[QUOTE=Contag;29619098]Oh god the amount of work required to make a kilo of anti-matter.[/QUOTE]
burning the banknotes needed to finance the production of 1-kilo of antimatter would probably release more energy than the antimatter itself
I've always wondered how to safely store anti-matter. I mean, that shit explodes when it comes into contact with matter, right?
Me thinks, matter has - electrons and + protons. Anti-matter has + electrons and - protons. The one thing both types of matter have that's the same is neutrons, they're neutral. So would it be possible to create a container which has an inside wall consisting of neutrons?

they use magnetic fields to hold them
[url=http://en.wikipedia.org/wiki/Neutronium]also if you had a wall made of neutron matter it would be pretty fucking heavy[/url]

I know that now, after reading the article. But the neutron shield concept is what I always thought the solution would be.
How heavy would neutrons be? Bone crushing heavy? Earth crust shattering heavy?
I thought it said that an animator was trapped for over fifteen minutes

well to put it this way, over 98% of the mass in an atom is in the nucleus, while over 98% of the space an atom takes up is a void in which the electrons "orbit" around.
The article is kinda misleading, it takes atleast 18 minutes to cook rice properly.
Upwards of 30 minutes if they're brown rice.

This also doesn't account for frying, which one might want to do after boiling the rice to add flavor and texture.
Frying them could double or triple the preparation time depending on the batch of rice, capacity of your frying pan and personal fried-rice preference.
Serve with light chicken breasts and you have yourself a nice healthy meal.
Optional: add peppers, maize or onions when frying the rice if you're feeling adventurous!
Hell yeah we're now 0.05% closer to warp drive!

Add in some cold pressed hemp seed oil for maximum health benefits!
Hmm, magnets are totally awesome. This just proves it.
Oh, antimatter is cool too. Not as cool as magnets, though..
I wonder if they all stood around observing it, their stomachs turning inside out over whether they were about to blow half the earth into oblivion.

Scientists doesn't afraid of anything. :downs:
I remember seeing a show on antimatter and the desire to make an "antimatter bomb"
Shits scary
I seriously hope their experiments dont start a black hole or something
/paranoid

How's that?
I'd much rather an antimatter bomb of comparable strength to a nuclear bomb.
I wonder what anti-food would taste like if you could somehow taste it?

Only better
I can't understand half the shit that you people post in this thread.
And I'm in college entry Physics.
[QUOTE=Contag;29619098]I remember reading somewhere that it's thought that the spectral lines will be identical to normal matter - but that this with a grain of salt, because I may have read that in a journal, or on one of the "But if I do X and then Y (even though both are impossible) then will time travel exist??!?" threads that pop up here every now and again.[/QUOTE]
Well being out of phase wouldn't change the nature of the spectral lines. They'd still have the same wavelength (and hence frequency), but I figured that because we were talking a positive charge and not a negative charge here, perhaps the emitted light would be 'upside down' (or half a wavelength out of phase)... or perhaps not. Just hypothesising.
[QUOTE=FalconKrunch;29617009]No, antimatter is unstable so it just disappears.[/QUOTE]
Antimatter is exactly the same as matter but with the opposite charge.
[Quote]Recent data released by CERN states that, when fully operational, their facilities are capable of producing 107 antiprotons per minute.[29] Assuming an 100% conversion of antiprotons to antihydrogen, it would take [b]100 billion years[/b] to produce 1 gram or 1 mole of antihydrogen [/quote]
[Quote] estimated $250 million could produce 10 milligrams of positrons (equivalent to [b]$25 billion per gram[/b]) [/Quote]
Not exactly the fastest or cheapest process atm. :v:
Still cool though.
Science!
Thats one hell of a record.
This is huge progress.

Now, to find how to produce it a tad faster.
Fuckin Miracles.
[QUOTE=sltungle;29617664]They wanted to know if it occupies the same energy levels as hydrogen, which got me wondering: if anti-hydrogen absorbed a photon of the correct wavelength would it emit a positron when it dropped in energy again? And if so: why? How does the photoelectric effect 'know' whether the atom is a 'regular' atom, or an anti-atom in order to determine if an electron, or positron should be ejected when it loses energy.
Also, what differences would that produce in the spectral lines produced? Light that's EM field is 1/2 wavelength out of phase?[/QUOTE]
Having had time to think about this question (I posted it at about 7AM this morning my time) I think I've figured out the first part. I was completely wrong in asking that question in the first place because the photoelectric effect doesn't work the way I thought it did at 7AM in the morning. I don't even know why I asked that. The positrons are directly lost from the material: more aren't created from the energy of the light.
Second part I'm still working on. I figure if you had a hydrogen atom, and an anti-hydrogen atom, and you spaced them apart with a distance of a whole number multiple of their first emission wavelength, and the hydrogen atom emitted a wavelength of light, and the anti-hydrogen emitted one of the same wavelength but 1/2 wavelength out of phase you'd end up with the waves destructively interfering in the middle. You wouldn't even know they were there!
Fuck yeah, wave functions!

You can't just have a wall of neutrons. They have to be bonded somehow to be kept in place. Also, there are anti-neutrons aswell.

Now do high precision spectroscopy and look for CPT violations, if any.
