How did they know at any given point that it was still there? Wouldn’t they have to interact with it to be sure, causing an explosion and annihilating it? The explosion would be incredibly small with just one particle. Is the lack of explosion their only evidence that they had contained it? I’m stumped as to what it actually means to have one particle like this. How can you even know what temperature it is without interacting with it? And how do you interact with it without destroying it?

Your move antimatter

So it's potty trained and can do tricks now?

-"Free Anti Matt Er!"

I wonder if it likes one scientist over another scientist

This is actually really exciting! I fucking love anti-matter, always been fascinated by it.

If anti-matter can exist, why is our universe made of matter? This is the Baryon Asymmetry question that this research seeks to answer. The team has proven they can isolate a single positron. The next step is to measure it to as much accuracy as they have with the electron. Perhaps they will find differences!

Summer '25 CERN showed that anti-matter baryons (protons, neutrons, etc) decay differently - link. So there's a good chance they might find something!

Would love to actually see anti-matter but that's a long way off. Really hope anti-matter likes to stick together and we could actually build atoms out of it. Would be crazy to study the properties of anti-water! Maybe that's just science fiction. In any case, very excited for the coming research!

how did this get past the ethics committee

I wonder what they called it,since they tamed it.

I'm thinking Anton if it's a boy particle, Antonia if it's a girl, and Matty if it's nonbinary.

Perhaps Antti (Niemi) if it's Finnish 🤷🏻

Poor particle did nothing bad

Not gonna be impressed until they teach it to fetch.

If movies have taught me anything, that particle isn’t tame. It’s just waiting for it’s moment.

Antimatter matters!

Did they ask for consent?
