Particle beams injected into LHC for first time since September 2008

Engineers working on the Large Hadron Collider (LHC) have successfully injected beams of particles into two sections of the vast machine.

An LHC spokesperson said this was the first time particle beams had been inside the LHC since it was shut down late in September 2008.

Scientists working on the giant particle accelerator described the success as "a milestone".

They plan to circulate a beam around the 27km-long tunnel in November.

On 23 and 25 October, beams of protons and of lead ions were injected into the LHC ring, and successfully guided both clockwise and anti-clockwise through two of the eight sectors. Each sector is approximately 3.5km long.

The extreme cold allows the magnets inside the LHC, which align and accelerate the beam, to become "superconducting". This means they channel electric current with zero resistance and very little power loss.

The Big Bang, the LHC and the Evolution of the Creation of the Universe by Brian Cox

In "There's probably no God, the Atheists Guide to Christmas" edited by Ariane Sherine, Brian Cox has a chapter on the Big Bang titled "The Large Hadron Collider: A scientific creation story".

The LHC recreates the conditions of the universe less than a billionth of a second after the big bang. The job of the LHC is too study the universe during the time when the Higgs particles are thought to have been generated. The history of the universe is thus:

• 13.7 billion years ago universe begins (t=0)
• gravity separates from the other forces of nature (t+10-43 seconds)
• exponential expansion of universe (t+10-36 s)
• from size of electron to size of melon (t+10-32 s)
• with formation of sub-atomic particles
• and Higgs field (t+10-12 s)
• gives mass to sub-atomic particles
• Higgs acts like cosmic treacle
• if Higgs particles aka Higgs Boson, aka The God Particle (Leon Lederman) exist (after 40 years we don't know) then Higgs Boson must be created in LHC (Standard Model)
• Higgs particles decays too quickly to be seen even in LHC 
• but Muon will be seen from decay of Higgs particle 
• Higgs Boson is tens or hundreds of times heavier than the protons that were smashed together (mini big bang) to create it (E=mc2). Energy=mass
• because Higgs particles are light enough to show up in LHC
• if Higgs particles are NOT found in LHC 
• some other mechanism (Minimally Supersymetric Standard Model?) will show up in LHC which creates mass
• and explains Dark Matter

After t+10-12 s time we already know what happened to the universe because smaller cousins to LHC (eg Fermilab Tevatron?) have been working for decades:-

• 4 forces of nature (strong nuclear, electromagnetic, weak, gravity) formed (t+10-6 s)
• strong nuclear force
• binds quarks together in nucleus of atom
• electromagnetism
• holds electrons in place around nucleus
• weak force
• allows sun to shine, explains radioactive decay
• gravity
• is missing from Standard model
• creates infinities when gravity is added 
• if treat particles as tiny points, when they come infinitely close together, gravity becomes infinitely strong 
• by treating particles as strings (not tiny points) we have a way for gravity to work
• but gravity is included in Einstein's General Relativity
• a Theory of Everything would combine Standard model with General Relativity
• String Theory combines all particles and forces (and makes a decent cup of coffee!)
• quarks and leptons interact
• quarks stick together to give protons & neutrons, neutrinos roam universe (t+1 s)
• protons & neutrons form elements (t+3 minutes)
• Hydrogen 75% : Helium 25% ratio fixed (t+30 m)
• Light as Photons set free from dense universe: cosmic microwave background (t+ 380,000 years)
• gravity collapses H & He to form stars
• 4 forces of nature interact: x3 He fuse to give Carbon
• more fusions give oxygen and other light elements
• stars run out of fuel, explode 
• scattering C & Oxygen & other light elements
• creating Gold, Silver & other heavy elements
• gravity forms stars & dense rocky planets orbit
• on at least one planet, occurs self replication & life & us!
