What's the Latest Music Video from the LHC?

What the title says...

trini · Mar 30, 2010

when can we expect to see a higgs(in terms of energy ranges)?

Borek · Mar 30, 2010

30 minutes and no black hole yet? I feel cheated.

"And boom goes the dynamite"

All kidding aside, this is fantastic! This is even on the front page of CNN... particle physics as popular culture. We live in a strange and wonderful age, even if it can be a pain in the ***. Go LHC!

EDIT: Heh, they're having a bit of a drink in the CMS control room. I see a lot of smiles, so I'd say life is good in Geneva!

MotoH · Mar 30, 2010

Honestly, those guys and gals at the LHC are drinking in almost every photo I see of them!

I had 50 new text messages from CMS, CERN, ATLAS, ALICE, LHCb, LHCf, and USLHC all talking about the new energies. I need to unsubscribe from a couple of those!

0MG!1 Is the LHC on for realz!?

It might ruin the aesthetic, but I can't help but think that site could turn a profit with some advertising all around the "NO", if you published the link in the right places. Tell people to check often!

Tin foil hats?

Actually site has quite a lot of traffic (see alexa.com) - I am surprised.

Oh yes, we could do a BRISK business in tin foil! Hell, trust us, it's PF BRAND foil! For the lazy paranoid we could have pre-made caps, or for the deluded soul who still wants to be fashionable, tinfoil lining tastefully tucked away in a 10-gallaon cowboy hat.

As for the traffic... I wish I could say I'm surprised, but I spend too much time with people to even hope anymore. :cry:

Long, but very good legal brief by UT law professor up on arxiv:

[THE BLACK HOLE CASE: THE INJUNCTION AGAINST THE END OF THE WORLD
http://arxiv.org/pdf/0912.5480

There have been some reputable scientists along the way claiming the case against LHC black holes was not full proof; their story and the story of the LHC responders is discussed, followed by in interesting discussion of how the legal system might approach the argument and assess risk.

I have good friend who is an electrical engineer-turned-lawyer (ghastly, I know, lovely guy though) who is going to eat this up with a spoon. Hell, I'm liking it myself. Thanks mheslep!

Hey it was only a joke :blushing:

Don't forget that how impressive LHC may be for human
standards and how high it's scientific value could be. The energies it produces
are absolutely minute to what occasionally happens above our heads in the
atmosphere.

10⁴ eV: Your old television's Cathode Ray Tube
10¹² eV: Large Hadron Collider
10²⁰ eV: Highest Energy Cosmic Rays in our atmosphere.

The energy ratio between the electrons in the TV in your living room and the LHC is
the same as the ratio between the LHC energies and those of the cosmic rays hitting
our atmosphere.Regards, Hans

...Cosmic rays with single particles with the mass of bloody baseballs sometimes! :laugh: I feel badly for people who suffer over knowledge of the LHC... it's such an achievement for our lifetimes, and it will scratch the itch of curiosity that has driven us before we were homos sapiens sapiens. I call that a net win.

The joke is priceless though... really. They could have put "You're reading this, right jack***?!" but they went with "NO". Minimalist. Genius!

Yes I thought 50 joules was the highest CR ever recorded. That was indeed the first argument used by the folks in the LHC camp - that if it were possible to create some catastrophic event at the LHC higher energy CRs would have done it already. As you'll see if you dig deeper, the existence of CR's by themselves do not foreclose all possibilities of catastrophe:

http://arxiv.org/abs/hep-ph/0106219" , 65 PHYSICAL REV. D 056010, at 1 (2002)

Black Holes at the Large Hadron Collider
Phys. Rev. Lett. 87, 161602 (2001
http://prl.aps.org/abstract/PRL/v87/i16/e161602

The most recent and formidable paper from Max Planck Institute Astrophysicist Rainer Plaga:
Rainer Plaga, On the Potential Catastrophic Risk from Metastable Quantum-black
Holes Produced at Particle Colliders, ARXIV:GEN-PH/0808.1415v2 (Sept. 26, 2008), available
at http://arxiv.org/abs/0808.1415v2

So the complaints were no joke, though as far as I can tell, and I can't tell very well, these propositions have all been shot down by published responses.

For some added amusement, take a peek at that page's source code.

The CoM energy available to create new particles when a 10^20 eV proton collides with another proton at rest is only about

sqrt[2*10^(20)*10^9] eV = 4.5*10^14 eV

A fairly good Q&A FAQ type article on the LHC from the Sunday New York Times 'Week in Review' section:

Perhaps useful for passing around to people wondering what the fuss is about.Title: 'A Primer on the Great Proton Smashup'

It must be proprietary and customized given the application... and the amount of data. That said, I think we have a mentor here who works there...

Anyway, welcome to PF Observables. :smike:
