While at Dragon*Con 2012, I gave an incredibly well-attended lecture (standing room only!) on the recent “discovery”(?) of the Higgs boson and our modern theories of particle physics (known as the Standard Model). The lecture was followed by a very fruitful Q&A session which was made all the more interesting because attending the lecture was an engineer who actually works on a detector at the Large Hadron Collider and a theoretical particle physicist!
I recorded the audio of the lecture in order to share it, and I have embedded that audio into the PowerPoint file I used for my lecture. Enjoy! 🙂

You may have heard the recent news that physicists at CERN’s Large Hadron Collider may be narrowing their search for the Higgs Boson. Here’s an update from The Guardian…

Scientists believe they may have caught their first glimpse of the Higgs boson, the so-called God particle that is thought to underpin the subatomic workings of nature.
Physicists Fabiola Gianotti and Guido Tonelli were applauded by hundreds of scientists yesterday as they revealed evidence for the particle amid the debris of hundreds of trillions of proton collisions inside the Large Hadron Collider at Cern, the European particle physics laboratory near Geneva. …
Let me just put a few things into perspective here on this potential (and I stress potential) discovery. First, the data are rather preliminary, and in order to say for sure that there is solid evidence for the Higgs Boson, there need to be more observations to help shore up the statistical analysis. In particle physics, it is not uncommon to see the occasional “discovery” that eventually ends up being merely a statistical anomaly, so more data is better to weed out the anomalies. This section of The Guardian article helps to clarify this point:
… Particle physicists use a “sigma” scale to grade the significance of results, from one to five. One and two sigma results are unreliable because they come and go with statistical fluctuations in the data. A three sigma result counts as an “observation”, while a five sigma result is enough to claim an official discovery. There is less than a one in a million chance of a five sigma result being a statistical fluke.
Gianotti and Tonelli led two separate teams – one using Cern’s Atlas detector, the other using the laboratory’s Compact Muon Solenoid. At their seminar yesterday one team reported a 2.3 sigma bump in their data that could be a Higgs boson weighing 126GeV, while the other reported a 1.9 sigma Higgs signal at a mass of around 124GeV. There is a 1% chance that the Atlas result could be due to a random fluctuation in the data. …
So, by these data, while the 2.3 and 1.9 sigma signals are interesting, they don’t really rise to the level of a solid observation (which, recall, is set at a standard of 3.0 sigma), much less an official discovery.
Also, by “narrowed the search” for the Higgs Boson, what the CERN physicists mean is that they may have narrowed down the energy range in which the Higgs Boson might exist. So, long story short, while these results are of interest, don’t go popping those champagne corks just yet 🙂
The “God Particle”?
I don’t know about you, but I get kind of annoyed at all of this labeling of the hypothetical Higgs Boson as the “God Particle”. I see it as the kind of mushing of religion into science that leads to all manner of philosophically-challenged kind of muddy thinking. First off, depending upon how one defines God (assuming the standard monotheistic version of the Abrahamic god), which is usually defined as a supernatural being, you run into trouble by trying to find natural evidence for a thing which is supposed to be beyond nature.
Second, even if we did discover the Higgs Boson, what would that supposedly tell us about this God? Presumably various armchair theologians argue that such a discovery would be evidence for their view of God (which also begs the question of whether or not it is evidence for one God versus another God). The logic here simply escapes me, and it smacks of the usual “everything is evidence for God” kind of argumentation that passes the lips of too many religious people. And this also brings up a potentially sticky question for the advocates of the “God Particle” label…
What if the Higgs Boson isn’t discovered, despite years of detailed searching? Will these same armchair theologians suddenly give up their belief in their God because the supposed “Particle” which is his/her/its/their fingerprint upon the cosmos was never there to begin with? Somehow I don’t think so, because these believers will merely rationalize away the lack of evidence for the “God Particle”. It is in this sense that I find some people who try to stick the round peg of religion into the square hole of science to be particularly annoying: they want to use science as a method of “proving” their religious beliefs when they think it will work for them, yet they completely dismiss science when it works against them. It’s simply “heads I win, tails you lose” argumentation, and it is both intellectually lazy and disingenuous.
What if we don’t find the Higgs Boson? Science will march on…
This is the thing I really like about science: it never ends. The process of scientific investigation never ceases to ask questions, formulate ideas, and test out those ideas. I think it is entirely possible that in the search for the Higgs Boson, it will never be found; and what then? What if we never find it? Well, that’s when I think things will get really interesting, because that means that much of what we think we know about the Standard Model of physics could very well be wrong. And that would mean that we need to start looking at things differently; this is, to me, the antithesis of dogmatic thinking, and it shows how science is, collectively, the best mechanism we have for stimulating open and free inquiry of the world around us.
Now don’t get me wrong – I would be quite excited if the Higgs Boson were discovered. But I think I would be much more excited if it weren’t found. That would certainly open up a lot more questions, wouldn’t it?
To science! May it march ever onward…

In honor of the recent news of the Large Hadron Collider’s successful run-up to 7.0 TeV collisions and the upcoming Easter weekend, I figure that I’d pass along a humorous little bit that I just stumbled upon. Enjoy!
Hint: the joke is that laymen often state that the LHC is searching for the Higg’s Boson, a.k.a. the “God Particle” 😉
Happy scientists exchanged water for wine
‘It’s not quite the God particle we’ve been looking for, ’said Professor Mann, head of the Atlas Project at CERN, ‘but it’s a miracle nonetheless.’
The particle arose from a collision between a J and an M particle in a way which no one thought possible, and the bright light created sucked in three K particles from the East. Although it only existed for a fraction of a second, scientists are adamant that the Son of God particle will re-appear by Sunday.
‘Make no mistake there’ll be lots written about this and it will become the standard textbook for how we do things in future,’ said Professor Mann. ‘I’ve no doubt it will lead to peace, harmony and wisdom among all men with sandals, beards and tank-tops.’
Excitement at the news was heightened when it was revealed that, on the same day, a technician in the CERN canteen opened a marmite sandwich to discover a perfect image of esteemed physicist Professor Peter Higgs.

As a quick follow up to my recent post about the Large Hadron Collider, there is a new development: the LHC has now actually collided counter-rotating proton beams in collisions reaching the 7.0 TeV energy level (3.5 TeV per beam). As the story below points out, this is the highest level ever recorded for such collisions, and – as you know upon waking up this morning – the planet has survived and no Earth devouring black holes were created in the process. Of course, if you knew anything about the physics involved, you know that such doomsday scenarios are the purest lunacy (here’s 3 reasons why the LHC cannot destroy the planet)…
Geneva atom smasher sets collision record
The world’s largest atom smasher conducted its first experiments at conditions nearing those after the Big Bang, breaking its own record for high-energy collisions with proton beams crashing into each other Tuesday at three times more force than ever before.
I wonder how the conspiracy mongering doomsayers will react to this news? I’ll be on pins and needles 🙂

**Addendum (3/22/2010): Shortly after I wrote the post below, it came to my attention that the proton-proton beams in the LHC haven’t yet actually collided at the 3.5 TeV level yet, but I think that point is moot. It’s also true that the LHC has already conducted proton-proton collisions at greater than TeV levels (up to about 2.36 TeV, it seems)…
And despite this fact, we’re all still here. Of course, I expect the scare mongers to come back with something like “But we don’t know that the planet won’t be destroyed at the next energy level!” By that same token, we don’t know that the Earth won’t be destroyed if we don’t turn the damn thing on, right?
Arguments from ignorance can be used in such silly ways. ‘Nuff said.
The Large Hadron Collider (LHC) is the largest, most complicated piece of machinery ever created by humanity. This humongous particle accelerator also just recently broke, once again, the world record for achieving the highest-energy artificial particle collisions ever in history. Of course, there are some conspiracy-minded scare mongers out there who maintain that the LHC is going to somehow destroy the Earth, presumably because – despite multiple reasons to the contrary – there will be some unknown, magical mechanism by which these artificially-achieved energy levels will kill us all. In short, with no evidence or coherent theory of physics behind their claims, they’re making an argument from ignorance & saying this…
I think not – it didn’t happen in May 2008, and it won’t happen now. As I said, the LHC recently broke that supposedly world-ending energy barrier once again, and we’re all still here. The news is outlined in this Yahoo News story…
Operators of the world’s largest atom smasher on Friday ramped up their massive machine to three times the energy ever previously achieved, in the run-up to experiments probing the secrets of the universe.
The European Organization for Nuclear Research, or CERN, said beams of protons circulated at 3.5 trillion electron volts in both directions around the 27-kilometer (17-mile) tunnel housing the Large Hadron Collider under the Swiss-French border at Geneva.
The next major development is expected in a few days when CERN starts colliding the beams in a new round of research to examine the tiniest particles and forces within the atom in hopes of finding out more about how matter is made up.
The collider in December had already eclipsed the record of the next most powerful machine, the Tevatron at Fermilab outside Chicago, which has been running just shy of a trillion electron volts, or TeV.
The extra energy in Geneva is expected to reveal even more about the unanswered questions of particle physics , such as the existence of dark energy and matter. Scientists hope also to approach on a tiny scale what happened in the first split seconds after the Big Bang, which they theorize was the creation of the universe some 14 billion years ago.
CERN has reported a series of successes since the collider was restarted last year after 14 months of repairs and improvements following a spectacular failure when scientists initially tried to get the machine going.
CERN improved the machine during a 2 1/2-month winter shutdown to be able to operate at the higher energy .
“Getting the beams to 3.5 TeV is testimony to the soundness of the LHC’s overall design, and the improvements we’ve made since the breakdown in September 2008,” said Steve Myers, CERN’s director for accelerators and technology.
It’ll be interesting to see how the scare mongering pseudoscientists rationalize away this one, but I’m sure they’ll find some way to do it.

In a story that is making the rounds on the Internet, a UFO was spotted in the skies over Norway. It took the form of a strange, spiraling bright light high in the sky that had a mysterious glow to it. Here’s a photo of the UFO…
And a Youtube video about the phenomenon has gathered a whopping 1.9 million hits in just a single day!…
Needless to say, this is a very interesting phenomenon, with some – to say the least – very interesting explanations being offered by various people for what it could have been. These, as the reporter in the video above, range from the relatively mundane (such as a failed Russian missile launch) to the usual nonsense from the woo-crowd (alien visitors) to the outright bizarre (a rogue black hole). So, in the absence of solid evidence, what is the most likely explanation?
Perhaps this news article can shed a little light on this mystery…

Hooray! 😀 The Large Hadron Collider (LHC) in Europe has switched back on after being offline for a year…
Europe: Proton beams circulate in Big Bang machine
GENEVA – Scientists switched on the world’s largest atom smasher Friday night for the first time since the $10 billion machine suffered a spectacular failure more than a year ago.
It took a year of repairs before beams of protons circulated late Friday in the Large Hadron Collider for the first time since it was heavily damaged by a simple electrical fault.
Circulation of the beams was a significant leap forward. The European Organization for Nuclear Research has taken the restart of the collider step by step to avoid further setbacks as it moves toward new scientific experiments — probably starting in January — regarding the makeup of matter and the universe.
And, as I’ve blogged about before, where there is science being done by physicists via particle accelerators like the LHC, there are also pseudoscientific nuts who maintain that it’s going to destroy the Earth. Balderdash! Here are 3 good reasons why the LHC experiments are no danger to our planet.
I should also point out one more piece of good news regarding the re-starting of the LHC: despite all of the doomsday scenarios by the conspiracy-mongering pseudoscientists – the Earth survived 😉

One of the things I did at Dragon*Con a couple of weeks ago was to give a talk on the physics of the Large Hadron Collider. The last part of the talk dealt specifically with the claims that the LHC will destroy the Earth. My response to this nonsense claim:
No, really, don’t panic… the Large Hadron Collider is NOT going to destroy the Earth. Yes, I know what the cranks have said, and I know that words such as “black hole“, “strangelet” and “exotic matter” get thrown around to make them sound like they know physics from their buttholes… but really, it’s going to be fine. Here’s why:

As a quick follow up to a recent post – LHC Lunacy & Doomsday Scenarios – I wanted to share with you an online discussion I had with a physics woo on this topic. The conversation with James Blodgett, who seems to have a history of opposing the Large Hadron Collider on pseudoscientific grounds, is recorded on the Science & Technology subforum of the JREF Forum.
Allow me to, as a lesson in the kind of thinking employed by many pseudoscientists, point out some of the more egregious statements & arguments by Mr. Blodgett and why they are so off-base…

In my last post, I took various physics woo-meisters to task for being what I call “Einstein cranks”. However, another class of physics crank deserves some notice, if only because they have made their cranky ideas so public and obvious. These are the cranks who believe the Large Hadron Collider is going to destroy the Earth by the creation of a black hole or strangelet.
**Aside: Even if the worst-case scenario were to come true, and a planet-eating black hole were to be formed in the LHC, this blog entry explains quite clearly why there is no concern.
All I can say is… balderdash… complete and utter pseudoscientific fear-mongering & balderdash. The following video from The Daily Show illustrates just how silly these arguments can be…
The arguments from these folks range from simply not understanding basic physics to delusional conspiracy mongering. Walter Wagner, the man in the video above, illustrates a perfect storm of woo regarding this issue. Allow me to list some of the flaws in his reasoning more specifically…
