The Large Hadron Collider: Machine Big Bang

The Large Hadron Collider (LHC) is a gigantic scientific instrument near Geneva, where it spans the border between Switzerland and France about 100 m underground. It is a particle accelerator used by physicists to study the smallest known particles – the fundamental building blocks of all things. It will revolutionise our understanding, from the minuscule world deep within atoms to the vastness of the Universe.

Two beams of subatomic particles called 'hadrons' – either protons or lead ions – will travel in opposite directions inside the circular accelerator, gaining energy with every lap. Physicists will use the LHC to recreate the conditions just after the Big Bang, by colliding the two beams head-on at very high energy. Teams of physicists from around the world will analyse the particles created in the collisions using special detectors in a number of experiments dedicated to the LHC.

There are many theories as to what will result from these collisions, but what's for sure is that a brave new world of physics will emerge from the new accelerator, as knowledge in particle physics goes on to describe the workings of the Universe. For decades, the Standard Model of particle physics has served physicists well as a means of understanding the fundamental laws of Nature, but it does not tell the whole story. Only experimental data using the higher energies reached by the LHC can push knowledge forward, challenging those who seek confirmation of established knowledge, and those who dare to dream beyond the paradigm.

Large Hadron Collider

Here are some quick facts:
- 20-year work-in-progress
- A team of 7,000 physicists from more than 80 nations
- 27 kilometers in circumference, 175 meters underground
- facilitating head-on collision of protons, traveling very near the speed-of-light
- each tunnel is big enough to run a train through it.
- temperatures generated: more than 1000,000 times hotter than the sun's core
- superconducting magnets are cooled to a temperature colder than in deep space

Nice Pictures. Information appears to be good. Let me read and brood then I'll tell more.
