The same process happens in the human body too, so we're all creating anti-electrons. If the Big Bang led to equal parts matter and antimatter forming, these probably would have then bumped into each other, obliterated one another, and then presumably exploded again. Such that: You can calculate the blast radius or stand-off distance using the Hopkinson-Cranz scaling law. Now they're back in Kyiv, Baby with bowel obstruction died after hospital's failures, coroner finds, NT Chief Minister apologises to outgoing police commissioner over retirement settlement comments, Nouma is an island paradise but for the next year you're not allowed to swim, Live: Celebrities arrive at the Met Gala for fashion's biggest night, Texas college baseball player accidentally shot during game, Three firefighters rushed to hospital, one critical, after factory fire south of Brisbane, Live: Reserve Bank tipped to leave interest rates on hold for a second month, ASX to open lower. The sub-atomic particles of matter have the opposite properties of antimatter. Here they create and capture this bizarre anti-stuff. This sounds like a good thing at first, but it just means that antimatter weapons could be seen as more politically acceptable, and therefore more likely to be used in warfare. Actually, its even worse than that, because matter and antimatter particles annihilate one another whenever they come into contact! For Starship, using B9 and later, how will separation work if the Hydrualic Power Units are no longer needed for the TVC System? NASA - New and Improved Antimatter Spaceship for Mars Missions Instead of wasting 1E28 joules in an antimatter explosion on the surface of Earth, how about a nice 1E20 J bomb set off in a carefully drilled hole inside 10 Hygiea -- wait a few months and let gravity do most of the heavy lifting (or falling in this case) when 10 Hygiea impacts the Earth. Making 1 gram of antimatter would require approximately 25 million billion (10 15) kilowatt-hours of energy and cost over a million billion US dollars. It doesn't sound like it should be real, but "it does exist", says Professor Doser,a physicist who studies the properties of antimatterat CERN,the European Council for Nuclear Research. Let's estimate the safety distance for the detonation of bare exposed 0.5kg0.5~\mathrm{kg}0.5kg of TNT. Generating points along line with specifying the origin of point generation in QGIS. Check the revision history; if it's appropriate, feel free to roll back my roll back! Antimatter: how the worlds most expensive and explosive substance is made, Catch up with The Loop, your quick wrap of this morning's news. But that would miss all the boats, planes and submarines crowding their primitive buoyancy based transportation lanes. The relative effectiveness factor (RE factor) relates an explosive's demolition power to that of TNT, in units of the TNT equivalent/kg (TNTe/kg). The time of interaction is very short. Explosive Yield of a Photon Torpedo. - ST-v-SW.Net This calculator and the accompanying article will explain what explosion radius is and how to calculate blast radius. What if I had 1 anti-hydrogen atom or enough antimatter that's equal in "weight" to a hydrogen atom? 1 kg of antimatter = 53 megaton yield, 4000 kg antimatter = 212 billion ton TNT, $3.6567*10^{18}kJ*K^{-1} * 200K=7.31310^{20} kJ$. 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. Likewise, the antimatter counterpart to a proton is the anti-proton which has the same mass as a proton but with a negative charge.
