So 1 mg 18F-FDG will produce about ~10^15 times as much annihilation energy as a single anti-proton (these are just rough estimates to get a feel for the magnitudes involved). "So we actually need infrastructure like at CERN, accelerators that will produce enough energy locally in a very small spot to produce pairs of an antiproton and a proton.". You can maybe kill everyone with less antimatter if you settled for giving everyone cancer instead. The positron has the same mass as an electron but with a positive charge, rather than negative. What can I do with 100 grams of antimatter? - Quora "One particle is left over out of a billion, and this one particle out of a billion is everything we see in the Universe. Space Mechs or Tanks or Planes or Marines - Fighting in space without blowing up each other's starships. Con: You need a lotta bombs. $3.6567*10^{18}kJ*K^{-1} * 200K=7.31310^{20} kJ$. Note It is convention to use ton compared to short ton, net ton American or tonne (1000 kilogrammes.) Can antimatter projectiles work as disintegration weapons? This stops it from making contact with matter. I was planning on adding more to this response, but I think Serban covered it as well as I can for numbers #1 and #2. the algonquin club boston cookies that taste like mcdonaldland cookies 0 Comments 1 View 0 Likes. This form is part of the U.S. implementation of the Comprehensive Test Ban Treaty and is submitted voluntarily by mines that conduct blasts with over 300 short tons "TNT equivalent" of explosives. First, let's talk about blast waves. The reaction of 1 kg of antimatter with 1 kg of matter would produce 1.8 10 17 J (180 petajoules) of energy (by the mass-energy equivalence formula, E=mc 2), or the rough equivalent of 43 megatons of TNT - slightly less than the yield of the 27,000 kg Tsar Bomba, the largest thermonuclear weapon ever detonated. 7g divided 7 bn ways would equate to about the equivalent of 40 grams of TNT per person, something like a small hand grenade each. by Weaselmancer ( 533834 ) on Monday October 04, 2004 @04:06PM ( #10432675 ) The San Francisco Chronicle is reporting that the Air Force is actively pursuing antimatter weapons. Now, if we were sloppy, we would just pepper the land area of $148,300,000 km^2$, so about 1,236 MIEVs (Multiple Independently Targetable Entry Vehicles) with 100 2kg warheads each would do. Also your question only speaks about blowing up a planet completely, whereas my questions number 1 and 2 only speak about killing all humans and all animals respectively which is very different (your question very clearly states near the end "I dont just want to destroy all life on the surface, I want to reduce the entire planet to rubble so that very little remains"). Learn more about Stack Overflow the company, and our products. But why do so many Christians still claim that God used the Big Bang to create the universe, especially when this scientifically bankrupt speculation contradicts the Genesis creation account in so many ways?5 The Big Bang is, and always has been, unsupported speculation. The bottle is called a trap because thats what it does, it traps antimatter. Anti-matter Energy Calculator The opposite to Worldbuilding: World Destruction, Improving the copy in the close modal and post notices - 2023 edition, New blog post from our CEO Prashanth: Community is the future of AI. What could humans do to render the earth uninhabitable? The energy released by a hurricane per day during condensation. Comparing with nuclear weapons, this is about 50 kton TNT. In other words, beyond this distance, one can assume there would be fewer or no fragments flying. He says an alternative hypothesis is that we're living in a part of the Universe filled with matter but other parts might be full of antimatter. Ubuntu won't accept my choice of password. The shock wave is usually spherical or hemispherical in shape. The antimatter we produce collides with matter and gets annihilated without us even noticing. Crash it into an iridium block. $\begingroup$ For shooting it through the air: you need to have some kind of containment anyway and a single gram of antimatter-matter annihilation is like an atombomb going off so you dont need much. Michael Doser who works in the only factory making it describes thisreaction as "probably the most violent process you can think of because the full mass of the object disappears and transforms into energy". Is it possible to transform energy stored in anti-matter into coherent radiation? Small TNT explosions, especially in the open, don't tend to burn the carbon-particle and hydrocarbon products of the explosion. "Even in that hypothesis you'd still need a gram of antimatter, which would take 10 billion years to accumulate," Professor Doser says. Calculating a single RE factor for an explosive is, however, impossible. Unravelling this cosmic conundrum is what the researchers at CERN's Antimatter Factory are trying to do. $361,000,000 km^2$ to cover, you'd need another 3,009 MIEVs.

Thanks for contributing an answer to Physics Stack Exchange! If the null hypothesis is never really true, is there a point to using a statistical test without a priori power analysis? Let's estimate the safety distance for the detonation of bare exposed 0.5kg0.5~\mathrm{kg}0.5kg of TNT. Squared it is 89,875,517,900,000,000 or about 9.010 16. Electron + positron = 2 * gamma going opposite directions and having nearly the same energy of electron + positron mass-energies. No, the only way to be sure is to be thorough. It only takes a minute to sign up. Hence why I'm thinking they may have tried to say "Nope, 3,000m of Antimatter would really only be an explosion this big" as opposed to "Something as big as your hand would utterly level half of Rome" which is significantly smaller than 3,000m. Given how difficult it is to make antimatter, this is probably the only way could do so using antimatter within the next 100 years. Using the convention that 1 kiloton TNT equivalent = 4.18410 12 joules (or one trillion calories of energy), one half gram of antimatter reacting with one half gram of ordinary matter (one gram total) results in 21.5 kilotons-equivalent of energy (the same as the atomic bomb dropped on Nagasaki in 1945). Antimatter Fuel - Atomic Rockets Frank Close, a particle physicist at the University of Oxford, points out the time problem, too. Often, the responses are droll ones such as love, cocaine, cash money, computer ink, or even sex. What actually happens when an anti-matter projectile collides with matter? But antimatter is incredibly scarce, and scientists still dont know why. To study antimatter, you must prevent it from being annihilated . The ablative engine, which slowly vaporizes itself to produce thrust, could go as high as 5,000 seconds. The reality is that. You have antimatter containment capsule that only has to hold out for seconds at most when fired. It is a spherical or hemispherical-shaped wave that originates upon the detonation of explosives. TNT equivalent is a convention for expressing energy, typically used to describe the energy released in an explosion. Check out 477 similar physics calculators, Social Media Time Alternatives Calculator. So far, all the antimatter created in all the particle accelerators on Earth wouldn't be enough to boil a cup of water. Right now, antimatter - with a price tag of about $62.5 trillion per gram - is the most expensive substance on the Earth. I have no idea how to get that in an antimatter bomb, because of the fizzle problem noted above. 4. The explosive energy of a quantity of TNT of the. There are two surefire ways. 10 grams of antimatter will annihilate 10 g matter, which just produces 429.6 kT. Using PETN, engineers would need 1.0/1.66 (or 0.60) kg to obtain the same effects as 1kg of TNT. "You need 2,000 times more energy to make [anti-protons]," he says. This means that even if a supposed Big Bang could somehow create a universe, that universe would forever remain devoid of matter, unlike the actual universe in which we live. The previous answer covered the bases fairly well for options 1 and 3.
