   It's not the same who owns the sharpest atomic clock.

The observation of dark matter requires an extremely sharp time measurement.

The new atomic clock, which bases the idea that atoms are hovering in the electric field is an amazing tool. It can use to measure the dark matter and photon tracks. The dark matter reacts only by gravity, and the effect of this thing is that it will curve the tracks of photons.

So for making observations about dark matter researchers must calculate the track of photons and then compile the calculated track with real tracks, and that thing requires extremely high accurate measurement of time. During this kind of measurement, the researchers are using the distant galaxy. First, they mark the position of the distant galaxy very sharply and calculate the movement of that galaxy. Then they will compile the difference of the measured change of the point of that galaxy, and compile those changes with the calculations.

The idea is simple. If there are dark matter clouds at the tracks of photons, what is coming from that distant galaxy. Those clouds are causing the curving to the tracks of photons. But at first, the molecular clouds and other massive objects must map between that galaxy and Earth. The normal material is also curving tracks of photons. And that means that the weight of galaxies, stars, and molecular clouds must measure and include the formulas.

Those are used to calculate the tracks of photons. When the effect of material objects has eliminated the rest of the difference between the calculated tracks and real tracks are caused by dark matter. But those measurements require extremely sharp instruments like powerful computers, which can handle the interaction of billions of objects, and extremely sharp clocks, which are used to calculate the difference between calculated and real values.

The atomic clocks are used also in many other measurement tools, and they are used to calculate the echo of the laser rays. The atomic clock measures the time, that the laser ray would take to travel between two points. And that thing makes it possible to make sharp maps from huge distances.

Atomic clocks are the ultimate hacking tool.

When the computer tries to break the pin code or password it can simply send certain marks to the receiving computer. Then the hacking computer just measures the time of echo of the receiving computer. If the letter or mark is right the echo would take more time. And that time can measure by using an atom clock.

If the marks are sending by one to one that thing makes it the offensive computer "easy" to measure the answer time. The thing that causes the difference in the answering time is that the password is stored in the database. And when the system finds the correct mark it would also test the next mark in the line. If there are more correct letters in a line, the system reads the database longer time.

The " linear multi-key system" means that each letter of the password has its database. And the data is driven in the system in linear form, which means the echo time at the point of the certain mark cannot be measured.

So how to deny this kind of attack? There is a couple of ways, and most commonly the attempts to log in to the system are limited. But another version is to use linear secrecy. The linear or qubit-based secrecy is a little bit complicated to make than some regular secrecy, where the marks are input in a row. In linear secrecy, each of the marks has its database.

Artificial intelligence is an ultimate protector for data security.

In linear secrecy, marks are first to read to the buffer. And then they will transmit to the databases. The fact is that the length of the password should be open, and that means there should not any kind of limits. So the 25 first marks can drive to separate databases, and rest to the one big database, which makes it possible to use the free length passwords.

Or the artificial intelligence-based system can create the database for each mark automatically. That kind of algorithm is making data security less vulnerable than ever before. But the data security is the race between ultimate secrecy and ultimate code breakers. So the thing is that even the best secrecy can be a break.

Antimatter motor

Antimatter motor Antimatter would be an effective fuel for interstellar spacecraft Antimatter would be the most effective power source in the world. It will be the most suitable motor for interstellar spacecraft, but the problem is that thing is very reactive. And actually one of the biggest problems with this kind of motor is that the gram of antimatter would turn the entire planet to the molecular nebula. So this kind of motor can produce only outside of our solar system. Producing antimatter would need large particle accelerators, and that kind of systems might look like giant donuts, what is floating on the space. There are two ways to create the antimatter motor, one is to store the anti-ions in the magnetic bottle, where the pushing magnetic field will keep those ions away from the wall of the bottle, and then the antimatter would conduct to the water or some other particle. The huge explosion or annihilation reaction would send the rocket to a very high speed. The antimatt...

Thoughts about strong leadership

Thoughts about strong leadership Everybody knows, how the dictators would rise in the power of the nation, and the thing what makes people supporting those persons is that they offer strong leadership as the way to make nation proud. And also they have always the same parroting, the foreigners and other nations have a too strong influence in the country. But what makes those persons like some Robert Mugabe or Kim Jong Un to think that they are only possible leaders, and why people would need them? Why there is nobody else allowed to try to come to the head of the state, or even try to challenge those leaders? If they are so popular as they want people to think or believe, why they don't tolerate any kind of opposition if they are done so good and big actions for their people, that they are celebrated in every home in their country. The thing that would return the morale and spine for the nation is the strong leader, who would put the state back in order and row. The thing is ...
