Researchers made a stupefying discovery that could advance the field incredibly. The mind-blowing finding relates to finding the place where five percent of the Universe’s baryonic matter had been concealing.
Dark matter, an element that has mass and also occupies space, is believed to exist in a percent of 85 out of all the matter found in the Universe. However, this cannot be explained; hence, it gets its name because it doesn’t seem to react with visible electromagnetic radiation, such as light. Therefore, it is unidentifiable by today’s astronomical technologies.
It’s Been Finally Discovered
Almost all matter that may be contended or experienced in daily life is known as baryonic matter, which comprises atoms of every kind, supplying them with the property of mass. This type of dark matter is made out of baryons, which are heavy subatomic particles like protons and neutrons and a mix of these, as well as non-emitting common atoms that are making it more visible.
Until not long ago, researchers had no knowledge whatsoever regarding where this originated, but Amazon’s Prime New Frontiers in Space unveiled how that all took a different turn back in 2018.
Presenter Julian Huguet said that they could not find the common baryonic matter, ‘like you and me and everything we know;’ the matter that composes less than five percent of the Universe.
“That’s not to say we didn’t have a pretty good idea of where it was, the matter we could account for was where you would expect it to be, bundle up in two trillion galaxies, each with an average of hundreds of billions of stars across the Universe.
“In between these galaxies, we think there are fragments of dark matter linking them together in a mind-breakingly huge cosmic web.
“We suspected the gravity of that dark matter also attracted regular matter too, which had been turned into plasma after ultraviolet radiation from early stars separated atoms from their electrons,” he explained.
It Must be Interacting With Other Kinds of Matter
The presenter proceeded to explain how the discovery was made. The plasma that’s been created is known as WHIM or warm, hot intergalactic matter, and for a rather extensive period, scientists were not able to see it because it was incredibly difficult to detect.
Then, two separate teams of researchers found it utilizing the Sunyaev-Zel’ doviich Effect. When two photons travel through a plasma, they get leveled to a somewhat higher energy rank. The impact is, however, incredibly tiny, so the teams used data from hundreds of thousands of millions of galaxies they believed would be connected by WHIM.
“They stacked them up until the effect was noticeable and, just like that, they found half the baryonic matter in the Universe and more evidence of a dark matter web. So we are five percent down, only 95 percent to go – we’re getting closer,” Huguet explained.
More scientists believe that dark matter is abundant in the Universe, and that is has a powerful effect on its structure and development. This showed up from measurements suggesting that a number of galaxies would fly apart, or they would not have taken a form or would not have traveled the way they currently do if they did not have a massive amount of invisible matter.
Dark matter has not yet seen directly, so if it present in the Universe, it must hardly interact with common baryonic matter and radiation.
