Answer (1 of 6): Let's assume a gram of antihydrogen, which would release about 2 GeV per annihilation. With ANFO or ammonium nitrate, they would require 1.0/0.74 (or 1.35) kg or 1.0/0.32 (or 3.125) kg, respectively. Where can I find a clear diagram of the SPECK algorithm?

The total energy output of the Sun per second. Except the isochoric heat capacity of earth atmosphere is $C_v=.717kJ*kg^{-1}*K^{-1}$. Theviolence of an antimatterreactionwas clearly demonstrated when a tiny pinch of the stuff exploded over Vatican City in the fictional Dan Brown epic, Angels and Demons.

The positron has the same mass as an electron but with a positive charge, rather than negative. The basic principleis that so much energy is concentrated at a single point that it creates mass the mass of matter.

Why is this antimatter issue a big problem for the Big Bang? The bottle is called a trap because thats what it does, it traps antimatter. It basically all reacts at once release an enormous amount if IR -- enough to melt any rock within sight -- followed by a blast wave. There are two surefire ways. achieving the specified result. We could make this happen if we work at it. This is one of the more common types of "TNT equivalence" and is the one used on USGS form 9-4040A. 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. Just one 10 thousandths of a gram of antimatter could send a spaceship to Mars in only 45 days. Would a kilogram of antimatter be equal to a 500kg bomb of conventional Heavy Exosives? Unconventional Rocket Drives - Antimatter Propulsion $361,000,000 km^2$ to cover, you'd need another 3,009 MIEVs. NASA have actually started planning to use antimatter spaceships to go to space. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. Unlike Big Bang speculation, these measurements, which are testable and repeatable, were real science. Antimatter is one of the costliest materials in the world. Air Force Researching Antimatter Weapons - Slashdot The fictional bomb works by touching 1 gram of matter to 1 gram of antimatter a substance made of sub-atomic particles with properties opposite those of normal matter particles causing. Antimatter weapon - Wikipedia Shock waves which is equivalent to "If we don't find a difference between matter and antimatter, then that's going to be the only remaining explanation," Professor Doser says. Scientists estimate creating and storing a gram of antimatter would cost in excess of a million billion dollars and require about 25 million billion kilowatt-hours of energy. Let's shoot to heat up the atmosphere by 200K; there's no way anyone's surviving that. However, the mean free path is so short at ambient pressure that they will react before going far (doing it in the upper atmosphere might produce a much larger and fuzzier fireball). There is no nuclear bomb that comes close to the power this bomb would have. What Is Antimatter? For Starship, using B9 and later, how will separation work if the Hydrualic Power Units are no longer needed for the TVC System? You bet. Back To Anycalculator.com Language links are at the top of the page across from the title. [7][8], An antimatter weapon is a part of the plot of the Dan Brown book Angels & Demons and its film adaptation, where it is used in a plot to blow up the Vatican City.[9][5]. The reality is that.

Check out 477 similar physics calculators, Social Media Time Alternatives Calculator. But antimatter is incredibly scarce, and scientists still dont know why. Current technology only allows us to store small amounts of antimatter in each Penning trap. Would matter-antimatter annihilation create a fireball or not? But because this claim is not based on any empirical science, its never been anything more than pure speculation. The NIAC is currently researching antimatter powered spaceships, and according to NASA it looks promising. So if correct the answer would answer question number 3, but questions number 1 and 2 are left unanswered. By Snell's law, determine the incident angle by using our angle of incidence calculator. 1 gram of TNT = 2930.76 joules. Divide the energy put out by this annihilation and we get $\Delta K = 14000$. The storage rings on the spacecraft will hold the antimatter. 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. ", "Beirut Blast: How does yield of 2,750 tonnes of ammonium nitrate compare against Halifax explosion, Hiroshima bombing? Why are players required to record the moves in World Championship Classical games? Collisions between these photons would have resulted in the production of particlesparticles which would eventually become stars, galaxies, and people. The best answers are voted up and rise to the top, Not the answer you're looking for? Something less than 7g to kill every human. "One 100th of a nanogram [of antimatter]costs as much as one kilogram of gold," he says. 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).
