The Unexplained Missing Matter Of The Universe

By Sourav Ghosh - August 03, 2018

Crowded with thousand million mysteries, the Universe has been baffling us from the beginning, making a never-ending journey of our intellection. And along with its unexplained Dark Matter and Dark Energy, our universe holds another huge part of its mystery called the "Missing Baryonic Matter" that also leads a big question to our present science.


Approximately 96 percent of the Universe is filled with Dark Energy and Dark Matter, and the Regular Matter is making up the rest 4 percent. A Regular Matter is everything which we can see or observe, that means from the micro dust particles to the large galaxies all are being in this Regular Matter category. But, researchers were puzzled to find that more than half of this Regular Matter which is approx 2.5 per cent of the Universe is totally missing. This missing matter is best known as the Missing Baryonic Matter, and it's mainly made of particles such as protons and electrons that make the maximum of the mass of the Universe's visible things or Regular Matter.


A baryon is the unit of Baryonic Matter that is a composite subatomic particle made up of three quarks – a triquark, as distinct from mesons, which are composed of one quark and one antiquark. Actually, all the Regular Matters that may be encountered or experienced in everyday life are Baryonic Matter. But, what's about the missing matter or so-called Missing Baryonic Matter??

Since the last two decades, many astrophysicists have explained that the missing Baryonic Matter may be found inside galaxies, in the material which known as the warm-hot intergalactic medium, however, the Universe's missing baryons remain a hotly controversial topic till this day.


According to the new research of two separate teams – one was led by Hideki Tanimura, held at the Institute of Space Astrophysics in Orsay, France, and the other team was led by Anna de Graaff, held at the University of Edinburgh, UK – they have found the missing matter which is catenating galaxies together through the invisible filaments of slightly hot, diffused gas.

Due to being so ethereal and not quite hot enough for the X-ray telescopes to pick up, nobody has been able to see it before. So that, the two research-groups had to search out another way to definitively conclude these threads of gas do really exist there.


Both teams have followed the systematic rule of a phenomenon called the Sunyaev-Zel’dovich effect that occurs when light left over from the big bang goes beyond through hot gas. As the lights travel, some of it diffuse off the electrons in the gas that leaves a petit patch in the cosmic microwave background which indeed indicates its existence there.

However, there is no suitable spot or instrument that we have invented yet to observe these threads of gas instantaneously, and the Missing Baryonic Matter is been completely a speculation until now.
