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 :wink:

what would an anti matter bomb be like h-bombs are real fiery right? nukes are you know nuclear what would anti matter be like in an explosion?

An anti-matter explosion would be about as radioactive as you can get :wink:

Lots of gamma rays and fast-moving particles are produced (all rather bad).

Fast-moving particles?  That would be from gamma rays interacting with surrounding material right, not from the original bomb?

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.

all the mass turns into energy, as you see, energy and mass are interchangable.

Like mentioned before, it becomes high energy photons (light) in the gamma wave spectrum (think three-dimensional laser bomb (?)).

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.

Which would, to be realistic, at most several kilograms of anti-matter. You neither need nor can afford much more :wink:

They must be other particle anti particle pairs right?  Because in the end it should all go to photons.

edit - there is no wikipedia page for it!

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.

Wouldnt that violate conservation laws though?  I dont know this stuff too well, but that doesn't seem right...
