Writing about speed

Can some object cross the speed of the light? The answer is "yes", but people are not normally thinking about how that thing happens. The easiest way to cross the speed of the light is to make it virtually. That virtual crossing of the speed of light means the researchers just put the proton and electron travel to the opposite directions in the particle accelerator. If the speed of both of those particles is 90% of the lightspeed when they are impacting. The impact speed is 1,8 times the speed of the light. (Speed of proton+speed of the electron). The proton has a positive electric load and the electron has negative electricity, which means that impacting those particles is an easy thing. 

The idea is that the particle that is traveling with the speed is near the speed of light in a vacuum. And then it hits gas or other material where the speed of the light is lower than the speed of the particle in a short moment it would travel with the speed what is higher than the speed of light. The idea in this kind of crossing is that the speed of the light is not stable. 

It depends on the medium, and in the vacuum, the lightspeed is 299792458 m/s. But when the particle hits the glass it's speed is slowing to 200000000 m/s. The Large Hadron collider accelerates electrified (ionized) atoms to the speed of 299 762 478,75 m/s. That is 99,99 percent of the speed of the light(1). If the Large Hadron collider shoots electrons or atoms into the glass with the speed of 99,99 percent of the speed of light to glass that particle will break the glass because during slowing that particle must deliver energy to that particle. 

And because of the slowing of the particle that has mass cannot be limitless during the slowing that particle travels with speed what is higher than the speed of light. The question is can the multi-atomic object stay in one piece during that process? When the particle has mass and it hits the medium, it starts slowing and during the slowing process, the particle must transfer its energy in the medium.

This is calling the "borderline crossing", and things like neutrino detectors are benefitting that thing. When the neutrino is impacting the water in the neutrino detector, it sends the blue-light shock wave during the slowing.

A little bit about the speed of gas

The description for the term "sound" is it's only a wall of the moving gas.  So can the soundwave what is the fast-moving gas travel faster than the sound? The question can turn to model "can molecular gas travel faster than the speed of sound? The answer is "yes"!. The speed of sound is not very high. If we are comparing it to the speed of light. The speed of sound is 343 meters per second. 

And the speed of light is 299 792 458 m/s. So the sound is the movement of molecular gas. When the aircraft travels with supersonic speed people on the ground are hearing the "sonic boom". The sonic boom means that the molecules that the aircraft turns away are traveling by the impact speed between air molecules and the supersonic aircraft. When aircraft hits the air molecule it pushes it like a tennis racket when it hits the ball. The speed of the ball depends on the speed of the tennis racket. 

The speed of gas molecules can cross the speed of sound very easy, and molecules make that almost every day. During explosions, the molecules are traveling outside the explosion with the speed of the firefront. And that means the shockwaves of the nuclear explosions can travel at an extremely high speed. That is multiple of the speed of the sound. 

The speed of ionized gas that comes out from the Sun is many times higher than the speed of sound. The fact is that if we think that the sound is the movement of the molecular gas or ions. That means that the sound can travel at a speed almost the speed of the light. In this case, the "sound" is the term that means the pressure barrier, which travels in the Universe.

Plasmonic waves can make new waves in quantum technology.

"LSU researchers have made a significant discovery related to the fundamental properties and behavior of plasmonic waves, which can lead ot the development of more sensitive and robust quantum technologies. Credit: LSU" (ScitechDaily, Plasmonics Breakthrough Unleashes New Era of Quantum Technologies) Plasmonic waves in the quantum gas are the next-generation tools. The plasmonic wave is quite similar to radio waves. Or, rather say it, a combination of acoustic waves and electromagnetic waves. Quantum gas is an atom group. In those atom groups, temperature and pressure are extremely low.  The distance of atoms is long. And when an electromagnetic system can pump energy to those atoms. But the thing in quantum gas is that the atoms also make physical movements like soundwaves. It's possible. To create quantum gas using monoatomic ions like ionized noble gas. In those systems, positive (or negative) atoms push each other away.  When the box is filled with quantum gas and som...

What is the difference between TR-3A and TR-3B? And are those planes real?

What is the difference between TR-3A and TR-3B? And are those planes real? Is TR-3B (0) "Black Triangle UFO" or is it only the piece of paper?  The study project, what is used to create advanced ideas for use of the nuclear-powered aircraft. Or is it the study project or black budget aircraft, where lost 2,3 trillion dollars (1)of the stealth bomber were gone. In this text is things, that might seem very difficult to accept, and when we are thinking about things like doubling the object or making it smaller by using huge layers of energy, nothing denies to test those things. But were those tests successful, there is no data about that in public Internet, so we must say that things like doubling the human or aircraft can be tested, but the results can be unknown.  But in the source two is the tale, what seems like impossible, those men, who got Noble Prize put at first time one atom to the box, and hit it with photon one photon in the box and hit it with t...

The interesting coincidence between USS Sea Shadow (1982) and CSS Virginia (1862)

Image I The interesting coincidence between  USS Sea Shadow (1982) and CSS Virginia (1862) Far away from its time is the thing, that you might notice when you see those two images. The upper one (Image I) is portraying the modern naval USS Sea Shadow (IX-529)(1) experimental Stealth ship, which was created by Lockheed-Martin, and the image below (Image II) is portraying the CSS Virginia (2), the ironclad from the Civil War Era. The thing why the hull of the CSS Virginia, what is ironclad from 1862 is that the ammunition of the cannons would not transfer their impact energy to the hull of the ship. And the reason why Sea Shadows hull has this form is that it should point the radar echo away from the hull.  The thing that I must say that CSS Virginia is far ahead its time because that structure is effective against the explosive ammunition, and the slanting armor of tanks like T-34 and Sherman have made them effective. But for some reason, the use of slanting ...
