or blends the light in the gravity lens. That tells what is the real mass of the object. 

In some models dark matter or weakly interacting massive particles (WIMP) are inside all or some other particles. The idea for that is from the observation that protons involved charm quark. The charm quark is a more massive particle than a proton. That gave the idea that the charm quark might hover in protons. And the next idea was this. Maybe dark matter's WIMP particle hovers in some other particle. 

Because dark matter interacts with gravity as well as visible material. Researchers should find dark matter near massive objects or gravity centers. The thing that makes this mysterious gravity effect interesting is that, theoretically, the material can turn invisible, and dark matter is only one state of matter. But is it real material or is it some kind of virtual material? 


Above: Neutron is a composition of 1 up quark and 2 down quarks.


Above: Proton is a composition of 1 down quark and 2 up quarks.

The "lone quark" model: 


Protons involve two up quarks and one down quark. Neutron has two down quarks and one up quark. If that lone quark turns into its anti-quark material may turn invisible. 

It's possible that the up quark can transform into its antiquark in neurons, or the down quark can transform into its antiquark in the protons. That causes a situation in which the antiquark cannot find its mirror particle. In that model, the lone quark's transformation turns the material dark. 

In some models, there is the possibility that all other particles can create similar holes with electrons. The electron-hole is a positive point in the electron orbital. It's possible. Researchers can apply this model to eight color states in gluons. 

So can the quarks and gluons have similar abilities with electrons? In that case, the gluon or quark quantum charge can turn opposite. So the color charges or color states act like electricity in, and between electrons. And that means the gluon can create similar holes with electrons. 

Theoretically, a quark can form a quark hole when the quark turns into its antiquark. And if the antiquark cannot interact with its opposite or mirror quark there is no annihilation. Annihilation is possible only when a particle interacts with its mirror particle. 

And if the down quark transforms into its mirror particle in proton, or the up quark can transform into its antiparticle in neutrons it's possible. That the anti-up or anti-down quark doesn't find its mirror particle. And there should not happen an annihilation. 

In some other models, the charm quark in the proton can turn into an anti-charm quark. The charm quark hovers in the protons, and if that thing turns into an anti-charm quark, it might not find the mirror particle. But then another question is, can this thing turn material into dark?

Chinese innovations and space lasers are interesting combinations.

Above: "Tiangong is China's operational space station located in low Earth orbit. (Image credit: Alejomiranda via Getty Images)" (Scpace.com, China's space station, Tiangong: A complete guide) Chinese are close to making nuclear-powered spacecraft.  Almost every day, we can read about Chinese technical advances. So are, the Chinese more innovative than Western people? Or is there some kind of difference in culture and morale between Western and Chinese societies? The Chinese superiority in hypersonic technology is one of the things that tells something about the Chinese way of making things.  In China, the mission means. And the only thing that means is mission. That means that things like budgets and safety orders are far different from Western standards. If some project serves the Chinese communist party and PLA (People's Liberation Army) that guarantees unlimited resources for those projects. Chinese authorities must not care about the public opinion.  If we th

Iron Dome is one of the most effective air defense systems.

The Iron Dome is a missile defense system whose missiles operate with highly sophisticated and effective artificial intelligence. The power of this missile defense base is in selective fire. The system calculates the incoming missile's trajectory. And it shoots only missiles that will hit the inhabited area. The system saves missiles and focuses defense on areas that mean something. The system shares the incoming missiles in, maybe two groups. Another is harmless and another is harmful.  Things like killer drones are also problematic because their trajectories are harder to calculate than ballistic missiles. The thing that makes drones dangerous is that they can make masks for ballistic missiles. And even if those drones are slow, all of them must be shot down.  The thing is that the cooperation between drone swarms and ballistic missiles is the next danger in conflict areas. In the film, you can see how drones make light images of the skies. The killer drones can also carry LED li

The innovative shield that protects OSIRIS-APEX can also protect the new hypersonic aircraft.

"NASA’s OSIRIS-APEX spacecraft successfully completed its closest solar pass, protected by innovative engineering solutions and showing improvements in onboard instruments. Credit: NASA’s Goddard Space Flight Center/CI Lab" (ScitechDaily, Innovative Engineering Shields NASA’s OSIRIS-APEX During Close Encounter With the Sun) The OSIRIS-APEX probe travels close to the sun. The mission plan is to research the sun. And especially find things that can warn about solar storms. Solar storms are things that can danger satellites at the Earth orbiter. And the purpose of OSIRIS-APEX is to find the method of how to predict those solar storms. Another thing is that the OSIRIS-APEX tests the systems and materials that protect this probe against heat and plasma impacts.  The same technology. The researchers created for OSIRIS-APEX can used in the materials and structures. That protects satellites against nuclear explosions. That means this kind of system delivers information on how to prot
