CERN Wants to Upgrade LHC's Luminosity by 10 Times

I was told there'd be no math

It's a non quantum sub ev world out there. Gravitation and mass are due to a very different form of particle or particles, no resemblance with Higgs. Look for DCE research in Sweden, if you want to see the shape of the things to come. Eventually STR will be marginalized and space and mass will be seen as interchangeable.

[citation][nom]f-14[/nom]you fail at math, all it leads to is an arms race that just triples and multiplies by 100x's costing more tax payer dollars. take your social communism back to grade school math and learn how miserably it fails with out the theft of the wealth of other nations and the death of a great many people also.[/citation]
How the hell do you think particle accelerators lead to an arms race? They aren't weapons, nor can they be weaponized, moron.

But by all means, lets stop all basic science because some idiot on the internet says it will lead to an arms race!

God you're stupid.

Rantoc, China does not own most our debt.

Looks like the poster with a jumbled mess of a name beat me to commenting on the cost of LHC. $9US billion (for the ENTIRE PROJECT: that includes the estimated costs of running it for years and years) is a mere drop in the bucket compared to the REAL big-ticket items that're being paid for just by US Taxpayers; CERN's budget actually hardly comes from the USA; as all 20 of its member states are European. The USA is merely an "observer state." Of course, leave it to most to assume that the US government pays for EVERYTHING in the world.

But even if it was US taxpayer dollars... Given the benefits of the LHC, how does it rank compared to the USA's big-ticket "investments," like the trillions spent not just on wars in Iraq and Afghanistan, but also spent bailing out banks and other big companies left and right?

Perhaps my only complaint with the LHC is just how agonizingly slow they're ramping things up. Power-wise, they're at a combined collision energy of 7.0 TeV, or 50%. It won't be for another year or so before they'll finally get up to the advertised 100% of 14.0 TeV. And, as we've seen here, they're also still ramping up the luminosity, too: full power is supposed to be around 10e35, with this "10x luminosity" being just another step towards that. And of course, a proposed hardware upgrade for 2018 would allow that to be jacked up to 10e36.

Oh, and those numbers? That actually stands for collisions per cubic centimeter, per second. hetneo is slightly off, as "candelas" has nothing to do with this. The Candela is ALREADY calculated on a spread over area, though in there it's measured in terms of vector, (square steradian) whereas here it's measured on a 3-dimensional space. That, and candelas measure power (watts) versus here it's a dimensionless number of collisions, which is irrelevant to the energy (and hence total power) of these collisions.
