all this stuff about black holes being made from the CERN proton collider[?] and junk got me thinking

how do you create anti matter?

wikipedia confused me too much. so uh... someone explain it to me in much simpler words?

i figure theres at least one person who knows this on ug

Step 1) See if it matters.
Step 2) If it doesn't matter, it's antimatter. If it does matter, it's matter.
Step 3) Fin.

read the book Angels & Demons

i cant really remember it exactly, but the book explained it perfect.

i think anti matter is theoretical. And if those guys do create it, they will be officially dividing by zero

To be honest, wikipedia explains it pretty simply. I don't think I could make it more understandable. It's not an easy task.

Angels & Demons is fiction. Antimatter is not theoretical. It definitely exists.

This might belong in the LHC thread

but don't be to worried about it, the LHC that is being launched soon PROBABLY won't produce anti matter. And even if it did produce some, I do not believe it could produce enough to cause any problems on earth whatsoever. I've been studying this for months

EDIT: Anyway, anti-matter is simply the absence of matter. Matter is everything, anti matter is the absence of matter. So, if anti matter was unleashed in the earth, it would eat away at stuff, things would disappear. Black holes are made of anti matter.

And to the post's above recommending you read angels and demons, its a really fascinating book, some interesting ideas.

im not worried about the use of antimatter, anti matter bombs, or anything like that

the creation of it confuses me

The existence of positrons was first postulated in 1928 by Paul Dirac as a consequence of the Dirac equation. In 1932, positrons were discovered by Carl D. Anderson, who gave the positron its name.[3] The positron was the first evidence of antimatter and was discovered by passing cosmic rays through a cloud chamber and a lead plate surrounded by a magnet to distinguish the particles by bending differently charged particles in different directions. => i.e. its happening all the time from cosmic rays

and http://en.wikipedia.org/wiki/Beta_decay also works

Don't do this.
The book is decent, but do not take it as an account of how to produce anti-matter.


Anti-matter is basically the exact opposite of matter.

If matter is composed of an atom with its corresponding electrons, protons and neutrons and all that jazz, then anti-matter has the opposite. Positrons (positively charged electrons) or anti-electron, and an anti-proton (a negatively charged proton), etc.

Wikipedia says that anti-matter is formed in an environment with sufficient temperature (energy).

I completely disagree with this. The absence of matter is just a vacuum. Anti-matter is something completely different.

AntiMatter= Matter, but with opposite spin, and opposite charge.

Antimatter is used by us. A lot. We use it in PET scanners. Beta plus decay, which is entirely natural, gives off antimatter.

I'm waiting for someone to try and tell me it'll work as a viable energy source.

I laughed all the way through Angels in Demons when they got shit-scared about AM bombs. I think I read somewhere that the entire amount of AM we've produced would just about power a light bulb? And AM is so ridiculously inefficient, People Might as well just use H Bombs instead.

theres the idea that you could use it to power a spacecraft, as you'd need very little fuel (mass wise at least compared to thousands of litres of rocket fuel)

but its not exactly cheap
In 2004, the annual production of antiprotons at the Antiproton Decelerator facility of CERN was several picograms at a cost of $20 million. Thus, at the current level of production, one gram of antimatter would cost $100 quadrillion and would take 100 billion years to produc

also, we need to think up an antimatter-resistant container for it

i know that but that book is based on facts.

Basically to create antimatter you need to have a container (if you want to contain it) that prevents the antimatter from touching ANYTHING, otherwise rendering everyone around it ****ed


it might not be impossible but the idea is ****ed up


EDIT: i never meant that that book was completely true but it explains the basic gist of antimatter relatively well from what i understand

It would work in space. You'd need liquid fuel rockets to get you off the earth though.

Antimatter is the opposite of matter (duh)

Its created with antiparticles, which are found in space. Lets say antimatter touches matter, it fuses to create energy and it will cause a huge explosion. I actually found out that if you were to use antimatter with a car, you could get nearly 6 light years to the gallon of energy, There is a base under Chicago that is trying to make antiparticles by having protons and that stuff smash into each other, the only problem is that in about 20 years of doing this, its only created 0.000001 milligrams of it.

Antimatter is worthless.

Nice to see a fellow fan

It's not so much the fact that it doesn't make that much energy (which it does)

It's the fact that you need to supply so much energy to make it in the first place, so your net energy produced is orders of magnitude less efficient than using something like Fusion.

But you guys already knew that

if antimatter can be created by PET scans[positrons] and such, why does it take such large machines such as the proton accelerator to actually create it?

This is obviously not true. We have nuclear powered submarines and I'm quite sure 1 nuclear reactor powers a LOT more than just one light bulb let alone 432432 power plants...I don't know much about anti-matter. I know it's ridiculously to think of using it as an energy source due to it's habit to explode or w/e.
Fixed to show what the thing was that's dumb...

What's not true?
#33
the thing is, we can dig a big hole in the ground and filter through rocks and end up with a useable chunk of uranium

we have to artificially create antimatter which for the time being, isn't really viable and the whole generation process isn't terribly efficient either

You do realize that H-bombs and nuclear submarines are not exactly the same thing, right?
And that nuclear power does not have much to do with antimatter?

I am kind of confused about your statement . . .

It's not created by PET scans, it's used by them.

To create antimatter, you need really, really huge amounts of energy. According to e=mc^2, matter is energy. If you get a load of energy, it can condense into matter. Now, the conservation of energy must apply to matter as well, so you get matter and antimatter, giving you a sum of zero (one particle for every antiparticle). So, collide protons together using a particle accelerator, and you'll get loads of energy, condensing into matter and antimatter.

Terribly worded, but you should get the basic idea.

Also, read Steven Hawking's "A Brief History of Time".

Ah, you give me too much credit my friend, but lo!

All it takes is google!

And henceforth, I may look my challenger in the monitor, hold up two fingers in defiant salute, blow a raspberry, and tell said errant squire to "Jog on."

Live, from the Pit, this was, Lord Bishek

I bid you Adieu, and goodnight.

EDIT: Seriously though, Young Arthur, just give it a search on google. Its hard to realise how ridiculously expensive this stuff is.
