Quoted: it's much muuuuuch worse than that! I don't remember the actual numbers but numbers like million and billion pop up when you start talking about the process. Very very very hard to make antimatter. View Quote @LowBeta Some hospitals have cyclotrons to make fluoride-18, which produces a positron when it decays. |

Quoted: Alpha (one of the CERN experiments) is capturing on the order of 50~100 at a time. When Fermilab was at peak antimatter production, it was making about 25x1010 (25E10) antiprotons/hour, 24/7/365. The largest quantity of antiprotons Fermilab stored was something like ~450E10. It took 6 particle accelerators to make and store the antiprotons, and a 7th (Tevatron) to use them. View Quote |

In HS physics long ago we calculated how much energy would be released converting 5 grams of matter (a US five cent piece, IIRC). It was equivalent to a good sized nuclear explosion.

Quoted: In high energy physics mode, antiprotons are relativistic, traveling at .999+ the speed of light. 8 to 980 GeV. Not really set up to measure something like gravity. The CERN antimatter has been cooled down to .012 degrees above absolute zero and is held in position with a laser. View Quote How can that low of a temperature be achieved? |

Quoted: Well, just a rough guess, but if they were making a ton of the stuff it could potentially end modern civilization. If they were making a kilogram of the stuff it could end a large city. If they were making a gram of the stuff it could take out CERN and leave a big crater. If they were making a milligram of the stuff it could do a lot of damage to CERN and kill some scientists. If they were making a microgram of the stuff it could maybe kill everyone in a room. How much are they making?

I'd think SpaceX might be cheap enough that you wouldn't need that. You will need a von Neumann-able process for making solar cells, which will power everything else. Build your antimatter factories, build your starwisps on up to generation ships---"Yeah, you're catching a ride on Hale-Bopp, all right."---and go go go. |

Quoted: You contain antimatter by keeping in very high vacuum and magnetically controlling its position. We used a ring about a km in diameter. https://www.ar15.com/media/mediaFiles/176296/6958346142_214b0bc3c3_o-2913069.jpg The only thing they're good for is to kaboom them and measure what kind of other particles fall out. They really do annihilate when they contact any normal matter. Star Trek got that right. View Quote In high school, my physics class took a field trip to Fermilab.

View Quote This is why we colonize Mercury and build a network of power sattelites. Once human civilization has cheap abundant solar energy we can do practically anything we want within the realm of physics as we currently understand it. That's going to take awhile though. Who knows what we will know in 500 years? |

Quoted: Piffle. I made several orders of magnitude more antiprotons than CERN ever will make of anti-hydrogen. Several world records, actually. If you took all the antimatter I made and blew it up you'd get on the order of a stick or three of dynamite's worth of kaboom. 100% nothingburger.

Quoted: Quoted: Quoted: Antimatter? meh, what could possibly go wrong? That was my reaction And I'm going to take your word on it. Literally. I learned something from wiki. In modern physics, antimatter is defined as matter composed of the antiparticles (or "partners") of the corresponding particles in "ordinary" matter, and can be thought of as matter with reversed charge, parity, and time, known as CPT reversal. Antimatter occurs in natural processes like cosmic ray collisions and some types of radioactive decay, but only a tiny fraction of these have successfully been bound together in experiments to form antiatoms. Minuscule numbers of antiparticles can be generated at particle accelerators; however, total artificial production has been only a few nanograms.[1] No macroscopic amount of antimatter has ever been assembled due to the extreme cost and difficulty of production and handling. In theory, a particle and its antiparticle (for example, a proton and an antiproton) have the same mass, but opposite electric charge, and other differences in quantum numbers. A collision between any particle and its anti-particle partner leads to their mutual annihilation, giving rise to various proportions of intense photons (gamma rays), neutrinos, and sometimes less-massive particle–antiparticle pairs. The majority of the total energy of annihilation emerges in the form of ionizing radiation. If surrounding matter is present, the energy content of this radiation will be absorbed and converted into other forms of energy, such as heat or light. The amount of energy released is usually proportional to the total mass of the collided matter and antimatter, in accordance with the notable mass–energy equivalence equation, E=mc2.[2] Antiparticles bind with each other to form antimatter, just as ordinary particles bind to form normal matter. For example, a positron (the antiparticle of the electron) and an antiproton (the antiparticle of the proton) can form an antihydrogen atom. The nuclei of antihelium have been artificially produced, albeit with difficulty, and are the most complex anti-nuclei so far observed.[3] Physical principles indicate that complex antimatter atomic nuclei are possible, as well as anti-atoms corresponding to the known chemical elements. There is strong evidence that the observable universe is composed almost entirely of ordinary matter, as opposed to an equal mixture of matter and antimatter.[4] This asymmetry of matter and antimatter in the visible universe is one of the great unsolved problems in physics.[5] The process by which this inequality between matter and antimatter particles developed is called baryogenesis.
