What is Grand unification theory?
{{no sources|date=February 2014}} '''Grand unification theory''' or '''GUT''' is a [[model(universe)|model]] that tries to describe the [[universe]]. It says that three [[Force (physics)|forces]] - [[electromagnetism| electromagnetic]], [[weak interaction|weak]] and [[strong interaction| strong]] forces - were once combined into a single force. These are three of the fundamental four forces of nature, which are responsible for all of the pushes and pulls in the universe. If [[gravity]] is also combined with these forces, then the GUT will become the proposed [[Theory of Everything]]. Because GUT models have more [[Space dimensions|dimensions]] than currently known, there has not been a single GUT. [[Particle accelerator|Particle accelerators]], like the [[Large Hadron Collider]] have been built to test these GUTs indirectly, as it is too complex to observe effects on particles without them. GUT was first proposed by researchers from [[CERN]] in the 1970s. The discovery of the [[Higgs Boson]] and other such recent discoveries will get scientists closer to knowing which GUT is correct, and ultimately know the Theory of Everything. This theory was given by Pakistani scientist [[Abdus Salam]], who shared the Noble Prize with Weinberg and Glashow for it in 1979. There have been numerous failed attempts to form a Grand Unified Theory, and many scientists believe that it is impossible¹. Although the attempts have not been successful so far, we have gained invaluable insight and understanding through the endeavours to find the Grand Unified Theory.
