Which is more expensive, building a 100 Rev collided in China or building it at CERN?

Jerry,

I don't know. The tunnel itself is almost certainly much more expensive at CERN. Otoh, at CERN they'd have far less to invest into new infrastructure. In the book, they say, basically, let's do both, wouldn't that be great? I have to agree of course...

"would bring more bang" Paradigmatic bang is exhausted. Theories' price/earnings ratios are Brobdingnagian. Symmetries beget physics. Noetherian symmetries are wrung out and bangless: baryogenesis, the see-saw mechanism, SUSY, dark matter, multiple Higgses, black hole firewall versus information loss; string theory, quantum loop and foam, holography, multiverse....

Proper orthochronous Lorentz symmetries locally leak, for Earth's gravitational potential is neither homogeneous nor isotropic. Internal symmetries are gauge markers. Charge conjugation and time reversal are baryogenesis-compromised. Spatial parity (geometric chirality) must leak. There's your problem - macroscopically test for it. Accelerators are bright lights shining into empty wishes.

In relation to the original functional specifications of the Great Wall the technical specifications are obsolete now.I think the chinese government should hurry up before the functional specifications of the Great Collider are obsolete.

Do they write at all about the collider's maximum energy levels, compared to the LHC?

@Shawn Halayka:

Sabine mentioned 50 to 100 TeV. Doesn't that answer your question?

I think the international particle-physics community should support such a project, and support building it in China, as soon as China has introduced a minimum of democracy and safety standards for workers. Not before.

There were several reasons Switzerland was chosen for CERN: it is centrally located in Europe, it had experience with international organizations, the infrastructure was intact since it was neutral in World War II, it was a neutral country, but also because it has a long democratic tradition, and thus a good place to build up physics after the catastrophe of World War II. Building a collider in China would make it more difficult to encourage reform in China. (Hoping that being friendly first will initiate reform later doesn't work, as can be seen in the example of the friendship of many Western countries with Saudi Arabia. If you compare the laws, customs, society and so on of Saudi Arabia and ISIS, they are essentially the same.)

And while we're at it, maybe Black physicists should avoid Fermilab until the Chicago police get their act together.

@Phillip Helbig Yep, don't know how I missed that. Thank you.

I predict that there might be interesting physics at around 10,000,000 TeV. LOL, no really.

Hi,

taking a historical perspective, fermions are found in the US, bosons in Europe, then I guess China is the only place to find something really new... at last :).
A new kind of statistics???

Cheers..
