The Milky Way is again in the midst of a stunning discovery after scientists offered for the first time an explanation as to why the center of our galaxy glows. According to a theory formulated by scientists, the glow we see in the center of the Milky Way galaxy would be based on the annihilation of the black matter that would be there, and this is the first time such information has been presented by them.
According to the theory, dark matter particles would collide with each other in the central area of the Milky Way galaxy, and this would form both elementary particles and gamma rays, which are then thrown through the galaxy. The bright light source, which is called the excess from the galactic center, was discovered in the central area of the Milky Way in 2009, and until recently it was studied in order to discover what exactly is at the basis of its existence.
The Milky Way: Major Discovery, Why the Center Shines
The Milky Way is vast, and the region where these collisions between dark matter particles are recorded is very large, but even so, it took over a decade of analysis to arrive at this theory. According to scientists, when dark matter particles collide, they disintegrate and lead to the formation of electrons and positrons, the process being able to be reproduced including on Earth, not just in the Milky Way.
"I think the most interesting finding is that dark matter can explain the galactic center excess. This result has never been found with a model where everything, the dark matter density and the particle physics model, are taken consistently."
Of course, this theory is supported by some scientists, while others do not agree with it, and say that in fact the glow from that area of the Milky Way galaxy would have other sources. We're talking about what they call millisecond pulsars, or other types of stars, so no one knows 100% for sure what exactly is going on there, but theories will continue to emerge in the absence of 100% clear data about that region of the Milky Way .
The Milky Way is monitored from a distance by researchers, and this is because no one has managed to get too close to the center of the galaxy, and more than likely will not, considering how far it is.
