Amazing, I wonder what this means for creationists and more importantly - our understanding of our universe?

sharpneli• 14 years ago

Nothing at this stage.

From what I've gathered this is so expected result that nothing really changes, right now atleast. It'll take a while until something new will come out of this.

As an example this could be summarized like someone showing that P!=NP, it would be totally expected and nothing would really change.

p.s P!=NP would be a bigger result though, the comparison was just for something that is overwhelmingly expected.

I don't mean any offense, since the question itself is valid, so I'll offer one of my own: Why does it matter what creationists make of it?

jmcqk6• 14 years ago

Given that this is science, it doesn't mean anything to creationists.

JonnieCache• 14 years ago

On the contrary, some creationists make great efforts to engage science on it's own terms, with hilarious results: http://rationalwiki.org/wiki/C-decay

Why should it mean anything special for creationists?

God either created the Higgs or he didn't. This science illuminates God. That's all.

It's not an argument for or against creationism.

(Although if you believe God created the world, then just say it. There is nothing wrong with believing that. But don't hide behind a psudo-science like creationism.)

archangel_one• 14 years ago

> Why should it mean anything special for creationists?

I guess maybe this is a misconception based on the media having come up with the stupid label of "the God particle"?

molmalo3• 14 years ago

In high school I had a fellow student that was ortodox. So, he believed that the Bible should be taken as a literal story.

So, when I asked him if he believed in Dinosaurs, he said that some fossils were from before the Great Flood, and that those animals where the beasts that died a few thousand years ago.

When I asked him about Carbon-14, and that those fossils were dated millions of years ago, his answer was simple: Two options, those experiments are wrong, or is God testing our faith.

This could be God testing our faith again for them, so... nothing will change.

mike_ivanov• 14 years ago

> ortodox

Did you mean fundamentalist? Orthodox is something totally different.

i_cannot_hack• 14 years ago

Is this question a result of the name "God particle" confusing people again? In that case, it is just a stupid name that science journalist, not scientist, decided to go with. It doesn't mean anything at all, and Higg's boson has nothing to do with god.

adestefan2• 14 years ago

As I noted above, the media did not come up with the god particle reference.

ygmelnikova2• 14 years ago

The anti-creationists have become a religion unto themselves, complete with persecutions and indulgences.

CamperBob2• 14 years ago

This is true only if creationists' bullshit is as valid as our reality.

So, no.

sanxiyn• 14 years ago

It's cute that ATLAS spokesperson says 126 and CMS spokesperson says 125. Then CERN says 125-126.

confutio• 14 years ago

Can someone please dummify this result a little bit? what does this mean for particle physics in the future? does it confirm any theories?

Luc• 14 years ago

Here's a pretty good Q&A that talks about this: http://www.cam.ac.uk/research/news/particle-consistent-with-...

What stood out to me from watching the presentation was the incredible integrity of the physicists involved. The CMS group had 2 sets of data with > 5 sigma significance, but chose to also show weaker data that actually reduced the significance slightly. Consider the enormous effort spent to show that the result was not some background fluke - two separate detectors, running 2 completely different means of detection, each with their own sets of computer programs verifying the results. Finally both show almost exactly the same result (although the masses are slightly different at this point)!

Given that tevatron also sees similar (although weaker) results, the confirmation is beyond doubt. And what an achievement - the first fundamental particle observed since the quarks in the 1980's! An incredible victory for theoretical models developed almost 50 years ago (no wonder Peter Higgs had tears in this eyes)!

Combining the brilliance of the theoreticians with the integrity of experimentalists is what makes science the pinnacle of human achievement (IMO), and makes me proud to be human today.

molmalo3• 14 years ago

> So, chose to also show weaker data that actually reduced the significance slightly

Well, they are not trying to convince anyone here. They are trying to prove something. So, choosing to hide that data would've been dumb, as the two possible outcomes would have equally interesting I think: proving that the Higgs Boson does exists, or proving that it doesn't.

Beyond that, yeah, it's a good day today for science :) !!!

pessimist2• 14 years ago

> Well, they are not trying to convince anyone here. They are trying to prove something.

A nobel prize is at stake! If ATLAS only had the results and not CMS, they would have lost the nobel. For them to put aside personal glory for science is impressive.

wpietri2• 14 years ago

> Well, they are not trying to convince anyone here. They are trying to prove something.

And that's the impressive part. Finding this out cost circa $10 billion. To get that dough, they had to convince a lot of politicians (and hundreds of millions of taxpayers) that this was worth it.

To the general public, a clear result is much more satisfying than, "Well, gosh, the data is ambiguous; we need another $10 billion to get some solid answers." It takes a lot of integrity to go to the lengths they did. I salute them!

A minor correction -- the tau neutrino wasn't discovered until 2000.

hessenwolf4• 14 years ago

Really interesting article: so we're basically back to studying the Aether, right? Or did I get that wrong? The only cause of mass is the particles moving through a vast pervasive invisible field?

blueprint• 14 years ago

Perhaps it would be more accurate to say that we need to be more careful about rejecting theories that simply sound like that of the luminiferous aether on the surface.

FYI aethers can be explained mathematically nowadays.

hessenwolf4• 14 years ago

The link isn't bad.

(the comment oddly doesn't follow my comment??)

mkr-hn2• 14 years ago

I'm going to summarize this based on my limited understanding, and hopefully someone can confirm or deny.

This is important because it confirmed the accuracy of the way we conceptualize the structure of the universe.

That means both the people who start and fund projects know that the basis of modern physics is sound. So the time and money won't be wasted by a surprise "nope, Higgs-boson isn't there" in the middle of a project based on the belief that it is.

sp332• 14 years ago

Yup, this was the last particle predicted by the Standard Model. In addition to not having any evidence that it existed, we also didn't know exactly how massive it was, or how likely it was to show up in high-energy collisions.

Unfortunately, the Standard Model still doesn't have a good explanation for how quantum mechanics and gravity work together, so we know it's not complete. But at least the particle menagerie seems to be full :)

This is a great comment: "Think about it this way. Let’s say you’re at the target range, and the Lone Ranger is shooting at clay pidgins right nearby. Obviously you’ll want to know if he’s shooting silver bullets, right? But you can’t look at them while they’re still tied up in the gun. You can’t look at them after they’ve hit the pidgin. And they’re traveling too fast to study while they’re in flight. The only way you can see if they’re silver bullets is based on how the pidgin gets blown to pieces."

"The Higgs boson has a very short lifetime outside of other subatomic particles. The only way for us to study them is to smash those particles together and see the results of the decay. Based on how the Higgs decays (blows itself to pieces), we can infer its existence."

SoftwareMaven2• 14 years ago

It's even harder than that, because it turns out full metal jackets will cause the pigeons to blow apart into the same pieces, so it's not just the pieces, but things like the direction and velocity of those pieces.

mrpollo2• 14 years ago

Can someone please explain to me what would the immediate technological advancement be if this is true?, what applications would this have? (Already watched the video and read the FAQ, still a lot that is not clear to me)

amackera• 14 years ago

This has been covered a lot, but in short: this is basic science that will have far-reaching implications in the long term. It gives us a greater understanding of the universe, and confirms a hypothesis that heretofore had no direct evidence.

The immediate short term won't see any technological advancement, but as with all basic science we will see outcomes in the future.

Science is in fact not engineering.

mrpollo2• 14 years ago

Thanks for your response, I understand science is not engineering I was just not sure if I was missing some other immediate implications. The more you know.

ieureur3• 14 years ago

None in the foreseeable future.

SoftwareMaven2• 14 years ago

My science-fiction addled brain can't help but be taken to things like anti-gravity when we start talking about understanding the particle the causes mass. If we could alter the field, we could make things much less massive, making Michael J Fox's hover board that much closer to a reality.

Of course, this is baseless conjecture and, even if true someday, will be nothing like immediate. However, without understanding the field, we won't be able to affect the field (we may never be able to affect the field when we do understand it).

yaix• 14 years ago

Immediate probably none, but we now know that the Standard Model is not wrong with regards to the Higgs, and the Standard Model is the basis of all kinds of real-world calculations.

just for the record and to please the prospective downvoting mob, here are my experimental observations consistent with the cern experimental domain in order to warn any non-westerners:

So, will we get more understanding about the shape of the universe?

http://en.wikipedia.org/wiki/Shape_of_the_universe

Can we now conclude what'll happen if we go right to the edge of the universe with speed of light? Without any further debates?

mserdarsanli• 14 years ago

There is no such thing as 'edge of the universe'

hessenwolf4• 14 years ago

Speculative.

This is probably the best headline for this that I've seen on a news aggregation site.
