mildseason comments on Scientists trap and tame a single particle of antimatter for months

A positron gets created by radioactive decay. Certainly the process to make an appropriate isotope (Sodium 22) is not trivial but the creation anti-matter will just happen.

Capturing it and storing it is the hard part which the team proved they can do. As they were working with a single positron and have developed the procedure for capturing one there is no reason to keep it for further experiments.

so again. if the energy used to capture is trivial to the energy used to contain. I want to know that. What im really looking for is the practicality of long term storage.

Ah sorry i get you! Yeah like how long could we go? Indefinitely?

Looking at the photo the equipment does seem quite large, it takes up the whole room. Can say for sure they don't have the funding to dedicate that much equipment to a static experiment.

Do agree with you though. Would be interesting to see the numbers for long term storage.

yeah and you might be on to something. they might already have ideas to reduce the size or complexity and might follow up using a different design. I have been involved in a lot of projects with a large and ugly prototype to prove some stuff and then greater effort is put into design once they know the idea works.

Aw yeah for sure they could make it more compact! Would love to see it. If we could actually make meaningful quantities of anti-matter. Could we use it for power? What would transport look like? Anti-matter is one of my favourite subjects lol

Once we unlock antimatter-fueled propulsion we could send a probe to the Proxima Centauri system.

If we try sending one now, even if it escapes the sun's gravity well, it would easily be passed by a future probe if antimatter propulsion is invented within the next century or so.

Once the probe reaches the system, it would take a little over a decade for a radio signal to reach us. So it would need some built-in automation to run research missions because the latency is just too high for remote control from Earth. Unless some sort of quantum entanglement technology enables instantaneous communication, but that might just be scifi...
