Question about the LHC
#8917706 - 09/12/08 10:37 AM (15 years, 8 months ago) |
|

I saw something and the discover channel a few years ago I believe about the LHC, that they were trying to make anti-mater or that it could make anti-mater? I remember some old guy on the show saying something along the lines that the result of the molecules colliding could result in oppositely charged atoms and thats what anti-mater is considered? Please feel free to correct any of this gibberish. I want it.

Yea, all the major colliders have been making anti-matter for quite some time now.
Anti-matter is just like normal matter but it has an opposite charge. When normal matter and anti-matter collide they annihilate each other and produce radiation.
Anit-matter is the most expensive stuff on earth, it take millions of dollars just to make a few particles.

Despite its exotic nature, antimatter is starting to find its way out of the lab and into practical applications, eg. see PET scans. Soon it won't seem that "exotic" at all, although creating enough to use for fuel or weapons is apparently still be a ways off.

yeah PET scans use anti-mater, i could see it being used as a weapon...a very very powerful weapon.

That is a long way off, I think...you would have to make about a kilogram of the stuff in order to make an explosion like a 20 megaton thermonuclear bomb.
A kilo of antimatter is a lot of antimatter! I think you'll have troubles making enough of it so as to be useful, or making it fast enough to be useful, or storing it for any amount of time.
Far easier to just use a couple big h-bombs

An anti-matter explosion would be about as radioactive as you can get 
Lots of gamma rays and fast-moving particles are produced (all rather bad).

That leads me to believe that using antimatter bombs would be considered a war crime, since they are worse than the worst dirty bomb when it comes to radiation, and giving cancer to anyone not behind a lead shield or a few miles of rock (thank god the Earth is round).
On the other hand, when it comes to totally fucking destroying something, an antimatter bomb would kick an h-bombs ass. While an h-bomb might just spread an object in the epicenter across several miles of terrain in all directions, an antimatter bomb would wipe from existence the amount of matter equivalent to its mass.

I was under the impression that only leptons annihilate directly into gamma rays. As electrons don't count for much of the mass in matter, they wouldn't account for much of the devastating effects.
You should take a look at all the weird fast-moving particles (relativistic) that come out of a proton-antiproton annihilation.

A bit less than that, assuming you want the earth to still be around when done. In nuclear fission/fusion, only a fraction of the fuel is actually converted to energy rather than the doubling you get with matter/antimatter.

No...there are some electrons produced, as well as a multitude of neutrinos (where most of the energy goes, actually).

Only a fraction of the matter/antimatter would be converted into useful energy (useful from a destruction point of view) - most of the energy is carried off by neutrinos.

How would it violate any laws?
The conservation laws state only that the "energy + matter" going in to the reaction be EQUAL to the "energy + matter" coming out of the reaction. Remember that neutrinos have a very insignificant mass, and electrons have just a little bit more mass...so to have a proton and antiproton annihilate each other can result in quite a number of neutrinos and a few electrons along side those gamma photons.

Sorry, should have been more specific. I mean conservation of charge, lepton and baryon numbers. It has to put out anti particles that will also annihilate to jive with conservation laws. Unless Im missing something...

From wiki:
Quote:
Over 99.9% of the mass of neutral antimatter is accounted for by antiprotons and antineutrons. Their annihilation with protons and neutrons is a complicated process. A proton-antiproton pair can annihilate into a number of charged and neutral relativistic pions. Neutral pions, in turn, decay almost immediately into gamma rays; charged pions travel a few tens of meters and then decay further into muons and neutrinos. Finally, the muons decay into electrons and more neutrinos. Most of the energy (about 60%) is carried away by neutrinos, which have almost no interaction with matter and thus escape into outer space.

They must mean positrons and electrons (sometimes the distinction is glossed over). Because you start with zero charge and zero lepton number and end up with charge and non zero-lepton?
Well, Im satisfied now that conservation is intact.
Its interesting that most of the energy is carried away in neutrinos. Need to make the bomb out of straight positrons then.

Now thats what I call a scary nuclear bomb! One that goes off if its switched off 
The A-bomb dropped over Hiroshima was armed aboard the plane with barometric ignition during flight. If the plane had dropped below a certain altitude it would've gone off.
Nukes pwn antimatter where it comes to budget. One kiloton of BOOM
requires 20 grams of Lithium Deuteride or 55 grams of Uranium 235. The LiD costs about 50 bucks.

It would probably be 'better' as a space based delivery system, either for ship to ship or ship to planet. That way it would be relativly isolated. Perhaps there are space faring civilizations waging war with them right now... or maybe not.
I wonder how far out we could detect some alien anti-matter warfare or experiments, and if it would be distinguishable from noise?

Not true.
It (little boy) was initiated by radar altimeter. Two of the four radar triggers had to agree before a detonation was initiated. The barometric system was a backup to ensure safety, and could not initiate the detonation (it could only prevent it). There was also a timer to ensure that a detonation could not happen until the bomb had fallen for at least 15 seconds.

Lo Dis me first post. Aside A scientist working on bringing the whole relativity thing into one mathematical formula happened to do so. Can't remember it but it was so clean and precise as well as beautiful (In a mathematician kinda way!) He reflected on it extensively. He realized it had "Two" Solutions and both were Right. After considerable deliberation, He conceived the theory of another universe BUT Exactly Opposite to ours in every way. So became the first thought possibility of ANTIMATTER. Most out of box. More later SCEK (Like Oil Sheik)

Electrons are point particles, meaning they aren't made of anything else (we think).
