Would it be imperceptible? The storage rings on the spacecraft will hold the antimatter. "One particle is left over out of a billion, and this one particle out of a billion is everything we see in the Universe. Still a single bomb, it destroys the earth and you have plenty of time for popcorn while you wait. Antimatter weapons would be the most destructive and powerful in human history, so why dont they exist? During this interval, the pressure rises abruptly to a peak value and then decays exponentially over time. Collisions between these photons would have resulted in the production of particlesparticles which would eventually become stars, galaxies, and people. This calculation helps us in finding the pressure loads on objects. An antimatter weapon is a theoretically possible device using antimatter as a power source, a propellant, or an explosive for a weapon. The best answers are voted up and rise to the top, Not the answer you're looking for? Using the convention that 1 kiloton TNT equivalent = 4.1841012 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). Given a pair of explosives, one can produce 2 the shockwave output (this depends on the distance of measuring instruments) but the difference in direct metal cutting ability may be 4 higher for one type of metal and 7 higher for another type of metal.

Answer (1 of 6): Let's assume a gram of antihydrogen, which would release about 2 GeV per annihilation. They dont allow anything to shake their commitment to the Big Bang story, even the conclusion that our universe shouldnt exist if the Big Bang were true! [3], The kiloton and megaton of TNT equivalent have traditionally been used to describe the energy output, and hence the destructive power, of a nuclear weapon. Interaction with the blast wave can cause severe injuries (see injury severity score calculator) depending on the stand-off distance. Crash it into an iridium block. Professor Doser once estimated how muchit would cost to make antimatter in large amounts. For scenario 1, you'd probably be able to get by with even less just tens of grains per person, targeted at the brain would be enough to cause embolisms. Can we add matter and antimatter to the universe? On the subatomic level, this energy is manageable, but if one were to combine a gram of antimatter with a gram of matter, the result is an energy release comparable to the atomic explosion at . We must use a bigger bomb. A 10kg antimatter bomb would cause a gigantic 230 megaton explosion. We acknowledge Aboriginal and Torres Strait Islander peoples as the First Australians and Traditional Custodians of the lands where we live, learn, and work. 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. So each 2 kg antimatter bomb (as it annihilates with 1kg ordinary matter) would have a blast similar to the Tsar Bomba, the most powerful nuclear device ever detonated in the puny humans' history. [4], Alternative values for TNT equivalency can be calculated according to which property is being compared and when in the two detonation processes the values are measured. Professor Doser actually thinks matter might be the evil half of this equation, with antimatter being the "good guy". Would it be similarly anti-climactic? For a fragmenting munition where public access is possible, the TNT explosion radius, DDD, is: This distance is different for the bare explosives. 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. For a spherical blast wave, the change in pressure is: The above equation is known as the modified Friedlander equation, and it is used to calculate the change in pressure over time. It actually produces one about every one hour and fifteen minutes. Mathematically, the ratio of the weight of the explosives (W and W) is proportional to the ratio of the cube of range (R and R), i.e.
