Dark matter probably accounts for a whopping 80 percent of the mass of the universe. But this single fact is the extent of our knowledge of this mysterious, pervasive substance, with scientists not knowing exactly what it is and how it came about. Now a groundbreaking study has revealed that dark matter can be even more bizarre than first thought, since its origin actually dates to the beginning of the universe, the Big Bang.
Dark matter is difficult to understand because it is not direct
Scientists know that dark matter dominates ordinary matter in the universe more than five times.
This is because galaxies rotate too fast to hold on to their stars.
Without this dark matter holding them together, the laws of physics say that these galaxies will disintegrate.
The Milky Way rotates so fast that it must contain 30 times more dark matter than ordinary matter.

Tommy Tenkanen, a doctoral student in physics and astronomy at Johns Hopkins University and author of the study, believes he has found a new connection particles and astronomy.
He said: "If the ark matter consists of new particles that were born before the Big Bang, they affect the way galaxies propagate in the sky in a unique way.
"This connection can be used to reveal their identities and to draw conclusions about the times before the Big Bang, too. "
The shocking findings contradict the long-held assumption that dark matter is a remnant of the Big Bang.

Mr Tenkanen adds: "If dark matter was indeed a remnant of the Big Bang, then in many cases the researchers would have seen a direct signal of dark matter in various particle physics experiments."

Dark matter would be born during the age of space inflation, when space time anded at unimaginable speeds.
It is believed that this expansion leads to the introduction of parts of the fad.

Mr Tenkanen added: "We don't know what it is, we don't know what it is but if it has anything to do with any scalar particles, it may be more – Old by the Big Bang.
"With the proposed mathematical scenario, we do not need to accept new kinds of interactions between visible and dark matter beyond gravity, which we already know to be. "
The astrophysicist thinks that the potential sign results have been missed so far, because scientists have neglected the simplest possible mathematical scenario for the origin of dark matter.
And research could even lead to a new method of testing theory by observing dark matter with the signatures it leaves on the distribution of matter in the universe.
