Brian Cox: What really goes on at the Large Hadron Collider
 |
||
http://www.ted.com "Rock star physicist" Brian Cox talks about his work on the Large Hadron Collider at CERN. Discussing the biggest of big science in an engaging, accessible way, Cox brings us along on a tour of the massive complex and describes his part in it -- and the vital role it's going to play in understanding our universe.

simoncuming41: I thought the whole LHC experiment was to observe what happened a billion'th of a second after the big bang... Not before it or what caused it?If the Higgs particle does not show up in the LHC, That would also be a good thing. It means that we may need to re-evaluate our way of thinking on how the standard model work's. It's a Win/Win however you look at it.

Hmm, you're right. Well, it's still much cheaper then the military examples. ;p

The total cost of the project €6.4 billion --exceeded by now--. Dunno where you got your 200 mil.^^

Thanks for sharing this HarveyThis concerns me a great deal that alot is guess work that may have very serious consequences that can't be undone once you start this...

I admire his enthusiasm which I do not share because I have a few questions. One big question: How do they know the universe was created from proton collisions? Another: How do they stop the protons colliding before reaching the detector. So they come up with the standard model equation and assumed that there is an unknown Higgs particle. Typical of theoretical physicists: If the equation does not add lets throw in a constant or unknown quantity. It is all assumption -sorry!!! Beryllium?????

My figures: Correct me if I'm wrong, but these are the figures I found: The LHC cost 180mil so far (was supposed to be like 40 mil), the stealth bomber program (development) cost something like 45 billion, and the Iraq war costs (conservatively) about 200 million a day, although some are claiming closer to 700 mil/day.

I don't know where you got your figures from and what currency you're calculating in, but comparably you are wrong. If all this machine is doing is 'learning about the world' then the damage is already done. Time, money and resources for a possible answer from a machine that isn't proven to work. At least you were good to make your comparisons to equally pointless activities, such as war and stealth bombers.

I agree with what you say. I just wanted to add that basic research (like that being done at CERN, when it's up and running) is the most important kind of research. For it opens the door a little wider on reality, in which new ideas (and technology) may enter...

"These" machines? What's the last experimental machine for learning about the world which caused any harm? Also, as far as the cost, it's only about 200mil which is less then 1 percent of the cost of the stealth bomber program, or another way of looking at it, it's the total money spent on the Iraq war EVERY DAY. And this for one of the most important projects.. ever. If anything, they should have been given way much more money, much sooner.
