Why This Stuff Costs $2700 Trillion Per Gram - Antimatter at CERN

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 Dianna Cowern Editor: Levi Butner Research & Writing: Sophia Chen & Dianna & Imogen AshfordSources: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 year2. This is about 1e15*1.67e-27kg = 1.67 nanogram per year3. 1 gram of antiprotons has an energy (E=mc^2) of 9e13 Joule4. The efficiency of the antiproton production process is 1e-9, so you need a billion times more energy: 9e22 Joule5. The cost of power for CERN is 1kWh = 3.6e6 Joule = 0.1 euro6. So that would make 0.1/3.6e6*9e22 = 2.5e15 euro7. And it would take CERN 6e8 years (1999) - you can see the nuke cityMass of Fish: "Contribution of Fish to the Marine Inorganic Carbon Cycle" Dirac’s attitude about the positive solution to his equation Dave’s Essay: Questions at CERN Creating Antihidrogen:
