Hypothetical faster-than-light particles. And Cherenkov radiation.

    Hypothetical faster-than-light particles. And Cherenkov radiation. 

Cherenkov radiation proves that nothing that has mass can't slow unlimited. When a particle that travels so close to the speed of light impacts things like water or air, it must release its kinetic energy as radiation. In a very short moment that particle travels faster than the speed of light in that medium.

But what happens? If we think that the proton impacts the atmosphere with its maximum speed at vacuum. The medium starts to slow proton. In that process, the quantum field around the quarks slows and then quarks inside protons continue their travel with the same speed as they traveled in a vacuum. Then the slowing quantum field moves backward and those quarks impact with the front side of the quantum field that we call proton.  

Same way. An electron swings forward when it hits its atmosphere. The swinging movement of the internal structure of particles continues to travel when their quantum fields start to release energy to the medium, or the receiving atom's quantum field. 

Cyclotron radiation forming. When electrons change their trajectories in particle accelerators they send photons. Or actually, electrons forming quantum whirl called virtual particles after them. And when those whirls collapse, that impacting quantum field forms a virtual particle in the middle of that whirl. 

There is a possibility that tachyons form in cosmic bubbles or cosmic voids. There the quantum fields are weaker than usual. And that means they don't slow particles similar way as in the "regular universe". When we think about the neutrino anomaly in the OPERA (The Oscillation Project with Emulsion-tRacking Apparatus) test where neutrinos traveled faster than light, there is the possibility that this thing happened because of measurement error. 

Or maybe some neutrino formed in a short-term quantum whirl called a virtual particle. If neutrino forms in the virtual particle, it can travel faster than usual because short time it's in an area, where quantum fields don't slow its speed. And failing whirl pumps energy to that neutrino. 

So could this kind of effect explain a hypothetical faster-than-light particle called tachyon? In tachyon theory. Tachyons formed at the the young universe's edge. There were no quantum fields that could slow the speed of those tachyons. That thing doesn't explain why tachyons could be inside our universe. 

But in some other models, tachyons are forming at the edge of the universe. Sometimes wave movement and some particles travel outside the universe. Outside our universe energy level is less than in the universe, and that means the energy level outside the universe is lower than the energy minimum in the universe. 

Time dilation has no effect in that space. And particles turn to wave movement very fast. When two particles are close enough to each other or some wave movement, that explosion where the particle turns to wave movement turns the whirl. The gravity that acts between superstrings that are extremely thin energy fields causes the quantum whirl collapses. 

Or the ends of the string impact with the straight-moving part of the superstring. And that thing causes the flash or forms a photon that is faster than light. The universe's gravity will pull those particles into it. Or the superstrings are turning to the universe and the universe's quantum field forms those whirls. The collapsing whirls form a photon-looking structure called still hypothetical tachyon. 

One of the explanations for tachyons is the Multiverse. If there are some other universes, radiation that comes from them can form tachyons when that radiation hits radiation that travels out from our universe. If those other universes mass is lower the radiation or wave movement that travels out from them travels with higher speed than radiation or wave movement that travels out from our universe. 

And when those radiations impact. That thing can form tachyons. If tachyons exist and their speed is higher than the speed of light, interaction with those particles is so short that they are hard to detect. 

And the reason why tachyon can travel faster than the speed of light is simple. It's forming in an area. Where no quantum fields can slow it. That means cosmic vacuums can also form tachyons from impacting quantum fields. 

When a high-energy particle hits the atmosphere energy starts to travel from a higher-energy particle or its quantum field to a lower-energy actor. When a particle hits a medium its quantum field turns elongated. This thing has caused a theory that a hypothetical faster-than-light particle called Tachyon is like some kind of tape. 

If the tachyon is a long, tape-looking particle that explains why it's hard to detect. The impact area of the tachyon would be so small that it tunnels itself through another particle. And when a flat and long tachyon travels in space tachyon's longitudinally horizontal form harvests energy in that structure. That structure acts like a laser. 

So tachyon receives side coming wave movement. And that turns its energy level higher than other particles. That means the tachyon sends radiation that could be dark energy. Tachyon harvests energy like laser rays. And then. Tachyon releases it at the same speed as it gets energy. Or maybe tachyon gets more energy from its environment than it can release. 

When the tachyon closes other particles that energy pushes it away. When the tachyon releases wave movement. It forms small quantum-size cosmic vacuums. They act like vacuum bombs. Those virtual particles could act like gravitational centers. And that means we cannot see dark energy sources, because it's in the virtual particles, that source could be hypothetical tachyons.
