The LHC allows scientists to reproduce the conditions that existed within a billionth of a second after the Big Bang by colliding beams of high-energy protons or ions at colossal speeds, close to the speed of light.

This was the moment, around During these first moments all the particles and forces that shape our Universe came into existence, defining what we now see.

The LHC is exactly what its name suggests - a large collider of hadrons any particle made up of quarks. Particles are propelled in two beams going around the LHC to speeds of 11, circuits per seconds, guided by massive superconducting magnets! These two beams are then made to cross paths and some of the particles smash head on into one another.

However, the collider is only one of three essential parts of the LHC project. The other two are:. The LHC is truly global in scope because the LHC project is supported by an enormous international community of scientists and engineers.

The LHC is a machine of extreme hot and cold. When two beams of lead ions collide, they will generate temperatures more than times hotter than the heart of the Sun, concentrated within a minuscule space. By contrast, the 'cryogenic distribution system', which circulates superfluid helium around the accelerator ring, keeps the LHC at a super cool temperature of To sample and record the results of up to million proton collisions per second, physicists and engineers have built gargantuan devices that measure particles with micron precision.

The LHC's detectors have sophisticated electronic trigger systems that precisely measure the passage time of a particle to accuracies in the region of a few billionths of a second. If any of these three obstacles could be overcome — if we could increase the maximum strength of the electromagnets, if we could increase the charge-to-mass ratio of the proton but not by too much , or if we could increase the size of the circular track that particles follow — we could achieve higher energies in our particle collisions, and push past the currently explored frontier of experimental physics.

As it stands today, the best hope we have for finding new physics at the Large Hadron Collider will come from the collection of more data, by increasing the collision rate of particles and running at that increased collision rate for long periods of time.

Ethan Siegel. During the acceleration process the so-called ramp , the energy of protons increases, and the energy of the photons they emit also increases. Once the protons reach their maximum energy, most of the photons are in the ultraviolet range.

Two strange but well-known effects of moving at speeds that are a significant fraction of the speed of light are time dilation moving clocks tick slowly and length contraction. Time dilation tells us that the time experienced by a moving observer is shorter than time experienced by a stationary observer.

Length contraction tells us that a stationary observer will observe a moving object to be shorter in length than it would be if it were at rest. To a proton travelling very close to the speed of light, time would appear to be passing normally. Proton time would seem strange only to an observer outside the LHC, for whom 1 second for the proton would appear to last about 2 hours.

To the proton screaming around the LHC, the mile circumference of the accelerator would appear to take up just about 13 feet. But there is a recording of the proton beam smashing into the graphite core of the beam dump, where particles are sent when scientists want to stop circulating them in the accelerator, and they do land with a bang.
