Mysterious 'glue' holds planets, galaxies together.

CERN which is most powerful particle accelerator is now chasing ''glue" that holds our solar system, galaxies, and clusters of galaxies together  — dark matter.


A component of the universe whose presence is discerned from its gravitational attraction rather than its luminosity.

Dark matter makes up 30.1 percent of the matter-energy composition of the universe; the rest is dark energy (69.4 percent) and “ordinary” visible matter (0.5 percent).

According to CERN, dark matter is extremely hard to spot since it does not absorb, reflect or emit light and we have only been able to infer its existence from the gravitational effect it seems to have on visible matter.

Conseil Européen pour la Recherche Nucléaire (CERN),  is located on the French-Swiss border near Geneva.


In  last three years, the Large Hadron Collider has gone through maintenance and major upgrades which now equips it with the ability to operate at even higher energy and deliver significantly more data.

The restart of the Large Hadron Collider is crucial since the new upgrades will allow for acceleration of protons at higher energy and higher luminosity, which will in turn lead to more data.

Physicists not only just focus on dark matter but also study the subatomic particle W boson.
