"dark stars" theory could solve universe's greatest mystery

The "dark stars" theory posits that the universe's first stars formed from dark matter, potentially explaining large black holes' origins. Recent observations suggest possible dark stars, while axions may form detectable axion stars.

"dark stars" theory could solve universe's greatest mystery

The theory of "dark stars" proposes that the first stars in the universe were massive, invisible entities formed from dark matter, potentially providing insights into the elusive nature of dark matter itself. These stars, theorized to be composed of weakly interacting massive particles (WIMPs), would not undergo nuclear fusion like ordinary stars but could still emit heat through dark matter interactions. This concept may also explain the rapid formation of large black holes in the early universe, which could have originated from the collapse of WIMP stars. Recent observations using the James Webb Space Telescope have identified three distant objects that might be dark stars rather than galaxies, although distinguishing them requires advanced spectroscopy techniques. Meanwhile, interest is growing in axions, another potential dark matter candidate, which could form axion stars that are stable yet difficult to detect. These axion stars might explode in a phenomenon called a "bosenova," producing low-energy photons detectable by future radio telescopes like the Square Kilometre Array. This research could significantly advance our understanding of dark matter and the early universe.
