- nickpinkstonVery cool! There's some wild ideas about antimatter capture in space via giant arrays of superconducting magnets trapping naturally occurring antimatter.Apparently, nanograms / micrograms is enough to create a "antimatter catalyzed" fission/fusion propulsion system with enormous specific impulse / efficacy.PDF: https://www.niac.usra.edu/files/studies/final_report/1071Bic...
- foobarbecueI don't get how they know they have exactly one in there. I mean they're measuring the magnetic field but how on earth do you make sufficiently precise measurements to detect a single particle!?!Edit: this is explained pretty extensively in the paper (https://cfp.physics.northwestern.edu/documents/2026OnePositr...). I'm gonna need to do some background reading though...
- fshExciting results. The electron's magnetic moment is probably the most precise standard model prediction, and Gabrielse's group has measured it with 13 digits of accuracy. The positron is predicted to have exactly the same magnetic moment, but this has not been measured since 1987. With the new trap, they should be able to finally match the electron's precision.

- bilsbieWhat happens if an anti proton hits a normal hydrogen atom?
- androiddrewI kind of want to know how they safely deal with its release (destruction)
- DoctorOetkerwhats up with all the comments making analogies with AI torture repository?One might measure the "amount of computation going on" as a proxy for consciousness, but "number of dissipative logic gates" can't be right since one can construct larger reversible circuits containing the same computation (and hence dissipation is a poor measure), although one could then use the total number of bits (including trash bits) as the measure.but I don't understand why particle physics?having all other comments (at the time of writing) be about consciousness of individual particles, seems to indicate these commenters specifically believe particle physics or antimatter to directly describe consciousness?Or is this some kind of "disinfo inoculation campaign" to render us immune to "sentient rights propaganda"?
- pizzafeelsrightof course the cyclotron going clockwise.
- snailshareDoes this hurt the positron?
- bozdemirThat's matter cruelty. We need more ethical ways to study those poor things. Does anyone know what happened after the experiment ? Did they finally let it go?
- lifeisstillgoodThe parents of the anti-matter particle then freeze time just as the containment is about to explode, allowing Picard and Geordi to wander around the facility looking for clues - until one scientists head slowly turns - they are also awake !!
- jimnotgymI hope they took precautions against the Camerlengo stealing it
- shireboyThe Ackbar Effect
- condour75It probably got Copenhagen syndrome
