What is the proposed primary energy reservoir for Dark Stars?

Answer

Dark matter annihilation or decay

The foundational concept differentiating Dark Stars from conventional stars is their power source. While typical stars rely on the finite process of fusing lighter elements like hydrogen into helium within their core, Dark Stars hypothetically use energy derived from the interaction of dark matter particles accumulated within their center. Theoretical models suggest that when enough dark matter particles accumulate, they either annihilate each other or decay, releasing substantial energy. This sustained energy output provides the necessary outward pressure to counteract gravity, effectively replacing the limited thermonuclear energy derived from burning nuclear fuel, thereby allowing the star to exist for timescales far exceeding the age of the universe.
