This invisible ordinary material located in galactic filaments thanks to ultra -fine influence intrigues scientists

For decades, part of the ordinary matter of the universe was not found. For example, Thanks to brief radio starts from distant galaxies, scientists have finally managed to locate it. Furthermore, And their discovery changes our vision of the universe.

The missing ordinary material hides in the intergalactic vacuum

When we think of the matteron imagine les planetsTHE. Therefore, starsor our own body. However, this matter called ordinarycomposed of protons and this invisible ordinary material located neutronsonly constitutes 5 % of the universe. Furthermore, The rest is divided between the dark matter (27 %) and theblack energy (68 %), two entities still mysterious.

But another problem. Nevertheless, intrigued researchers: even these 5 % ordinary matters did not seem entirely present. In addition, About it Half was missing. For example, It was not or in the galaxies nor in starswhich had posed a serious challenge to scientists for the years 1990.

For what ? Because this material adopted a form very difficult to detect. She was scattered in the form of Hot and diffuse gas in the gigantic Cosmic filamentsbetween galaxies. Nor X -rays nor the ultraviolet were not able to reveal it. The instruments remained Blind to this cosmic fog.

Of the Ultrarapid radio starts reveal the matter scattered this invisible ordinary material located between the galaxies

This is where the FRB (Fast. Radio Bursts) enter the scene. These Radio lightningbrief but powerful, come from distant galaxies. They cross the universe in a straight line, except when they meet material clouds. So they slowly slow down.

Researchers from Center. for Astrophysics had a brilliant idea: measure this slowdown To estimate the amount of material crossed. They studied 60 FRB from distances up to 9.1 billion light years. By analyzing their trajectories, they were able to Cartographing invisible baryonic material.

The result is striking: 76 % of ordinary material is in the intergalactic environment. THE Galaxies halos contain 15 %while the stars and the visible gas only shelter 9 %. In short, thevast majority Ordinary matter escaped us.

According to Vikram ravione of the authors of the study, these this invisible ordinary material located FRB work like Cosmic tracers. They reveal a structure invisible who weaves the universe. This work is not limited to a simple census. It also shows how the universe self -regulating : when too much matter accumulates in a galaxy. the energy of supernovae or black holes Projected it to theintergalactic space. And Dynamic and fascinating balance.

A New cosmic cartography sketches thanks to future radio stakescopes

Thanks to this method. researchers redraw the contours of the cosmos. What we thought videbetween galaxies, is actually a subtle gas network. This structure – nicknamed cosmic canvas – connects all the visible elements of the universe.

And this is only the beginning. Instruments like CHIME. HIRAX or the future DSA-2000 promise multiplier ces observationsd’refermaybe even to better understand the dark matterby studying his Interactions with the this invisible ordinary material located bars.

For the moment, this discovery is enough to change our perspective. The lost ordinary matter has never disappeared. She was just Hidden in the invisible folds of the cosmos.
