It’s the rarest, most expensive, and potentially the most dangerous material on earth. Scientists don’t know why this material is so rare. Anti-atoms took 72 years after we discovered antimatter to make. Why? Thanks to CERN, Elise Wursten, Loïc Bommersbach and Sarah Charley http://physicsgirl.org/ http://twitter.com/thephysicsgirl http://facebook.com/thephysicsgirl http://instagram.com/thephysicsgirl Creator/Host: Dianna Cowern Editor: Levi Butner Research & Writing: Sophia Chen & Dianna & Imogen Ashford Sources: Current estimate of Antimatter, courtesy of Elise: Stefan Ulmer made a back-of-the-envelope calculation based on energy and power consumption. The explanation goes as follows: 1. CERN produces 3e7 antiprotons per AD cycle or about 1e15 per year 2. This is about 1e15*1.67e-27kg = 1.67 nanogram per year 3. 1 gram of antiprotons has an energy (E=mc^2) of 9e13 Joule 4. The efficiency of the antiproton production process is 1e-9, so you need a billion times more energy: 9e22 Joule 5. The cost of power for CERN is 1kWh = 3.6e6 Joule = 0.1 euro 6. So that would make 0.1/3.6e6*9e22 = 2.5e15 euro 7. And it would take CERN 6e8 years https://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19990110316.pdf (1999) https://nuclearsecrecy.com/nukemap/ - you can see the nuke city Mass of Fish: "Contribution of Fish to the Marine Inorganic Carbon Cycle" http://rsmas.miami.edu/groups/grosell/PDFs/2009%20Wilson%20et%20al.pdf https://web.archive.org/web/20120105085146/http://public.web.cern.ch/public/en/spotlight/SpotlightAandD-en.html Dirac’s attitude about the positive solution to his equation https://www.newscientist.com/article/dn17111-how-dirac-predicted-antimatter/ Dave’s Essay: http://multimidia.ufrgs.br/conteudo/frontdaciencia/dirac%20antimatter%20paper.pdf Questions at CERN https://public-archive.web.cern.ch/en/LHC/WhyLHC-en.html Creating Antihidrogen: https://home.cern/science/physics/antimatter/storing-antihydrogen https://public-archive.web.cern.ch/en/LHC/WhyLHC-en.html
