Below this text is the link to the article, what tells lots of things about attitudes with something

Why every physicist would always repeating Einstein's Special relativity? There is a difference between theory and metering, and the reason for that might be a really interesting thing. One answer for that might be the Feynman's virtual photon, what wavelength causes that the photon would travel between two points in a longer time than electron because of photon travels a longer distance, but the speed would be the speed of the light.

So Feynman's virtual photon doesn't break the natural laws. But this kind of things is opening one very interesting thing in the universe and theories. That thing is that there are people, who would think that theories are things, what nature must follow. When we are thinking about photon and the mass of the photon, we must consider one thing. If photon would not have mass, that particle would not have existed. 

And everything that is existed must have a physical form, without mass the photon would not have impact energy, and photon rockets and lasers would not work. So if photon would not have mass it would not have existed. Solar sails are using the gas what comes from the Sun for giving thrust, so they are not photon rockets. Photon rockets are using light for giving thrust and the specific impulse of that rocket would be 300 000 meters per second. That thrust is low, and that's why photon rocket must accelerate near the speed of light by using some other energy source. 

Because of Einstein's theory of Special relativity is saying that nothing can travel faster than the speed of light, that thing would be the cornerstone in this kind of articles, where the metering results are falling because of some theory says something. And that is the reason, why the metering results must be wrong. The universe is the thing, what must follow theories. 

And if something else is happening, that thing must be forgotten. The problem with physics is that everything must be shown in calculations. Even if the metering results would be different than the theory, we must fix those results to follow Einstein's Special relativity or we are in big trouble. If something will break the holy formula, that thing would be a shock for the entire world.

So why the General Relativity cannot be used to explain this? The General Relativity made by Albert Einstein for explaining the differences with calculations and the meterings in the orbiting trajectory of Mercury. 

The Special Relativity is the thing, what would explain the traveling of photons in the straight universe, and that means that is suitable almost every places in the Universe. But near the massive objects and moving in the thicker gas the neutrino might cross the photon because of the Feynman's virtual photon theory. That theory would not break even the Special Relativity.

How to deny the flight noise?

How to deny the flight noise?

Making the silent helicopters and aircraft is one of the most important tools for denying the flight noise, and also turbines, what are used in those vehicles can easily turn to use the hydrogen as the fuel, what makes possible to create the aircraft and helicopters, what will not create the pollution at all. And the thing is that making hydrogen by electrolysis is one of the most effective ideas for decreasing the production of carbon dioxide.

But how clean that fuel is depended on the way, how to produce the electricity. If the production of the hydrogen happens by low-polluting or green energy, the system would remove carbon dioxide immediately. But the sound is the problem of turbine vehicles are they traveling on the highway or in airborne. And the most important question for the aircraft manufacturers is, "how to make a silent helicopter or aircraft"?

One way to create that kind of machines is to silence the sound by using the active sound denying technology. This technology bases the idea, that the very well targeted thin spot sound, what denies the other soundwaves to travel cross those lines. The system might work by using the LRAD- or targeted sound system. And that thing would make the airfields and airborne devices noiseless.

The idea is based that if between the object and observer would create the barrier by using the same frequential sound what the rotor or motors send is possible to deny the sound waves travel to the observer. In this case, the pressure or sound waves just turn the sound away from their route, and that means that the air molecules what are transferring the sound would just join the main flow of the sound, what comes from the side.

If that kind of system would install in the helicopter, the system would make it silent, and that thing might be interested also military personnel. The system would be interesting and in theory quite easy to make. The only thing what the engineers must be done is to put the high power loudspeakers on the body of helicopter or aircraft.

And if the vertical sound would travel with the same frequency with the sound, what comes from the turbines and rotor, would that system create the sound shield, what denies the sound traveling to ground. When we are thinking that kind of systems, the large areas like cities can cover by using this system, what can be connected to some tower, but the thing is that this system also denies the birds coming through that layer, and that is a very big problem with those things.

The sound what is used must be so loud, that it will blow the sound of the power system away from the track. And that would make the noise pollution in that altitude, which means that if the sound will hit to the hill, that thing might cause injuries for people or animals, what would accidentally go in the effective zone of the sound.

Six clicks separate people from each other.
