Angels and Demons Anti-matter explosion: Is is realistic? - General

[QUOTE=redonkulous;16488157]I actually do know a thing or two about this stuff. Antimatter is the most explosive thing we can think of of, and theoretically it would be impossible to be more explosive but we know so little about the universe that I'm not sure if that's true. The LHC would not take billions of years to make a gram, I don't know how long it would be but the fastest thing we had before it would take about a hundred or two. And to the above guy, it creates pure energy when it explodes. Only when we make matter do we create an equal amount of antimatter.[/QUOTE] It generally releases energy in the form of gamma radiation, or occasionally in the form of heavy exotic particles. Energy can exist as mass as well, remember.

Why the hell is there more than 1 explosion.

[QUOTE=Xenos;16488044]Anti matter and matter have never made contact because when the reaction occurs, it creates more anti-matter. Therefor, if it were ever to mix, you wouldn't be alive to know about it.[/QUOTE] No that's strange matter. [QUOTE=Xenos;16488207]Anti-matter is made in the sun and stays in the sun. Anti-matter is neutralized inside the sun when it interacts with regular matter.[/QUOTE] No the sun uses nuclear fusion.

[QUOTE=McSanchez;16488330]No the sun uses nuclear fusion.[/QUOTE] Yes, it does, but a by product of it's processis is antimatter. Don't believe me? [url]http://www.nasa.gov/centers/goddard/news/topstory/2003/0903rhessi.html[/url]

[QUOTE=Camundongo;16488230]It generally releases energy in the form of gamma radiation, or occasionally in the form of heavy exotic particles. Energy can exist as mass as well, remember.[/QUOTE] True, I didn't think of it reversing the reaction as well. And yeah it usually releases light, hense the blinding flash in the movie, but most of it would be gamma and kill everyone.

[QUOTE=Xenos;16488207]Anti-matter is made in the sun and stays in the sun. Anti-matter is neutralized inside the sun when it interacts with regular matter.[/QUOTE] But, the particles do leave the sun in Solar Flares. That helps to explain the immense amount of energy released. [editline]08:28PM[/editline] [QUOTE=redonkulous;16488541]True, I didn't think of it reversing the reaction as well.

The energy involved is far too high to generate light. And the reaction is nothing like a fission bomb, so don't compare the two.

That annihilation is not realistic at all, First off its not a explosion its annihilation, Second its wrongly shaped. A real annihilation would be as perfectly circular as is physically possible. That and If one gram of Antimatter came in contact with one gram of matter it would obliterate everything within the annihilation range Faster than the human eye can see, So basically one nano second it would be there the next, It would be gone. But there would be a after glow which would linger long after the annihilation. Annihilation releases pure energy particles called photons, Which basicly along with electrons are two of the particles that transfer Electromagnetic energy. Photons are the carriers of the light based part of the spectrum. Tl:Dr Movie physics suck [editline]09:39PM[/editline] [QUOTE=Camundongo;16488818]No, it wouldn't.

[url]http://en.wikipedia.org/wiki/Anti-matter[/url] "Antihydrogen Main article: Antihydrogen [quote]In 1995 CERN announced that it had successfully brought into existence nine antihydrogen atoms by implementing the SLAC/Fermilab concept during the PS210 experiment. The experiment was performed using the Low Energy Antiproton Ring (LEAR), and was led by Walter Oelert and Mario Macri. Fermilab soon confirmed the CERN findings by producing approximately 100 antihydrogen atoms at their facilities."[/quote] well we did make 100 atoms of anti-matter [quote]Cost Antimatter is said to be the most costly substance in existence, with an estimated cost of $62.5 trillion per gram.[12] This is because production is difficult (only a few atoms are produced in reactions in particle accelerators), and because there is higher demand for the other uses of particle accelerators. According to CERN, it has cost a few hundred million Swiss Francs to produce about 1 billionth of a gram.[13] Several NASA Institute for Advanced Concepts-funded studies are exploring whether it might be possible to use magnetic scoops to collect the antimatter that occurs naturally in the Van Allen belts of Earth, and ultimately, the belts of gas giants like Jupiter, hopefully at a lower cost per gram.[14][/quote] [quote]Fuel In antimatter-matter collisions resulting in photon emission, the entire rest mass of the particles is converted to kinetic energy. The energy per unit mass (9×1016 J/kg) is about 10 orders of magnitude greater than chemical energy (compared to TNT at 4.2×106 J/kg, and formation of water at 1.56×107 J/kg), about 4 orders of magnitude greater than nuclear energy that can be liberated today using nuclear fission (about 40 MeV per 238U nucleus transmuted to Lead, or 1.5×1013 J/kg), and about 2 orders of magnitude greater than the best possible from fusion (about 6.3×1014 J/kg for the proton-proton chain). The reaction of 1 kg of antimatter with 1 kg of matter would produce 1.8×1017 J (180 petajoules) of energy (by the mass-energy equivalence formula E = mc²), or the rough equivalent of 47 megatons of TNT. For comparison, Tsar Bomba, the largest nuclear weapon ever detonated, reacted an estimated yield of 50 megatons, which required the use of hundreds of kilograms of fissile material (Uranium/Plutonium).[/quote]

[QUOTE=Themage;16488890] It releases pure energy so its safe to say there might be some photons in there. Scratch that there should be some[/QUOTE] Gamma radiation is also released as photons. In fact the entire electromagnetic spectrum is, from radiowaves to the aformentioned gamma waves. I'd suggest you revise some of your physics.

Let's do a little math. When anti-matter and matter combine, they cancel eachother out and release PURE energy. So let's say we have half a gram of each matter, making for a total of 1 gram. If we use the equation E=MC^2 we will find that ((2/1000)*299,792,458)^2 = 359,502,172,225 joules of energy This is about the equivalent of 86 tons of TNT. But then again, my math is HORRIBLE and I am sure the math I did is not correct. [B]EDIT[/B] It seems I am way off with my math somewhere. The real figure using an online calculator ([url]http://www.1728.com/einstein.htm[/url]) makes one gram of matter into the equivalent of 21.481 kilotons of TNT. In other words, that explosion would have been pretty damn powerful, like if it was fairly high up, the heat would still give everyone second degree burns pretty much instantly. Not only that, the EM burst will also knock all the lights out in the entire city.

Being exposed to a anti-matter blast would like be being exposed to cosmic radiation.

where's JohnnyMo1 when you need him?

Yes everything that happens in fiction books is possible that's why they are called fiction!!

Okay well wouldn't antimatter just disintegrate everything? It's probably impossible to harness antimatter, because it annihilates matter, so even if it was to explode, wouldn't it just disappear when it contacts the particles in the atmosphere along with the clouds?

They stole the effects from this: [media]http://www.youtube.com/watch?v=jI0mugwIsrw[/media] :( And, since when do movies make explosions or anything science realistic?

Excluding the fact that we don't have enough anti-matter for anything bigger than a firecracker-explosion, it all depends on the quantity. I don't know how much that was, but one gram is equal to the Hiroshima bomb, so it probably would have been way bigger. Also the explosion wouldn't look like that, it would look like a nuclear bomb going off (just much bigger).

[QUOTE=ray243;16496161]And, since when do movies make explosions or anything science realistic?[/QUOTE] Realistic = Boring to the general public. [B]EDIT:[/B] They don't.

What a stupid question to ask, it's a ficticious story with ficticious things in, I could write a book and say that the LHC makes giant bubbles appear that shit out planets.

[QUOTE=markg06;16497186]What a stupid question to ask, it's a ficticious story with ficticious things in, I could write a book and say that the LHC makes giant bubbles appear that shit out planets.[/QUOTE] except antimatter is real

With the amount seen in the movie i would say that it would be much more devastating than that, and there may have been other factors in the explosion that would have made it deadlier such as the production of more antimatter or radiation in the form of gamma/X/microwave rays produced by the energy, for all we know it might create either a blackhole or explode inivisibly and if it was realistic and it blow up the vatican and half of rome the movie would have had to end in total tragedy and we wouldnt want ol' Forrest Gump die would we?

[QUOTE=Camundongo;16489898]Gamma rays are the lowest energy radiation an antimatter-matter reaction can cause. Being exposed to a anti-matter blast would like be being exposed to cosmic radiation.[/QUOTE] Not quite. If it was exploded in a vacuum, yes. But same goes for a hydrogen bomb exploded in a vacuum. If exploded on earth, in our atmosphere the actual bomb itself and the surrounding air would absorb a lot of the gamma rays and muons. It would be superheated and explode (which is pretty much what happens with a nuke airblast). The explosion would be visible too because the ionised matter around the actual matter-antimatter explosion would emit blackbody radiation. (Again, the same thing happens with the detonation of a H bomb) [QUOTE=acds;16496351]Excluding the fact that we don't have enough anti-matter for anything bigger than a firecracker-explosion, it all depends on the quantity.

According to wiki they used 1/4 of a gram of anti matter.

[QUOTE=KKram16;16487206]It was a book before it was a movie. I read the book after I read the DaVinci code, because I realized there was a book two. I've never seen the movie - but based on my self opinion - the book is always better than the movie.[/QUOTE] I am aware of that. The movie apparently has a lot of stuff cut out and is less in depth, as with many movies made based on books. I saw the movie but I'm not really into Dan Brown so I couldn't commit to reading the books after the first few chapters.
