Dark substance is thought to create up around 26 percent of the known Universe, but no one in fact knows what it is, what it’s complete of, or how to detect it.
Like the 'normal' substance that we see in stars, humans, slime, and all else in the cosmos, dark matter appear to exert a gravitational force, but it doesn’t emit any form of light or emission that scientists can notice. It’s as if the Universe is being haunted by the majority pervasive ghost ever - we can feel its attendance, but we don’t have the right gadgets to catch it in the act.
Currently an astrophysicist at NASA says he might be able to explain why our present models of the Universe require something like dark substance to exist, but we can’t find it, no matter how hard we try: dark matter strength consist of the massive black holes that appeared within a fraction of a next after the Universe first come to be.
The survival of these so-called primordial black holes could have indistinct the distribution of mass in the near the beginning Universe, says Alexander Kashlinsky from NASA's Goddard Space Flight Centre, which is something we’ve been annoying to explain through the survival of hypothetical high-mass particles such as Weakly Interacting Massive Particles (WIMPs) and axions for decades.
But every trial so far, such as NASA's Alpha Magnetic Spectrometer and Fermi Gamma-ray Space Telescope mission, has failed to turn up proof that these particles in fact exist.
"These studies are as long as increasingly sensitive consequences, slowly decrease the box of parameters where dark stuff particles can hide," says Kashlinsky. "The breakdown to find them has led to renewed interest in study how well primordial black holes - black holes formed in the Universe's first part of a second - could work as dark matter."
Back in 2005, Kashlinsky and his team second-hand NASA's Spitzer Space Telescope to get a snapshot of the background glow of infrared light in a sure region of space. This snapshot came to be known as the cosmic infrared background (CIB).
"This study is an effort to bring jointly a broad set of ideas and observations to check how well they fit, and the fit is surprisingly good," says Kashlinsky. "If this is right, then all galaxies, including our own, are fixed within a vast sphere of black holes every about 30 times the Sun's mass."
The hypothesis has been outline in The Astrophysical Journal Letters.
Only more evidence from prospect LIGO experiments can strengthen or refute it, but until then, it might be time to put in primordial black holes to the list of dark matter candidate.
And if Kashlinsky is right, then dark matter truly was beating right under our noses this whole time - the darkest the majority mysterious thing in the Universe is the darkest the majority mysterious thing in the Universe.
