I have no idea what you're talking about. This one bullet would be equivalent to 378 grams of TNT, which is more powerful than a modern grenade. What could humans do to render the earth uninhabitable? So not only would they be more powerful than nukes, but also more likely to be used on people. Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Collisions between these photons would have resulted in the production of particlesparticles which would eventually become stars, galaxies, and people. At least a trillion tons, probably an order of magnitude or so more when you account for noncentral location and dissipation loss. CAUTION There are many hypothetical antimatter weapons, the most well known of which is the antimatter bomb. The same technology could theoretically be used to make very small and possibly "fission-free" (very low nuclear fallout) weapons (see pure fusion weapon). "If we don't find a difference between matter and antimatter, then that's going to be the only remaining explanation," Professor Doser says. This result eliminates one possible loophole that Big Bang cosmologists were hoping to exploit in an attempt to solve this longstanding problem with their model.

To study antimatter, you must prevent it from being annihilated . Con: You need a lotta bombs. All of the other answers here are super overkill for this. So in this Big Bang scenario, particles and antiparticles would have been coming into existence and then annihilating one another in equal measure. Would it just be a stupidly bright flash? "Even in that hypothesis you'd still need a gram of antimatter, which would take 10 billion years to accumulate," Professor Doser says. Those made at CERN amount to about 1 nanogram. He also rips off an arm to use as a sword. Small TNT explosions, especially in the open, don't tend to burn the carbon-particle and hydrocarbon products of the explosion. Something like this would probably be your optimal (in terms of parsimonious use of anti matter, anyway) approach for #1 and #2. And if you're concerned that this work doesn't warrant fooling around with such a violently explosive anti-substance, Professor Doser says there's no need to worry. You'll need a fair bit of antimatter, um, let's see 1 Mt is $4.1\times10^{15} J$ so the Tsar Bomba (in the tested config) at $42MT = 1.72 \times10^{17} J$ The total solar irradiance energy received by Earth in the upper atmosphere per hour. What Is Antimatter? ", "Beirut Blast: How does yield of 2,750 tonnes of ammonium nitrate compare against Halifax explosion, Hiroshima bombing? In other words, antimatter planets, antimatter stars or antimatter galaxies could be a thing. Squared it is 89,875,517,900,000,000 or about 9.010 16. $> 10^{32}J$. You get high-energy (~100 MeV) gammas, medium-energy (e.g., 511 keV) gammas, pions, muons, and neutrinos. And yet, there is very little antimatter in the universeso its been a known problem for many years. Unconventional Rocket Drives - Antimatter Propulsion 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. Calculating a single RE factor for an explosive is, however, impossible. 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. For a period of time after the Big Bang there was only energy. Are Neutrons and anti-Neutrons attracted to each other over distance? So far, all the antimatter created in all the particle accelerators on Earth wouldn't be enough to boil a cup of water. Some of the radiation will doubtless cause fission or transmutation - a nucleus hit by an anti-proton is likely to at least lose a nucleon, and the mesons also happily react with nuclei. For a 10 km dinosaur killer asteroid, 1 kg of antimatter should be sufficient retarget the asteroid -- actually quite a bit less would actually be needed because there are quite a few near earth objects that would need only a tiny orbital deflection to serve the purpose, the largest of these earth crossers, 1866 Sysyphusone of these objects happens to fit the bill as it is probably over 8 km diameter (close enough for our imagination) and currently scheduled to pass about 17 million km from the earth on Nov 24, 2071. The approximate radiant heat energy released during 3-phase, 600V, 100kA, Conventional bombs yield from less than one ton to, A real 0.454-kiloton-of-TNT (1.90TJ) charge at. From some rough calculations with 10g of anti hydrogen, I came out at roughly a gigatonne of TNT's worth of energy - 1.2x10^22J. Still a big bang. You can also convert entire earth into energy but you have to look for antimatter earth to do it. Generating points along line with specifying the origin of point generation in QGIS. the algonquin club boston cookies that taste like mcdonaldland cookies 0 Comments 1 View 0 Likes. Some humans would probably survive this, though. Use MathJax to format equations. Would it be imperceptible? Different types of antimatter require different types of traps. Physics Stack Exchange is a question and answer site for active researchers, academics and students of physics. Or a kilogram? [9], But, even on this basis, comparing the actual energy yields of a large nuclear device and an explosion of TNT can be slightly inaccurate. In John Barnes' excellent Thousand Cultures series, the ultimate nasty weapon is the teleportation of antimatter into the atmosphere as a very fine dust spread over a large volume. But, taking the statement as accurate (and the source appears to be of generally high quality to me). One in every million collisions creates a proton-antiproton pair. 1 gram of TNT = 2930.76 joules. Approximately 10 grams of antiprotons would be enough fuel to send a manned spacecraft to Mars in one month. "Bananas are a perfect unit for antimatter production. Everyone knows biking is fantastic, but only this Car vs. Bike Calculator turns biking hours into trees! Antimatter annihilation from anti-hydrogen is surprisingly messy: it will not be pure gamma rays. But because this claim is not based on any empirical science, its never been anything more than pure speculation. That should be a pure gamma output initially, but I'm curious as to what would happen to the atmosphere - what will happen to that much energy, will fission happen and how much life will survive? Shortly after the supposed Big Bang, the universe would have been filled with extremely energetic photons. Photons are bundles of electromagnetic energy. Browse other questions tagged, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site. The approximate total yield of the super-eruption of the. A blast wave unleashes a large amount of energy that causes changes in pressure and temperature along its path. [2], The "megaton (of TNT equivalent)" is a unit of energy equal to 4.184 petajoules (4.1841015J). WAY too much. A typical blast wave has a high-pressure jump, which denotes the wavefront. The team can create thousands of antihydrogen atoms in only a second but the trap barely catches any. Check out 477 similar physics calculators, Social Media Time Alternatives Calculator. These complications have been sidestepped by convention. Antimatter is one of the costliest materials in the world. Antimatter is one of the costliest materials in the world. Asking for help, clarification, or responding to other answers. Similarly, you can estimate the blast radius for c4 explosives too. With about 100,000 ships out there, that's a lot of survivors. What differentiates living as mere roommates from living in a marriage-like relationship? I definitely think #1 is overkill in his answer though. 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. Given how difficult it is to make antimatter, this is probably the only way could do so using antimatter within the next 100 years. Interaction with the blast wave can cause severe injuries (see injury severity score calculator) depending on the stand-off distance. For example, if a timber-cutting formula calls for a charge of 1kg of TNT, then based on octanitrocubane's RE factor of 2.38, it would take only 1.0/2.38 (or 0.42) kg of it to do the same job. And the final is that it might help us solve a fairly enormous cosmic conundrum: why the material universe exists. The antimatter bomb is something any country rich enough could potentially make but its so expensive no country has put in the effort. The best answers are voted up and rise to the top, Not the answer you're looking for? Or would it be more like a conventional ~50kg artillery shell? Converts antimatter to energy in joules. A minor scale definition: am I missing something? The recipe they use at CERN's Antimatter Factory to achieve this feat is: 1. The energy contained in one megaton of TNT (4.2PJ) is enough to power the average American household for 103,000 years. If you really need to do this on the cheap, a 400 km asteroid is really quite a bit of overkill and a 100 km asteroid is probably enough to kill all animal life big enough to be interesting to most people although it may not completely sterilize the earth, and your only need 1 metric ton to target earth. As we learned in real estate, location, location, location. But even this is insanely expensive for only one bullet. That's5 thousand trillion euros. This law states that two identical explosives produce similar blast waves but have different sizes, given the conditions, geometry, and scaled distances are identical.
