If containment was to fail, it the total energy released would have been approximately 2.766 * 10 ^ -8 J, so it wasn't particularly dangerous

What is that in firecrackers?
Gemini says a firecracker releases 150 J, so yeah not a lot.

It's a fraction of the energy released when an unlit fire cracker is dropped an inch. Basically unmeasurable

It was on the radio here (I live on its route)- the ‚receiving’ physicist said it would be way less than what we catch anyway from daily cosmic radiation.

For 92 protons? So 3*10^-10 J per proton?
For a tiny number, that is still insanely high...

Totally sounded like Star Trek. LOL. I imagined Mr. Scott yelling something about the transporters not being able to lock onto the antimatter.

From a layman's point of view antimatter seems like an ideal spacecraft fuel. It's as energy dense as E = mc^2 allows, and if you have infrastructure to make it, the only input you need to produce it is electricity.
Being able to transport it seems like an important piece of that puzzle.
Production and storage would need to be scaled by many orders of magnitude, but that's merely an engineering problem...right?

The confinement scheme used here is likely a Penning Trap. Such devices are limited in the amount of antimatter they can store by the Brillouin limit. The energy stored will be no more than the magnetic energy of the field of the trap, and so much less than the explosive yield of a mass of TNT (say) equal to the mass of the trap.

I suppose at least it will kill you faster than your neurons can communicate so you wouldn't even notice.

Don't you have that problem with any energy-dense fuel? It's just that it doesn get more dense than that, so you can be very space and weight efficient.
It's like everybody saying that a hydrogen car is a rolling bomb because of the energy stored in the hydrogen. Well, sure, but gasonline has just as much energy stored. Which is the whole point of fuel. To store energy. It's not like you are bringing 100x as much energy with you just because it's hydrogen. So that doesn't make an ICE car any less of a bomb...

If you're on a spacecraft you're sitting on a tank of rocket fuel anyway. It's the same problem, just slightly less total.

From a layman's point of view, I'm more interested in antimatter's potential as a weapon.
Not necessarily because I want to use it, but because I have a vague idea of what it's capable of, and what that would mean in the hands of certain groups capable of producing it.
pfdietz an hour ago
The big advantage of nuclear weapons is they are very cheap per unit of energy yield. Bang for the buck, if you will.
Antimatter production is so inefficient that they will be much more expensive per unit energy yield.

Very tough engineering problem. Amount transported is 92 atoms. A mole (1 gram) of anti-hydrogen is 6.23x10^23 atoms.
wiredfool 3 hours ago
When I visited CERN, they mentioned that there were some large number of protons in the ring at a time, and the runs would last a significant amount of wall clock time. (Don’t remember the exact numbers, but I think it was like 10^19 atoms of H, and days of wall clock)
The upshot was, it was likely that less than a mol of hydrogen had been run through the ring.

Not familiar with the subject so genuine question. HOW would antimatter be used as fuel? There is energy released in matter antimatter annihilation, but where would the force to move a spacecraft come from?
jjmarr 2 hours ago
> Various antiproton-powered rocket systems have been proposed. All of which rely on the particles released to supply direct thrust or to heat a working fluid by interparticle collisions or by heating a solid core first [14]. There is also the possibility to use the heated working fluid to generate electricity for electric propulsion systems [14].
> Following Fig. 9, beam core and plasma core configurations can produce direct thrust by directing the charged particles produced into an exhaust beam using a magnetic nozzle. Gas core systems use the energy released from the reaction to heat a gas that is exhausted for thrust. Finally, solid core configuration heats a metal core like Tungsten that acts as a heat exchanger to a propellant that is then exhausted from a regular nozzle.
Not the same paper, but goes into more detail.

I am curious about how much energy needs to be expanded to contain the anti-matter. Say it the matter/anti-matter is to be used for propulsion/energy generation can we reach a threshold were we are actually energy positive

“Antimatter in a truck” is great headline material, but the actual advance is portable precision instrumentation.
CERN can make/store the antiprotons, but not measure them as cleanly as they want because the facility itself introduces tiny magnetic fluctuations. So this is really a story about moving the sample to a quieter lab, not moving toward sci-fi antimatter batteries... for now

Yeah, it's really impressive to me that they can make antiparticles, put them in a container, count them, transport them and count them again.

Nonetheless, "moving antimatter by truck" is pretty SF. More grounded than epic space opera, but stillvery cool.

What would a universe with equal amounts of matter and antimatter look like?
a-priori 3 hours ago
It would develop into "regions" of space that are entirely matter and others that are entirely antimatter. The boundaries between them would glow as stray particles drift between the regions and are annihilated by contact with the opposing particles.
The fact that we don't see these glowing boundaries in space is evidence that there are not antimatter regions and that the visible universe is almost entirely composed of matter.

It would depend on how it's distributed. If it's very homogeneous, totally anihilated. If there are galaxies of matter and galaxies of antimatter, more or less like us with a bit more background radiation.

elil17 3 hours ago
Yes, only anti-truckers can haul anti-matter since normal CDLs only let you transport ordinary matter. You have to be very careful not to let the anti-trucker go to a ordinary truck stop because things really go down if they run into a ordinary trucker.
