Exploring the Mystery of Invisible Boson Stars and Dark Matter

Scientists are probing the intriguing world of "boson stars," theorized celestial bodies made of a proposed form of dark matter. This exotic matter potentially accounts for about 25% of the universe's mass and energy, though it remains largely undetectable. For years, researchers pursued weakly interacting massive particles (WIMPs) as candidates for dark matter, but failed to uncover direct evidence.

An alternative candidate, the axion, was introduced to resolve discrepancies in the strong nuclear force theory. Axions, if they exist, would not only be extremely light—far lighter than known particles—but could also exhibit unusual behaviors across galactic spans. Their properties enable them to form dense structures resembling stars, which may go unnoticed due to their lack of light and minimal interactions with normal matter.

These invisible stars, also referred to as axion stars or dark stars, pose a challenge for detection but could reveal themselves through effects on nuclear reactions or other cosmic processes. While the existence of axions and boson stars remains theoretical, the pursuit of understanding dark matter continues to captivate physicists and astronomers alike.
