The LHC created Antihyperhelium-4.

"ALICE scientists at the LHC have detected evidence of antihyperhelium-4, marking the first observation of this antimatter hypernucleus. It is also the heaviest antimatter hypernucleus discovered at the LHC, offering valuable insight into how matter formed after the Big Bang.

The LHC made a new breakthrough in antimatter research. That collider created the heaviest known antimatter particle, The Antihyperhelium-4. That atom is the most interesting atomic particle in the world. The antimatter is a mirror of the material. The problem with antimatter is that when it touches the material both participants of the collision turn into wave movement in a reaction called: annihilation. 

The energy load of antimatter annihilation is so high, that one gram of antimatter can turn the Earth into a molecular cloud. That energy load makes antimatter research dangerous. But the fact is that. The magic gram of antimatter can give enough push to send a 1000 kg spaceship to Alpha Centauri. 

When researchers talk about things like antigravity and antimatter, they mean that they will use antimatter as an energy source for those systems. Those systems require very high energy levels that can create the energy level that can create gravitational waves. Antimatter is one of the most promising energy sources for those futuristic systems. The antimatter is otherwise like regular material. Gravity and other fundamental forces affect antimatter the same way they affect gravity. That means antigravity is not the effect or feature of antimatter itself. 

The Antihyperhelium-4 proves that antimatter can form similar particles as regular material. That means it's possible to create larger and easier-to-handle antimatter particles. 

Could primordial black holes explain the asymmetry in material-antimatter particle pairs? 

Is it possible that the annihilation in the early or young universe formed so-called primordial black holes? And could those black holes explain why there seems to be only material in the universe? When high-energy reactions form the primordial black holes those objects' high-power gravitational fields can form a situation where the antimatter and material pairs will separate. If those theoretical primordial black holes pulled more antimatter than matter inside them. 

That formed the material and universe as we know them. The Schwinger effect formed as much matter and antimatter. So. There was some force. That pulled those particles too far away from each other. And maybe that thing was a theoretical primordial black hole.  

The question is how there is only material in the universe. In "normal material". The protons are positive. And the electrons are negative. The quarks and other elementary particles like bosons have antiquark and antiboson pairs. Those particle pairs act like other particle-antiparticle pairs. 

In antimatter. The antiproton is negative and positron or anti-electron electricity is positive particle. That means those particles are mirrors of the regular material particles. 

Sometimes annihilation is introduced as the quantum electric arc that forms when oppositely polar particles touch each other. The annihilation forms when those particles like positron and electron quantum fields unite. And that forms a similar situation when somebody connects the battery's plus and minus poles together. 

The Schwinger effect (wave-particle duality)  forms particle-antiparticle pairs. And that thing means. That there should be as much antimatter in the universe as matter. The problem is that for some reason the symmetry of the particles was disturbed. And that formed a situation in which there was less antimatter than material. And in that annihilation, the antimatter lost. Or we certainly hope so. 

But sometimes people think that material-antimatter asymmetry is caused by those high-energy reactions forming so-called primordial black holes. When high-energy reactions push material it's possible that the high-energy annihilation can form black holes. The idea is that the antimatter is lost in those primordial black holes. Or maybe somewhere in the depths of the universe are stars or even galaxies that are formed of antimatter? That is one very interesting thing that we should research.
