Not sure why, but I found it amusing when they said that the antimatter "reached speeds of over 40 km/hour." Not sure what the speeds are at the point of its creation (there are knowledgeable folks on here who will know, I'm sure), but that must seem sloooooow in comparison.

The anti proton was very fast, but it needs to capture a positron to become an antimatter hydrogen atom. This happens after the anti proton was slowed down.

The point was that the van driving around with the containment device reached 40mph and this establishes that the containment device can handle a bit of rattling around They only had regular Protons in it for this test though. The point was to see if the Protons were still there after the 40 mph journey in a van

"We accelerated the antimatter to speeds of over 40 km/h!" "Good lord, using what technology?" "A DAF LF 180." Although i have no idea what actual make or model they used - i was appalled to see that it was not stated in the materials and methods section of the paper. There's a photo in a news piece showing it's a small rigid-sided lorry: https://home.cern/news/news/experiments/base-experiment-takes-big-step-towards-portable-antimatter https://home.cern/news/news/experiments/base-experiment-take...

> Not sure what the speeds are at the point of its creation That will be the speed of light for you. Not exactly the speed of light, but 0.999... with a few 9's.
