Going back to the subject of this thread, I visited theregister.co.uk and found a link to a CERN Openlab paper in PDF format, which mentions 2 BOINC projects, SETI@home and Test4Theory@home as examples of distributed volunteer computing. The same site mentions, as usual, only the talk given by Seth Shostak in Congress and not the one by Dan Werthimer, which I downloaded and printed (cannot see the video on my Linux box).

I was just wondering how others feel about the LHC or any other particle accelerator for that matter.
I think it's quite dangerous what they're doing. It's playing with the basic elements of nature.
For instance, they could produce anti matter by accident and thereby annihilate all the matter as we know it!
I really think we should not experiment too much with elements on that scale. It's messing around with the balance that nature built and is still obtaining.
I know I'm not a scientist and I don't know that much about what they're doing but it scares me a bit. Humans can be an intelligent species but we know far from everything and should be very careful with nature. We can read about it all we want but experiments on a level like that are very dangerous IMHO.

LHC is the greatest piece of technology ever produced by humans, IMO. Usually i am embarrassed to call myself human when i see (especially in america) how ignorant most people are but the LHC is one of the things that makes me proud to be human.

As far as producing antimatter by accident, it is my understanding that they produce in purposefully and have it well contained.
"At CERN, physicists make antimatter to study in experiments. The starting point is the Antiproton Decelerator, which slows down antiprotons so that physicists can investigate their properties." http://home.web.cern.ch/topics/antimatter

As far as messing around with nature's balance: we've already screwed up nature's balance with our CO2, CO, CFCs, and gods know what other pollutants we drown/choke/bury our planet in :'(

As far as i understand the energy's that are produced at the LHC are huge but only for the mass that they are colliding because it's concentrated to such a small point. It's kinda like this; I can tap you on the shoulder with hardly any energy and you would barely acknowledge the touch, but if i tapped you with a pin with the same amount of force it would puncture your skin and cause you to bleed. And as far as micro black holes they would evaporate instantly and , i believe that even if they didn't their gravitational field/radius would be so small that you could probably sit on one and you still wouldn't be close enough to feel any gravitational effects.

My only problem with the LHC is that it's not big enough!

Unrelated question here. I added an image to my profile, why is it not next to my posts like everyone elses?

LHC is being upgraded now and it is not working.I am running both LHC@home, which studies the stability of particle orbits,and Test4Theory@home,which simulates events in the LHC, producing a kind of sieve to filter out collision events not significant enough to be analyzed. LHC produces 600 million events/second. I have simulated about 300 million events so far, half of those produced in a second, The LHC demand for computing power and storage is huge.

It's the biggest and most complex scientific instrument ever constructed. It uses the biggest cryogenic installation in the world, and the biggest network of data centers.

Sadly, it happens everywhere...

As far as producing antimatter by accident, it is my understanding that they produce in purposefully and have it well contained.

There is more antimatter produced in nature (by cosmic rays) than by all the accelerators in the world. Indeed, some antimatter rocket design missions propose to harvest antimatter in the Van Allen belts instead of producing it on the ground, because it's cheaper.

As far as i understand the energy's that are produced at the LHC are huge but only for the mass that they are colliding because it's concentrated to such a small point.

The energy per beam in the LHC at nominal power (7 TeV per proton) is 362 MJ, the same than a 400 tonne train moving at 150 km/h. 1 TeV is equivalent to the energy of a flying mosquito. Anyway, there is much more energy stored in the magnets (11,000 MJ at nominal power).

My only problem with the LHC is that it's not big enough!

Yeah!

Here is the roadmap for the future of the LHC:

I'm running the same two @homes. I think the LHC@home is for keeping the proton beam stable and the T4T@home is for exactly what you said. T4T is big packets of info and it takes my laptop days for each wu, but the new LHC wus are being processed really fast.

Actually, there is. I have drug convictions that make it very hard for me to stay for extended periods of time in another country :( I would love to move to Vancouver or something but i don't think they'd give me citizenship. What embarrasses me most about Americans right now is this wave of anti-science that seems to be spreading. Like the climate-change deniers and the people that want creationism to be taught in science classes. I respect their right to hold those beliefs and teach them to their children at home or in church but it is embarrassing when they try to push their religious or, in the case of climate, fuel company sponsored views into the classroom and our government.
For example, if you search in youtube for "is america this stupid" you'll find a 2010 video clip from Rachel Maddow of MSNBC covering a story about how the South Dakota legislature passed a resolution urging public schools in that state to teach kids all the reasons for climate change including the ASTROLOGICAL and THERMOLOGICAL factors. Yeah, they did that. I don't think "thermological" is even a real word but apparently it has something to do with global warming according to the govt of South Dakota. And this type of thinking just seems to be picking up steam in america, that is why i am embarrassed and i would think that these things would embarrass most intelligent people, but maybe it's just me, idk.

Thanks for giving some hard stats! I think i heard someone say that if we had a collider the size of our solar system it could produce enough energy to "see" strings. I'm gonna see how much i have in my change jar and donate it for that collider :)

Haha! Good idea! I'l tell 'em i got lost in the Rockies trying to hike north to avoid the Vietnam war. I'll have to grow a really long beard though to make it look convincing ;)

CERN’s ALPHA experiment measures charge of antihydrogen

Geneva, 3 June 2014. In a paper published in the journal Nature Communications today, the ALPHA experiment at CERN1's Antiproton Decelerator (AD) reports a measurement of the electric charge of antihydrogen atoms, finding it to be compatible with zero to eight decimal places. Although this result comes as no surprise, since hydrogen atoms are electrically neutral, it is the first time that the charge of an antiatom has been measured to high precision.

Magnetic moment of the proton measured with unprecedented precision

One of the biggest riddles in physics is the apparent imbalance between matter and antimatter in our universe. To date, there is no explanation as to why matter and antimatter failed to completely annihilate one another immediately after the big bang and how the surplus matter was created that went on to form the universe as we know it. For the first time a direct and high-precision measurement of the magnetic moment of the proton has been conducted successfully.

CERN announces winners of its first beam line for schools competition

CERN announced the winners of its first beam line for schools competition. Following almost 300 submissions from school groups around the world, two teams have been selected to come to CERN to carry out their own experiments at a CERN beam line. The winners are the “Odysseus' Comrades” team from Varvakios Pilot School in Athens, Greece and the “Dominicuscollege” team from Dominicus College in Nijmegen, the Netherlands.
The laboratory launched the beam line for schools competition. The idea is to make a fully equipped beam line available for high-school students to run an experiment in the same way that the laboratory’s researchers do.

Okay - so my sound card is not working at the moment but am I correct in assuming we have some happy clappy rappers dancing beneath europe and that someone is worried one of them might inadvertent-......

BOOM
beeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeep :)

I'm trying to remember where I read an article that addressed some of the common concerns about CERN. If I find it, I'll post it here, but it had a very reassuring tone as I recall. And apologies for being flippant a little while back :/
