CERN Scientists Capture Antimatter For Record 16 Minutes

[Sonic Doctor]

I traditionally watch most of all of that every year, because I just love the technology and universe.

holy crap, how do you manage to get anything done!!

also, i'd love to see a 'stark reactor' kind of technology come from this or a tng universe star-drive for the I.N space-station

can you imagine that? a tng drive module bolted to the space-station, it would be epic

people go on about bombs, but seeeriously..
do we need an antimatter bomb? really? we can pretty-much blow the planet in half as it is we're really just approaching the point of a planetary self destruct button.

Well, now that I think about it, it might not be every year, at the most over a 2 year cycle.

There are 8760 hours in a year, I sleep maybe for a small bit over 1/4th of those hours, and all of everything Star Trek is probably a little over 1200 hours. That still leaves well over 5000 hours a year to do other things(like watch Doctor Who), but as I said I probably do it over two years. Oh, and I usually don't watch all of the original series, because I like the stuff that came after it better.

But yes, it would be cool to see all that technology in action.

Can someone please explain to me what an "anti-matter bomb" is, and whether it has any chance of coming to exist in reality or whether its just some joke made by the OP?

Also, "exploding reality"? What does that even mean?

"exploding reality" is a misnomer. An anti-matter "bomb" (also a misnomer, since it wouldn't require a detonator; any matter would do) would, unlike traditional bombs or nuclear weapons, annihilate matter, which is to say the matter that it came into contact with, along with the anti-matter material would be converted back into energy (as all matter and anti-matter is just densely compounded energy structures), then 100% of that energy would be released. This is unlike a nuclear weapon or traditional bomb which changes the states of matter, moves matter and produces radiation but annihilating very little or no matter (and conversely having very low efficencies).

When the universe was created 14 billion years ago, close to equal amounts of matter and antimatter were created. 99.9% of that matter was annihilated almost instantly. All the matter in universe is 0.01% of what was created by the big bang.

However, the possibility of an anti-matter weapon being produced with current technology is negligable. It would take half a gram of anti-matter to reproduce the destructive force of the bomb dropped on Hiroshima, which would take a couple of billion years to produce.

It's generally considered by phycicists extremely unlikely to ever occur. It's not worth worrying about, there are much more likely (and still incredibly unlikely) cataclysmic events that could happen naturally.

Many, many, many words.

Well, I'm feeling particularly appeasing today and don't want to pen a counterpoint to examine the nature of a relative conception of reality, so I've edited out the bit about exploding the thing.

I was tempted to replace it with "which would almost certainly create awesome superheroes," but you'd likely take offense at that too, wouldn't you Captain Buzzkill?

 

[Alar]

I can imagine how freaking excited those scientists must have been... did they literally jump from a few seconds to sixteen minutes? Something tells me they might've been hoping for a minute at best, and then they get this? There must have been fanboy and fangirl squeeing that one typically only hears at a major announcement during an anime convention!

 

[Xaio30]

What we need right now is antistupid. Preferably in huge quantities before the few remaining smart people are overrun and humanity goes back to the caves.

This!
A billion mother f*cking times, this!

Seriously, embroid that with golden thread on the biggest piece of cloth you can find and I will wave it until my bones break and my brain explodes.

 

[Android2137]

Scientists, why?! Why are you all so determined to kill us all?! Someone hold me. I'm scared.

 

[ImprovizoR]

I want this to allow warp speed in the future!

Seriously though this is really exiting. I can't wait to find out what they'll learn about it.

The creation of superheroes isn't so bad. Very few people would mistake that for a real thing.

I'm not sure what you mean by "relative conception of reality". I have a sneaking suspicion that you are trying to throw words around that let you pretend it's impossible to be right or wrong about something, but that may be because I've recently reread Cryptonomicon

If you think pointing out misinformation in a news article is a buzzkill, then I'm just going to have to be thankful that you edited out what you did and hope that you get bored of journalism quickly and move on to other things.

It should be noted here that nuclear bombs and antimatter have very little to do with each other, other than that both are capable of releasing a lot of energy in a short amount of time by converting mass to energy.

That's a good point, I shouldn't have jumped from one to the other without clarifying.

Despite it's enormous energy-release capabilities, it doesn't work well as a source of fuel because 1) it's hard to make, 2) you can't store it in conventional containers without it combining with them, and 3) the second law of thermodynamics says that, as with all fuels, in the process of making antimatter from scratch you lose more energy than you would get back from it.

Antimatter might be useful for portable power sources. You can't send an interstellar probe out of the system with a massive solar array, but you can use a massive solar array here on Earth to power a device that makes antimatter.

But this only makes sense if there's a low-energy trick to storing the stuff. Otherwise you'd need a conventional generator to power the storage device, so why not use the conventional generator to power the probe instead.

I have to imagine we'll have nuclear fusion figured out well before any practical applications for antimatter arise.

So when Cern vanishes in a blink of light we'll know what it was atleast.

Very unlikely as you would have to be able to store anti matter which is not possible at the moment. Basically when matter and anti matter combine they release lots of energy to make your own equation to find out how and do this.

1 gram of matter and 1 gram of anti matter would result in a bomb of a yield 86 tonnes of TNT. For playing around to see how powerful you can get just take the value of Matter so say 1kg and the speed of light squared 9*10^16 and multiply by 2. That is the energy. For tonne TNT yield then divide than by 4.184*10^9.

Could you provide a citation for what you've said about anti-matter? Or failing that, be willing to tell me what your profession is?

 

[Leppy]

"...in 2004, the annual production of antiprotons at CERN was several picograms at a cost of $20 million. This means to produce 1 gram of antimatter, CERN would need to spend 100 quadrillion dollars and run the antimatter factory for 100 billion years." I'd stop worrying.

Scientists don't want to kill you. They've probably saved or improved your life many times over, both before and after you were born. This journalist and others like him, along with Hollywood and various others, sometimes have a difficult time writing things that are interesting and so they find cheap ways to create drama to engage their readers/viewers. Science, because it is often poorly understood by much of the general public, is a spooky enough thing to many people that it lends itself to these tactics the way old mansions lend themselves to horror films.

CERN is not, nor is anyone else, producing antimatter for an energy source or weapon. It is far too impractical, difficult, and expensive to do so. Its greatest value is for use in medical equipment to help diagnose diseases (like I said earlier, science generally tries to save or improve lives rather than end them) and work out some flaws in our current understanding of the universe.

I highly recommend taking any news story about science with a huge bag of salt unless it's from a site or publisher that is specifically dedicated to helping the public understand science. Most news organizations are very unconcerned with accuracy in such stories, and many of the writers on this site like to completely make things up in their stories, even while they complain about mainstream journalists making things up about video games.

If you're curious, a few posts back you should be able to find a link to a faq on the CERN site explaining what antimatter is, what it behaves like, why they are making and studying it, and why no one in their right mind would or could ever use it as a power source or weapon.

 

[Keava]

Wait. Wait. Didn't they did that like month ago? PopSci [http://www.popsci.com/science/article/2011-05/cern-physicists-trap-antimatter-full-quarter-hour-eclipsing-previous-efforts] had article about it happening on 3rd May. Im bit confused? Maybe they got stuck in time loop? *enter dramatic music*

 

[vrbtny]

The first thing I would do if I worked at CERN would be to turn to my co-worker and say "I dare you to stick your hand in there."

Try the CERN faq. The link to it was posted on the second page. Failing that, the equations here are very straightforward and you can do them yourself. You need the equation E=mc^2 (Energy=mass*the speed of light squared), the value for the speed of light, and the rate at which CERN produces antimatter, which you can get from the above-mentioned link. Don't take my word for it, google is your friend.

The important thing here is that even though a gram of antimatter can destroy a city, it takes an unimaginable amount of atoms of a substance to make a gram of it (in hydrogen's case, somewhere around 600,000,000,000,000,000,000,000 atoms (Avogadro's number times the molar mass of hydrogen, google is your friend), and CERN can only produce antimatter a few atoms at a time, and has no way to store them for any great length of time. As the article states, 300 atoms held for 16 minutes before losing them all is a huge record.

BTW I'm not the guy you were responding to, just happened to be in the area. I'm a science illustrator.

Edit: Whoops, molar mass of hydrogen is more like 2 grams/mol than 1, so that big number should be 1,200,000,000,000,000,000,000,000, not 600,000,000,000,000,000,000,000.

My bad.

 

[ResonanceSD]

I will admit that the possibility of a resonance cascade senario is extremely unlikely, but why do we have to wear these ridiculous ties?

I for one welcome our new combin-


Wait, wait, I for one welcome the opportunity to be GORDON FREAKING FREEMAN.

...I meant it as a joke.

 

[ProjectTrinity]

Ohgosh, my sciencetardation is at its best here.

I need a re-explanation.....in composer language. That means, pretend you're talking to a 7 year old when I ask: What does this mean, what does it do, and how can it benefit me us?
