Scientists do this all the time in labs.
There's no antimatter in the universe, but you constantly hear about scientists doing experiments with antimatter. Where do they get antimatter if it doesn't exist?
Simple: the create it out of thin air.
Think of it as a simple math equation. 1 + -1 = 0.
If you have a positive something and a negative something, and they combine, they annihilate each other and become nothing. But it just so happens you can reverse this and turn nothing into a positive something and a negative something (matter and antimatter).
Scientists who make antimatter do it by creating something from nothing then stripping the antimatter away from the matter that's created.
Something comes from nothing all the time, actually. Throughout the entire universe, even in your own hand, particles are popping into existence from nothing.
But the universe doesn't explode because things pop into existence in positive and negative pairs, and the pairs quickly collide with each other and annihilate. So they appear only for a brief moment then go away.
There's an experiment called the Dynamic Casimir Effect. Photons and antiphotons* also pop into existence, and you can strip the photon away from its pair and they won't be able to annihilate each other, thus, creating light from nothing. When the Dynamic Casimir Effect was first performed, it began to emit infrared light from nothing.
Something comes from nothing in labs all the time.
* Matter and antimatter behave differently, but photons and antiphotons are exactly the same, so some would argue antiphotons don't exist, but that's just semantics.

Yes. Nothing can come from something, and the reverse is also true. |

From your point of view they may be appearing and reappearing, but it could be teleportation. No matter which it is we definitely need to go deeper, this might be useful one day either to our understanding of physics or the technology we use for transportation, and there's also the best chance that it will be both...

i believe you can create something from nothing as well your this post coming from your brain is proof of that

but doesnt that mean we can also be erased from existence from atomic manipulation in the future

@qd
No, it is not teleportation. There's no reason to even think it is. Antimatter's future use would probably be in engines, weapons, and powerplants.
Antimatter would be the most efficient fuel in the universe. When antimatter collides with matter, you get a 100% conversion of antimatter into energy.
One gram of antimatter would provide 90 terajoules of energy. Comparatively, the atomic bomb dropped on Hiroshima produced 60 terajoules.
So literally a teaspoon of this would destroy a city.
@lagio
I said that. Photons have no charge so a photon and an antiphoton are identical.
@popom
If you could create enough antimatter to completely annihilate the earth, the energy released might even be enough to destroy the galaxy.
That's 53,673,659,300,000,000,000,000,000,000,000,000,000,000 petajoules of energy, which the largest atomic bomb ever dropped only produced 210 petajoules.
