For a long time, scientists have declared that we are surrounded by dark matter and dark energy which helps in binding the galaxy together. Yet they have not been able to spot them directly. Liano Wang who researches on finding signals in large particle accelerators at LHC and a physics professor at the University of Chicago says that they are confident that there is a dark world where the energy is powerful than ours.

Researchers from the University of Chicago and the university affiliated Fermilab have reported the findings in Physical Review Letters. They have found a creative way of tracing dark matter. They separate the dark particle which they see frequently interacting with normal matter. Researchers estimate that the particles which aren’t yet discovered are big and have longer life span than the particles which are already discovered. Researchers know that the particles can be easily caught when the LHC creates the collision and the number of collisions is measured.

95% or above of the universe is made of the dark world and scientists know it from the effects it creates. The effects are just like supernatural activities we can see it only when something unnatural happens. For example, we know there is a dark matter when we see all galaxies held together and gravity doing its work.

According to the previous research on the working pattern of the universe, Wang said that the particles which have a longer lifespan are somewhat related to Higgs Boson and they are the doorway to the dark world and the Higgs can decompose into these particles. So the problem here is how to rectify the events from all the other events since its very difficult to find out the particles after a collision because more than a billion collisions take place within a second and the subatoms gets scattered in every possible direction. 

Lin said that if it’s heavier then it would fetch the energy to be produced and so the momentum would be low and it would move slower than the speed of light. Researchers can easily twist their algorithm to separate particles that have a longer life span and decompose slower than the remaining subatomic shrapnel. Scientists search for the time difference of less than a billionth of second and they are optimistic towards the LHC censors that they are responsive enough to complete the job. LHC instruments are being updated so that when the collider attacks take place in 2021 they search for the slowly decaying particles.
