The coldest place in the universe unveils the secrets of antimatter.

"Borexino is a highly sensitive neutrino detector located at the Laboratori Nazionali del Gran Sasso in central Italy. Situated deep underground, it uses an ultrapure liquid scintillator to detect low-energy solar neutrinos and study the fundamental properties of neutrinos and solar processes.

The reason why antimatter research happens in the cold place is simple. The cold place stabilizes the material and minimizes its oscillation. The thing that makes the difference between matter and antimatter is the electric charge. The antimatter electron or positron has a positive charge and the antiproton has a negative charge. 

The antineutron spins oppositely to the neutron. Normally people say that the turn of the spin makes those antimatter particles. But then we must realize that the electrons and other particles like protons spin is 1/2 and that means they turn back and worth. So the spin is not the answer to the difference between matter and antimatter. 

The thing that makes antimatter interesting is its high energy capacity. When an antimatter particle touches its mirror-particle both of those things turn into energy. That reaction is called an annihilation reaction. The antimatter engine would be an excellent tool for travel inside the solar system and maybe to the stars. Antimatter is very expensive. 

Artists's impression of antimatter rocket. In visions all antimatter rockets are long. That keeps the engine and nuclear reactor away from the cabin and protects it against radiation. Also, the accelerator requires length so that it can accelerate particles enough. The system uses a nuclear fission reactor to start the antimatter system. But when annihilation starts the system can turn to use annihilation as an energy source and the nuclear fission reactor can shut down. 

The particle accelerators produce that thing. Antimatter is a very dangerous material. About a gram of that thing can destroy the entire Earth. Reseachers are made magnetic storages for antimatter antimatter particles hover in magnetic fields in a vacuum. That denies the antimatter particles touching the wall of the chamber. 

In the newest plans, the antimatter engine can make the antimatter by using a particle accelerator that gets energy from the nuclear reactors. The system shoots electrons through the thin gold layer that turns them into anti-electrons. Then those anti-electrons or positrons will be injected into a reaction chamber where they react with hydrogen or electrons. And that creates lots of energy. 

Researchers introduced many military applications of antimatter. The "Teller's bomb" the antimatter bomb would be the most horrifying weapon that man ever invented. The system uses antimatter as an explosive. Basically, Teller's bomb is the cathode ray that travels through the antimatter transformation process. Or. It's only the magnetic chamber where antimatter hovers. Then explosive breaks its shell. That thing makes it possible to create a cigarette-size nuclear bomb that destroys the entire city. 

But there are made plans about things called "limited Teller's bomb". The system is actually a bullet there is a magnetic chamber. The antiprotons or positrons hover in that chamber. That allows to creation of a handgun bullet that destroys the aircraft carrier.
