It would be more interesting if they did not find it. LHC needs more exciting results to justify its cost.

- ThomPete 14y agoI think that is a general misconception. Each time we increase our understanding of something, we also gain new tools to solve questions. Think of this as long term investments for humanity, then the price is microscopic.
- zerostar07 14y agoThere is a lot of politics in this. Particle Physics is not the only area where we have unanswered questions or need more tools (but it does have a spectacular track record and influential community behind it).
- ThomPete 14y agoOh I agree there are many other areas. But no other area than physics have given us so many inventions, because no other area is a fundamental as this. We are playing with as close to universals as we can come here. Just think about the amount of years it took from the inception of QM up to today and how much it has given us in return. Extraordinay returns require extraordinary investments. But yes there is a limit obviously.
- Symmetry 14y agoWhat I think the GP is saying is that its unfortunate that this experiment only confirmed our understanding of physics rather than increasing it. We only learned that our suppositions about QM were correct, there weren't any of the anomalies that have led to new physics in the past. Personally, I'd say that $9B is a fair price to pay for confirmation, but I'd have been happier to get more.
- PakG1 14y agoWhether or not that's true, it is true that type of thinking can result in poor science.
- shrikant 14y agoDon't you mean "if they found it doesn't exist"? A classic case of "evidence of absence" vs. "absence of evidence", and your comment reads like the latter.
- jmcqk6 14y agoActually, it's possible to to prove that something doesn't exist. It depends on how well defined it is. For example, you can take the dragon in the garage from Sagan's Demon Haunted World. If you're not familiar with it, the example is a guy who claims to have a dragon in his garage. When you attempt to look for it, not being able to see it, the guy says 'it's an invisible dragon.' And likewise the story continues, each time, there is a reason provided for why the dragon cannot be found. The issue here is that it's a very poorly defined dragon. Let's consider the strongly defined dragon. If I claim that there is an 8ft, red, visible, fire breathing dragon sitting on the ground in my back yard, a simple search will disprove that statement. There is no evidence to be found of that dragon, and it can be safe to say that it doesn't exist. However, if I then say, 'well, the dragon isn't really visible,' then I've changed what you're looking for, and the search must be conducted with those new parameters. The case with the higgs is similar. It can be possible to say 'a higgs with these properties does (or does not) exist.' If you say 'well, what if it has these different properties' well, it doesn't invalidate those previous results; it just provides you with something new to do. The core mistake here is that 'absence of evidence' is not always 'evidence of absence,' but many times it is. In the same way that 'correlation is not causation' but many times it is.
- zerostar07 14y agoWell, either of the two would stir the waters and bring new ideas to the table.
- jfoutz 14y agoIs 9 billion a lot? as an american, It's hard to see that as more than the operational cost of a fighter jet. Just trying to manage the data from the LHC lead directly to the world wide web. I'm pretty sure there were a bunch of other technologies developed, like the superconducting cable that power those magnets, that will have a big long term payoff. I mean, sure, it's a lot of money. I think we're getting NASA moon mission level of return on our money. Paying a bunch of smart people solve really hard problems does good things for everyone.
- eblume 14y agoI think you meant CERN, not LHC there. LHC was built rather recently, the web has been around far longer.
- zerostar07 14y agoI 'm a little wary whether we get our money's worth from those huge international projects like LHC or the ISS. I would like to see a comparison of the general impact that previous smaller collaborations had compared to projects of this size.

- theorique 14y agoas an american, It's hard to see that as more than the operational cost of a fighter jet. Not sure if you're being ironic but a fighter jet typically costs a couple of orders of magnitude less than $9B - even the hugely expensive JSF (F-35) is 'only' $200M unit cost.

- jfoutz 14y agoYou're right. My estimate is off by a bit over an order of magnitude for the f-22. they cost just under 50,000 an hour to operate (http://hatch.senate.gov/public/_files/USAFResponse.pdf http://hatch.senate.gov/public/_files/USAFResponse.pdf) you could certainly operate more than 10 of them for 9 billion. I think a B-2 will come close to that though. 1 billion in todays dollars and 130,000 an hour for operational costs. -it's not actually 2000 a minute, there's a bunch of work before and after each flight.
- uvTwitch 14y agoConsider that LHC cost only a fraction the ridiculous amount of money wasted each year on war. It justifies it's cost merely by it's existence, increasing fascination in understanding, instead of destruction.
- InclinedPlane 14y agoIt's a steal. We spent a quarter of a trillion dollars on the Shuttle program and ISS. And about $133 billion on the GM bailout. The Higgs theory will have unknown implications that will resound for centuries. Spending 0.03% of a single year's GDP of the US+EU is a small price to pay for such a fundamental insight into the nature of our Universe.
