Aligarh Muslim University participates in the Big Bang Experiment at LHC, CERN
By Dr. M. Mohsin Khan
These days Print and Electronic media around the globe are discussing about the start up of LHC ( Large Hadron Collider ), the giant accelerating machine of its kind having a circumference of 27 Km. situated at the Swiss-French border in Geneva Switzerland. There are six experiments to be performed at the LHC, namely, ALICE, CMS, ATLAS, LHCb, LHCf and TOTEM. It took 20 years for its construction and a sum of US $ 40 billion were spent.
It is like a dream come true for about 4000 physicists, engineers and technicians from 30 countries all over the World that today on 10th of September, 2008 the LHC is ready to collide a proton on another proton at an energy of 14TeV(~100000 times the energy produced by an atom bomb ). The collisions at LHC will create a temperature about 100000 times the temperature of the core of the Sun. These collisions will re-create the conditions of the BIG BANG. Critics call it the experiment that could cause the end of the world. It is mankind's most ambitious experiment, which seeks to create the initial moments after the Big Bang, and the birth of the Universe.
The Large Hadron Collider (LHC) buried 100 metre deep is expected to reveal the secrets of Universe. The collider accelerates proton beam/ion beams until they almost acquire the speed of light and gain enormous amount of energy circling the structure 11245 times per second.
Scientists hope to put under the scanner the existing laws of physics describing the fundamental nature of matter.
