 IS DARK MATTER OLDER THAN OUR UNIVERSE  ?

Dark matter is major contributer for mass distribution, nearly 85%of universe mass. Dark matter is formed mostly in cosmic expansion time after Big Bang. 

According to new studies, scientists believed like dark matter is older than universe. New studies showed that dark matter started to formed, when space was expanding very fastly.The constitution of Dark matter most mysterious elusive . 

The study published in physical review letters presents how dark matter was formed and how it might be identified in coming decades during astronomical experiments. 

A new Johns Hopkins University study suggests dark matter may have existed before the Big Bang. 

"This new study shows relationship between particle physics and astronomy.  "

says Tommi Tenkanen, a postdoctoral fellow in JHU’s Department of Physics and Astronomy and the study’s author. “If dark matter consists of new particles that were born before the Big Bang, they affect the way galaxies are distributed in the sky in a unique way. This connection may be used to reveal their identity and make conclusions about the times before the Big Bang, too.”

It is tough to detect dark matter but scientists believed that it shows its effect by it's gravitation . It gives shape to galaxies and direction to them. For long time, scientists believed that dark matter is byproduct of Big Bang, but new studies it may be wrong. Scientists have long sought this kind of dark matter, but so far all experimental searches have been unsuccessful.

If dark matter were truly a remnant of the Big Bang, then in many cases researchers should have seen a direct signal of dark matter in different particle physics experiments already,” Tenkanen says.

Scientist have performed so many experiments to examine it as byproduct but it failed many times. 

Using a new, simple mathematical framework, the study shows that dark matter may have been produced before the Big Bang during an era known as the cosmic inflation when space was expanding very rapidly. The rapid expansion is believed to lead to copious production of certain types of particles called SCALARS So far, only one scalar particle has been discovered, the famous Higgs boson.

“We do not have idea what dark matter is, but if it has anything to do with any scalar particles, it may be older than the Big Bang,” Tenkanen explains. “ We don’t have to assume new types of interactions between visible and dark matter beyond gravity, which we already know is there,if we assumed a new mathematical results. 

"The idea of dark matter existed before Big Bang is not new but other scientists are unable to come up with mathematical conclusions 

This shows scientists have overlooked simplest mathematical scenario. "he says. 

The study also suggests a way to test the origin of dark matter by observing the signatures dark matter leaves on the distribution of matter in the universe.

“While this type of dark matter is too elusive to be found in particle experiments, it can reveal its presence in astronomical observations,” Tenkanen says. “We will soon learn more about the origin of dark matter when the Euclid satellite is launched in 2022. It’s going to be very exciting to see what it will reveal about dark matter and if its findings can be used to peak into the times before the Big Bang.
