The world of physics takes a bold leap forward with a single laborious finding

The world's two most advanced particle detector experiments -- ATLAS and CMS -- have both detected signs of a particle that eluded physicists for almost a half century -- a particle researchers suspect is the Higgs boson.

I. Hunting for Higgs -- Inside the Most Expensive Machine Created by Man

The two detectors are housed within a 17 mile in circumference underground tunnel in the Alps, a tunnel which is chilled to temperatures colder then outer space.  The particle accelerator and attached detection apparatus is a triumph of engineering, and at $10B USD is the single most expensive piece of laboratory equipment in the history of mankind.
 

Brought online in 2008, the collider suffered from early hiccups, typical of large particle accelerators.  But before long it was setting records and gathering data which led to the discovery of new exotic particles.

But the biggest payoff for the high cost and years of effort came when the European Organization for Nuclear Research (CERN) announced that they had detected signs of the Higgs-like boson, a particle whose operation necessitates a super-powerful collider and world class detection equipment.

Just a couple days before U.S. Department of Energy's FermiLab published data from their now-defunct Tevatron indicating that they were 99.8 percent (roughly 3σ) sure that they had detected a Higgs-like boson.  That level of confidence is called an "observation" in particle physics.

II. From "Observation" to "Discovery"

By contrast the threshold of confidence for a "discovery" is 5σ -- and CERN delivered precisely that on Wednesday.

Using data gleaned from record 7 TeV and 8 TeV proton collisions, the CMS and ATLAS teams jointly pinpointed a Higgs boson or similar particle to within the 125-126 GeV mass region, with the requisite 5σ confidence.

That result is strengthened by the fact that the observation at the Tevatron predicted a mass between 115 and 135 GeV.

The CMS experiment spokesperson Joe Incandela comments:

The results are preliminary but the 5 sigma signal at around 125 GeV we’re seeing is dramatic. This is indeed a new particle. We know it must be a boson and it’s the heaviest boson ever found.  The implications are very significant and it is precisely for this reason that we must be extremely diligent in all of our studies and cross-checks.

ATLAS experiment spokesperson Fabiola Gianotti comments:

We observe in our data clear signs of a new particle, at the level of 5 sigma, in the mass region around 126 GeV. The outstanding performance of the LHC and ATLAS and the huge efforts of many people have brought us to this exciting stage, but a little more time is needed to prepare these results for publication.

III. The Hunt is Over, But the Discoveries Have Just Begun

The discovery of the new boson is a momentous day for particle physics, and one that comes despite wise caution on the parts of the men and women involved.  Physicists were wary of jumping the gun and announcing the discovery, lest they make a mistake and alienate a public who already is less than highly interested in taking a trip into the cerebral land of modern particle physics.

The Higgs boson is theorized to give rise to the so-called Higgs mechanism, a form of electroweak symmetry breaking.  A simple analogy of this complex effect is to think of a sort of "sticky field" that coats particles like a spoon dipping through a jar of honey.  This "sticky" effect is thought to give protons, neutrons, and electrons -- the building blocks of matter that most of us are familiar with -- their mass.

To summarize in the simplest terms, researchers are now have detected a particle which they believe may give all standard particles their mass.

The discovery takes researchers a step closer to confirming the "Standard Model of particle physics", a theory which in turn opens the door to more advanced applications, such as string theory.

Much work remains to be done, though.  The particle, while observed with a high measure of confidence, was poorly quantified, aside from its mass.  By further probing observed Higgs-like bosons, researchers will be able to tune, accept, or reject certain compenents of Standard Model theory.  These changes could help researchers better understand mysterious components that make up much of the non-visible universe -- such as dark matter and energy.

In short, Higgs boson -- also nicknamed the "Goddamn particle" or "God Particle", for short, by a famous Nobel laureate -- is only the first step in a bold journey for mankind, a journey which will take humans, quite literally where no man has gone before.

Blastman seems to be picking up what I'm putting down. :)

I can't explain true "nothingness" and it is a paradox if we think of it in terms of absolutes. Even if there was some kind of void with "nothing" in it, the fact that it is a void with nothing in it is something in itself.

The infinite number line example makes it easier to understand why we are "nothing" or at least zero. If you are standing on a number line that extends infinitely in either direction, no matter how far you travel in either direct you never move from point zero. You're always in the "middle"...despite never changing position or changing anything you can move.

Now expand the idea of number line to a coordinate graph with infinite axis. We can understand 3D space, and it's the same thing...no matter were we go within that graph we're always at point zero.

I think that is how existence works on a fundamental level. It's really just nothing, but since nothing can also be anything simultaneously we get to exist as just one of an infinite number of somethings.

What we end up perceiving is what we want to see. We can't understand the concept of infinity, but we can understand that point 0 and point 5 are 5 spaces apart. That limitation is being created by us, it's not a limitation created by something or someone else and it's not actually there. On an infinite number line point 5 IS point 0 and counting their relative positions is basically irrelevant...in fact, numbering the line is a limitation in itself being created by us.

Going on a bit of a tangent, consider that it is impossible for a perfect curve, circle or sphere to exist within our universe. Even if it appears round, when examined at the appropriate scale its edge will always be "stepped". Kind of odd that the only shapes that can truly exist are straight lines and angles, while anything curved is simply an illusion. I wonder if this has any significance.

Matter is simply large pockets of "nothing" loosely, or densely, held together by molecules. It's really not THAT hard to comprehend that outer space is a much more vast area of pockets of "nothing" interspersed with dense galaxies, radiation, and other molecules. Space is actually not a true vacuum, there's about 2 hydrogen atoms per cubic meter of space on average. So it's not "nothing".

This philosophical trip you're on, at some point, needs to acknowledge that there IS an actual reality on which we exist.

I think it's time to cut down on the LSD.

You're missing it though. There might be two hydrogen atoms per cubic meter but within that vast meter (to a hydrogen atom it is quite vast), what is between them? What is that "nothing" that segments them?

We can't define it. At best we can say it is "spacetime" and per the poster of this particular thread whom wrote a book, has a marvelous equation which sums it up nicely with simplicity, g=tc^2, if you plot the curvature and its subsequent ripples and folds, the correlation is quite obvious. But graphing it doesn't solve it. It helps us visualize something. Something intangible that at first glance must just be a simple brane (or medium) but after great thought, as incomprehensible as it might be, is far from insignificant.

This "nothing" manipulates, defines and influences all of us completely. Yet, despite this massive contribution to not just entropy but also perceived order (and do not forget the statistical chaos in the smallest of the small that is merely quantifiable but neigh observable), we still don't know what it is.

Until we do, everything else we do is moot and subject to great change. If you ask any physicist I'm sure they'll tell you the same thing.

We have to understand what this "nothing" is. It is as I see it, the key to everything around us that we can see, hold, imagine... or even beyond our wildest comprehension.

The "nothing" is dark matter and dark energy. Forming a "cosmic scaffold" that holds spacetime, the Universe, together.

Just because we perceive it as "nothing", doesn't make it so.

How you can you be so sure? Heck, we don't even know what dark matter and energy are. They serve as nothing more than terminology placeholders to fill a gap that we have zero explanation for. We have theorized they exist but beyond that it is a mystery. We know the universe is accelerating in its expansion and rather than use the cosmological constant which itself was another placeholder than Einstein himself used to make his equations "work" regarding a stationary universe--we've created stubs.

That is correct and that is why we must solve it.

Because we can observe it's effects. It might not be a perfect theory, but that's the best we have. And when more evidence comes into play, theories will be revised and further understanding begins.

That's how science works. You and Eric can philosophize all you want, but that kind of thinking doesn't really get us anywhere.

Well I don't know what to tell ya, people are working on it. :)

On the contrary; being unwilling or unable to look at things from a perspective other than your own ensures that many mysteries will remain mysteries.

We're talking about things that scientists are spending a lot of time and money trying to figure out, but due to the abstract nature of the subject matter and the general unwillingness of most scientists to truly think (rather than to simply observe) holds progress back.

Performing a scientific experiment is like asking a question - you need to be able to think this way to determine the optimal questions (experiments) to ask.

Eric, shut up. Science cannot work under your philosophical proclamations. Because if "reality is a human invention", and we're just making up everything we perceive, then the truth is simply what we imagine it to be. In which case things like science, proof, facts, and truth are subjective in the extreme.

I'm glad you got your Liberal Arts Major degree, but when it comes to science, your opinions are useless and actually dangerous.

Much like a video game has rules, and to win at the game you play by those rules, so does our particular niche of existence. Regardless of whether the rules are fabricated by our minds or by some external force, they exist as far as we're concerned and we have not found a way to transcend them.

Science, the way it is practiced today, may enable us to gain more mastery over our little niche (i.e. the game world and its pre-defined ruleset) but it has little chance of going beyond that much in the same way your in-game avatar could not exist outside of the game even if it was aware that it was an avatar within a game (remember, the avatar doesn't really exist; it's just an illusion).

I noticed that you still haven't answered my other question about viewing yourself drinking coffee on the scale of an atom. Why not? You're not going to even take a stab at it?

If I am an atom and I see an apparently chaotic cluster of atoms and other particles, explain to me why the "absolute, indisputable reality" I should accept is you drinking a cup of coffee.

Are you trying to say that if I look at only a single atom of the coffee mug scene, that all i'm going to understand is that there is only a single atom (that's what i observed). Where as if I step back and look at the big picture i'll go "gee whiz, there is a whole lot more to this than I thought".

Wow, you are truly a Davinci of our modern era. Nobody, has heard of this concept prior these postings. How naive and ignorant of you to suggest that others haven't contemplated this also.

Also your game analogy is bit bogus, yeah the avatar exists, it exists within the box as 1 & 0's resulting in pixels etc.

The infinite line thought, did you fail math?? Yeah if you setup an infinite line it goes on forever, but if you move in one direction for a while, you are most definately not in the same spot you just where. It's called relativity, when you set an axis no matter the extremity's of the axis you have a set/start point, and resolution. When you compare any other point you are always comparing it to another set point. If you travel along the x axis, then yeah, delta x, if you are travelling along the y axis, delta y. You can make a far out claim that, you are still in the same place because infinity imposes this proof upon us. Well guess what, singularities also exist in maths', they often mean, an error has occured, we lack the capability to describe it with that concept of mathematics. It's exactly why the whole field of imaginary numbers where created.
