A new hypothesis suggests that dark matter is composed of different types of particles
An article published in the Journal of Cosmology and Astroparticle Physics suggests that dark matter may be more diverse than previously thought. A new study suggests that dark matter could be composed of multiple components that behave differently in dwarf galaxies. Credit: ESA The nature of dark matter is one of the main open problems in cosmology, as it is not directly observed but only through its gravitational effects. Evidence includes gal…
Sometimes, in astrophysics, what you don't see is more revealing than the brightest signal. Absence can become a major clue, forcing scientists to rethink their certainties.
At the heart of the Milky Way, a mysterious excess of gamma rays has captivated astronomers for more than fifteen years. A new revolutionary study proposes that black matter should not consist of a single particle, but of two — an explanation that finally reconciles the contradictory observations of the galactic center and the dwarf galaxies.

Scientists think dark matter might come in two forms
Dark matter may come in two flavors—finally explaining why its signals appear in some galaxies but vanish in others. A mysterious glow of gamma rays at the center of the Milky Way has long hinted at dark matter, but the lack of similar signals in smaller dwarf galaxies has cast doubt on that idea. Now, […] The post Scientists think dark matter might come in two forms appeared first on Science Tech Updates.
