Scientists prepare CERN collider in hunt for ‘dark matter’
Recently, scientists are preparing to restart the Large Hadron Collider (LHC) in search of mysterious dark matter.
Scientists from the European Organization for Nuclear Research (CERN) are going to restart the “Large Hadron Collider”. It was closed for maintenance and improvement, but due to Kovid-19 it remained closed for a long time.
Dark matter is astronomical matter that neither absorbs, reflects, or emits light. For these reasons it becomes extremely difficult to identify it.
In addition, it also does not interact with the electromagnetic force. However, 80% of the universe is made up of dark matter.
The existence of dark matter is inferred only by the gravitational effect that it exerts on visible matter.
Dark matter is believed to provide extra mass to galaxies. This generates additional gravity, which is necessary to maintain their status quo. At the same time, visible matter is also called baryonic matter, because they contain baryons.
The baryons include; Protons, Neutrons and Electrons.
Large Hadron Collider (LHC)-
- The LHC is the most powerful particle accelerator ever built. It makes protons or ions move at the speed of light.
- It has a 27 km ring of superconducting magnets. It consists of several accelerator structures. These structures amplify the energy of the particles in the path.
- The accelerator is located in an underground tunnel of 100 meters at CERN.
- In the year 2012, it discovered the Higgs boson particle. This will help to understand why fundamental particles have mass.
