Dark Matter "Nuggets" May Light Up Milky Way, Scientists Propose Bold Theory

• Scientists detect an unexplained ultraviolet glow spread across the Milky Way galaxy, which cannot be attributed to known sources like stars, gas, or dust.
• A new, controversial theory suggests hypothetical "axion quark nuggets" – dense, microscopic dark matter objects containing antimatter – are responsible.
• These dark matter nuggets could glow by releasing far ultraviolet radiation when their antimatter collides and annihilates with ordinary interstellar material.
• Simulations based on this theory surprisingly match excess ultraviolet light measurements from multiple space missions, offering potential observational evidence for dark matter.
• While unproven, confirmation of this hypothesis would revolutionize cosmology and particle physics, providing the first visible signals of dark matter's presence.

Why It Matters: A bold theory proposes dark matter "nuggets" cause the Milky Way's mysterious ultraviolet glow.
