Study Suggests Dark Matter Planets May Exist Out There

In this video Anton discusses a theoretical paper exploring the concept of "dark exoplanets" - hypothetical planets made of dark matter. Assuming dark matter is composed of physical particles, the study investigates the potential existence and observable properties of these exoplanets. Scientists consider two types of dark matter: extremely small particles and composite dark matter, made of larger chunks. Detecting these exoplanets may be challenging, as they could produce different shadows during transit and have unusual mass or size profiles. The study suggests that extremely dense or low-density planets, and planets that gravitationally affect a star but don't produce transits, could be signs of dark matter. The research provides groundwork for further analysis, but more data on dark matter is needed.
