In a new study, scientists have claimed that dark matter (the invisible matter) already exists in the universe even before the Big Bang. It is believed that 80 percent of the total mass of the universe is made up of dark matter. In a study published in the journal Physical Review Letters, researchers have presented a new idea based on astronomical hypotheses regarding the origin and identity of dark matter.

Dark matter affects galaxies

Tommy Tencannon, a post-doctoral fellow at John Hopkins University in the United States, have said that the study explores the new relationship between particle physics and astronomy. He said that if the dark matter exists in the form of new particles, which were born from the Big Bang, they also affect the galaxies. Tencannon said that through this relationship, they can be detected before the Big Bang.

Dark matter interacts through Gravitational effect 

Not much has been known about the origin of this substance yet, but according to astronomers, dark matter plays an important role in the formation of galaxies and clusters of galaxies. It is invisible. It cannot be detected directly, but its gravitational influence affects matter, planets, bodies, etc. in space.

Leftover after the big bang

Researchers speculate that dark matter is the residue after the Big Bang. Researchers also conducted long studies to detect this, but all experiments have been unsuccessful. Tencannon stated that if Dark Matter was indeed a remnant of the Big Bang, in many cases researchers should have already found direct clues to Dark Matter in various particle physics experiments, but they could not. This means that Dark Matter has already been present before the Big Bang.

What is dark matter? 

Dark matter is a hypothetical substance. Any substance can be detected by the radiation emitted from it, but dark matter cannot be detected by the radiation emitted. Its existence is estimated by its gravitational effects on visible substances. Scientists speculate that dark matter is composed of particles called neutralinos.

Universe formed from big bang

The universe was born as a result of a great explosion. Billions of years ago, the universe was in the form of an infinitely hot and dense object of size of a proton. At that time no concept like time and space existed. According to the Big Bang theory, a blast that occurred about 13.7 billion years ago emitted excessive energy. This energy was so huge that its effect can still be observed as the universe continues to expand even today. Everything we are able to see in the universe today is the result of Big Bang.
