The apparatus would need to immediately separate the two to prevent an extremely large explosion. right. im sure the physists working on this project know that

right. im sure the physists working on this project know that, but im curious how much of a risk 100,000 matter/anti-matter pairs would make... i guess not much?
- grozzle 5y ago200000 hydrogen atoms has a mass of 201600 atomic mass units (about three haemoglobin molecules), which by e=mc² is about 188 TeV (tera electron volts), which is about 30 microJoules, or about 2% of the energy needed to register a key press on a mechanical keyboard.
- andrekandre 5y agothats amazingly cool way to put it, thanks ^^
- grozzle 5y ago(can't edit first comment, sorry) 1kg of mass to energy (assuming every single particle met a corresponding antiparticle) would release a little over half the energy of the Krakatoa volcano eruption, similar to a 21 megaton bomb, so around the upper end of fusion bombs. Helium is about 99.5% the mass of the hydrogen that goes into it, so I guess those big fusion bombs must produce about 200kg of helium?
- andrekandre 5y agowow interesting, when you say "upper end" it means the effeciency of matter → energy conversion is at the upper end of fusion, or 1kg of anti-matter would have the same power of an upper end fusion? either way super cool
- grozzle 5y agoI meant that 21 megatons is big enough to be among what the USA and USSR would have called their biggest H-bombs. (megaton, to be clear, is not a measure of mass when talking about bombs, it's a measure of energy released - a 1 megaton bomb is equivalent to the energy released by a million tons of TNT, if such a volume could be detonated)
