New Study Proposes Dark Matter May Have Existed Prior to the Big Bang

A new mathematical model indicates that dark matter may have formed before the big bang during the rapid expansion of cosmic inflation.

Scientists from the Johns Hopkins University think that dark matter could have existed before the Big Bang and offers fresh approaches towards its identification. Using a concept that has just emerged in the theory of dark matter the work suggests that dark matter could have been created during the phase of cosmic inflation, scalar particles such as the Higgs boson being in sight. This theory was not expected since the earlier concept regarding dark matter was that it was formed at the time of Big Bang. The study also describes how one could track the influence of dark matter on galaxy distribution in an attempt to decode the state of the universe before the big bang. Perhaps the Euclid satellite mission in the coming future will shed some light on this issue even more.

Dark matter is calculated to account for about 80% of the universe’s mass, yet it is probably the most mysterious of all forms of substance. A recent research done at Johns Hopkins University recommend that dark matter could possibly have predated the Big Bang.

Presented in Physical Review Letters this work presents a new conjecture on the production of dark matter and how the existence of that matter might be credibly inferred from astronomical data.

“The study adds a new piece to the connection between particle physics and astronomy,” said Tommi Tenkanen, now a post-doctorate fellow in the Department of Physics and Astronomy at Johns Hopkins. “If dark matter had particles which existed before Big Bang then its effect on the distribution of galaxies would be distinctive and could point to the particle’s identity as well as the existence and nature of the particle before Big Bang. ”

Despite that the nature of dark matter is not so clear, its major contribution to galaxy and cluster formation is well understood. But the matter in dark classes is not directly detectable and this fact is deduced from the influence it exerts on the normal matter.

Earlier, dark matter was postulated to be a residue of the Big Bang and many experimental searches had been done previously.

“Were dark matter a relic of the Big Bang, we should have been already pinpointing direct signals in the particle physics experiments,” Tenkanen opines.

The work uses a brand new, simple, analytical scenario that the dark matter might have been created during the cosmic inflation prior to the big bang. This expansion possibly created many scalar particles and until now only the existence of Higgs boson in the group of scalar particles has been established.

“As for what it is, we do not know to this day, but if dark matter does have something to do with scalar particles, then it may be even older than the singularity of the Big Bang,” Tenkanen expounds. “This appears in a new model that gets rid of novel types of interactions between luminous and dark matter other than gravity. ”

In one way, the idea of pre-Big Bang dark matter is not exceptional however earlier hypotheses did not have quantitative calculations. This research postulates that perhaps scholars have failed to pay attention to other basic statistical patterns to explain the formation of dark matter.

The work also presents a method of detecting if dark matter formed in the early universe by looking at the impacts of such a substance on matters distribution in the largescale universe.

“It may be practically impossible to observe this type of dark matter in particle experiments but it may be seen through astronomical methods as Tenkanen reiterates. “As newcomers Euclid satellite to be launched in 2022 will be promising in studying dark matter and can give a clue to the state before time began. ”
