Would be to check if it falls down. Most theories predict that it should, but there are just enough interesting alternative theories of gravity that this certainly deserves verification.

Now I know how I want to illuminate my garden!
That guy has been producing antimatter for ages now.
If they move on to anti-trolls, I don't think 50,000 is going to cut it anymore. At least not for this site.

I also have just mass produced over 50,000 antihydrogen atoms!
however "Harvard physicist Gerald Gabrielse said: "Our long experience with these very difficult experiments warns that antihydrogen may not have really been produced."
Also, _my_ long experience with antihydrogen tells me I may have not _really_ produced antihydrogen!

Enough to actually get to see the antimatter production ring at Fermilab. Once or twice a year, they go into a maintenance shutdown and give small informal tours.
What used to be the main ring years ago is now the antimatter ring. The magnets were all upgraded to superconductors, and they added buncher/debunchers to the ring to squeeze protons together and apart which, every so often produces a stray anti-proton.
Cern is way ahead of Fermi in that they are producing full anti-atoms, whereas Fermi is only making anti-particles.
Definitely forget about efficiency in production, the guy giving the tour said their electric bill is about a million dollars a month, and they make very few anti-protons from all that power! I bet they're ComEd's best customer. They can't run during the summer air-conditioning months, as they would suck too much energy from the grid in Illinois.
The guide also said as long as the magnets stay supercooled, the anti-protons will stay suspended in the ring for up to a month (unless they hit stray matter and blow up sooner).
After the tour, we got to play stump the genius - one of the research physicists there was nice enough to give a Q & A session. A most informative and cool tour, getting to see something that most "civilians" never get to lay eyes on.
-- You are in a maze of little, twisty passages, all different... --
Now, the Cern particle accelerator in Geneva, Switzerland, has produced more than 50,000.
Sooo, exactly how many hydrogen atoms are in a handful anyway? My first guess would be in the ballpark of "A hell of a lot more than 50k".
Money for nothing, pix for free
Funny, when an institute with a good reputation and high quality equipment publishes the plausible result of their experiments, someone else adds "maybe it's all not real". However when a bunch of people claim that they proved wrong the theory of special relativity with some cheap coax cables, it is left without an expression of doubt. (Not only on slashdot. Here, at least, the posters express their doubt.)
This sig is a true statement, but I cannot prove it.

Furthermore, why should we care?
When's it going to happen dammit? I'm dying here. My brother is like a bog in that he produces cubic FEET of methane on a daily basis. And I have been waiting for the day when somebody produces antimethane. Once someone has made antimethane I will put some of it in my brother's boxers and wait for the fireworks and subsequent explosion. Then I will get his room that bastard.
well, if they didn't really produce anihydrogen, then its gonna be even longer before they can produce antideuterium, so i guess were all gonna have to wait even longer for warp engines

Making antiprotons requires 10 billion times more energy than it produces. For example, the antimatter produced each year at Cern could power a 100 watt light bulb for just 15 minutes.
10 billion lightbulbs! So, they used enough electricity to power a small city for a whole year and the result is....they might have been fooled into a false positive result. I am sure there are lots of better ways of using this power rather than chasing gold at bottoms of rainbows

Antihydrogen has been made before, but only a handful of atoms at a time.
A handfull? Wouldn't that be like... Millions and millions of atoms? Or am I seeing things in the wrong perspective here?
Hate me!

It doesn't count. That person followed the link from the slashdot story.
Well, by the time i posted that i was about goto sleep and noticed that slashdot haven't posted it up and decided to post it, i try to avoid same news than slashdot has, apparently Slashdot was just slow on this one. About visitors, well visitors dropped very highly after problems with windows at nearly a week downtime. Thanks to windows site has needed to be rebuild, redesigned and all content was lost, or actually nearly all but haven't yet added the old stuff, links & downloads... Perhaps next time i use some timestamping device to make people believe ;)
And why to care? Well dunno, i used to think slashdot being fast on news but was very selective... well apparently not...

You can tell they are anti-hydrogen because they all have little goatees and a really bad attitude.
50,000 Atoms is about the size of the point on the end of a sewing pin. If you could bunch these together, then it could be quite visible under a standard microscope.

When anti-matter and matter collide they will become pure energy: E=mc^2 . One gram of anti-matter will give you 0.002*(3*10^8)^2 = 6*10^13 or 60000000000 Joules of enegry.
This will be enough for fast travel within our solar system. Naturally we need to create anti-matter in large quantities first.

Hmmm, why the fuck did ./ reject this same story earlier? Nice going guys, the site has been nothing but quality as of lately!
But we really need scientists to create the crucial elements which are used by science fiction interstellar drives: Handwavium and Analogousite.
for a handful the hand would have to be really, really small. By the way, has anybody thought about the fact that even if we could produce antihydrogen in large quantities, it would be pretty useless as a source of energy. Since its charge would be neutral, you couldn't contain it magnetically. You would have to use antiprotons or an anti-element with a positive or negative charge..

Close to 80 terabits.
eye-blink
Equals 0.1 second. Yes, when you blink your eyes, you miss 10 whole frames of your precious Quake III. Would it be possible to detect closing of eyes and turn off rendering for a split second, giving those cycles to (e.g.) your niced distributed.net or Folding@home client?
handful
Depends on molar density (mol/L but not molarity because it isn't a solution). This is the only one I couldn't find a definite conversion factor for.
human hair
Close to 50 to 100 micrometers.
football field
Approximately 110 m, for both soccer and NFL football. Canadian fields are longer.
football stadium
NFL's Cleveland Browns play in a stadium with a volume of about 3 million cubic meters.
100-watt-lightbulb-second
Given that a watt of power is a joule of energy per second, this equals 100 joules. A kilowatt-hour equals 3.6 megajoules. A horsepower is about 750 watts, so a horsepower-hour is 2.7 megajoules.

It wasn't hydrogen that burned.
The evidence suggests that it was the paint.
There is even evidence that the Hindenberg never existed.
In fact the Germans probably never even had balloons.
In fact Germany never existed. It was all done with paint and mirrors.

Damn straight! That's what we need. More anti-hydrogen. I friggin' HATE hydrogen.
...to mass produce antimatter, but my solution will not fit in this space.
...but I dont understand something about this.
How is the anti-hydrogen stored? Unike the charged anti-particles generally made, I don't see how atoms can be stored because due to their neutrality, a magnetic field doesn't contain them. Any physicist care to explain?
Jeez. How arrogant is that? Scientists at CERN mass-produce
something that others have struggled for small quantities of,
and a pissed off US counterpart reckons that... well, they've
probably made some beginner's mistake???
they didn't make any negative strangelets. I've got plans this weekend, and it would really suck if the world blew up tomorrow. But next week is fine, I can pencil it in. Just need to find me a space shuttle and four idiots...

"Gravity is only a theory, not a fact!"I just an article on MSNBC last night (here) that was an exerpt from William Shatner's book Star Trek: I'm Working on That: A Trek from Science Fiction to Science Fact, where he discusses all sorts of Star Trek technologies, notably warp engines and antimatter.
He discusses the "real science" and problems with space travel, etc., one of them being the difficulties in mass-producing antimatter (said to be the most efficient form of fuel). And then today, we read that CERN (maybe) mass-produced antimatter. Cool! One step closer? :)
Maybe this should have been added here

I would like to protest against these test. Atoms should not be used in experiments. They have not had the oppertunity to become the most they can. I would like to setup a sancuary for these atoms, where they can roam free, and collide at will. A little place called Iraq.
I don't suffer from insanity, I enjoy every minute of it.

Oh, the humanity!
Reading the paper, I'd say the reason to be suspicious is that they seem to only have detected the radiation due to matter-anti-matter annihilation, with the requirement that an anti-proton and positron event happen at pretty much the same time and place. Then they use various comparisons to give additional confidence in the result.
However, as they say, they can't tell what quantum state these atoms are in.
Until they see [anti]hydrogen spectral lines, I'm not 100% sure they have real anti-hydrogen atoms; for now, I'd say 85% sure. Maybe Gabrielse knows of some ways that the same signature can be generated by other crap thrown around by the trapping and mixing processes.
Our long experience with these very difficult experiments warns that antihydrogen may not have really been produced.

Here's a question that a few of us in our lab are wondering about (we're physical chemists):
Why do electrons and positrons annihilate when they come into contact with one another, instead of forming a bound state, like the proton and electron do? I mean, what is it about the proton (rather the quarks that make up the proton) or the positron that either keeps the annihilation from happening or makes the two annihilate? The radial distribution of an electron around a regular proton (roughly exp(-r)) shows that the electron is frequently in the region of the proton. So why doesn't the electron hit the proton and annihilate the same way it would for the positron?

So I follow your link (I love wikipedia). Finally I found a description of Deuterium, which linked to a dscription of "heavy water" - when D replaces hydrogen. An interesting read, but even more interesting was the blurb at the end:
"Heavy water would be an ideal poison for killing someone with, since it is extremely unusual for forensic tests for it to be performed, and it would appear that the person was merely suffering from some mysterious illness; however, heavy water is very expensive, and requires a government license to purchase, making this method of killing someone less attractive in practice."

Where is a good reference source to read about things like electrons, protons, and neutrons? What are they made of? What are quarks? leptons? meons? gluons? What other sub-atomic particles are known to exist? What are theorized? I'm looking for information in reference form so that I can easily refer to it when reading articles such as this (and comments such as these).
Restore America: Dr. Ron Paul for President!
SCSC should never have been started in Texas due to high cost of digging there. Yet it was due to bush politics. Then it was stopped due to democrats. stupid.
Clinton started the next shuttle with the X-33. It gets 95% built and Bush kills it almost immeaditly(or turned it over to the military which is my guess).
This would lowered the cost to space for us. Personally, I think that US should pay attention to china and india for their very cheap programs. India is only charging 15 million / launch.
Nixon(watergate), raygun(iran contra), bush(iran contra), clinton(monicagate), and w(anthrax amongst other things) have been constant liers and manipulators in office.
Bad presidents is what is killing US.
