Big Bang Theory

The Big Bang Theory refers to the beginning of our universe. According to the theory the universe was formed about 13.5 million years ago from a hot and dense state that expanded very fast.

That primary explosion is called Big Bang. According to the theory the universe is still expanding today, the distance between planets, stars and galaxies expanding continuously.

The Big Bang theory is based on the Albert Einstein’s general relativity theory which also points to the existence of the black holes. In the early phases the universe was consisting in high density energy, extremely high temperatures and pressures, and cooled down in the process of expanding rapidly.

As the universe cooled, appeared the gravitation and after about 400,000 years appeared the first atoms of hydrogen. Next, over a very long period of time the gravitational force contributed to the formation of gas clouds, stars and galaxies.

Is expected that the experiments conducted with the Large Hadron Collider (LHC) to answer many questions regarding the beginning of the universe and the way it evolved. The largest and highest-energy particle accelerator in the world, LHC was built by the European Organization for Nuclear Research (CERN). The construction of LHC was approved in 1995 and in September 2008 CERN successfully fired the first protons around the circuit.

In March 2010 the first beams collision marked the start of the LHC scientific research program. With a budget estimated at over 9 billion dollars as of 2010, this experiment is the most expensive ever recorded. There than 10,000 scientists and engineers from over 100 countries involved in this project as well as hundreds of universities and laboratories that work together in order to solve many physics mysteries and to answer the most fundamental questions: how was created the universe and how did it evolved into its current form?
