  Dark star (dark matter)
  
  A dark star is a hypothetical type of star that may have existed early in the universe before conventional stars were able to form and thrive. Properties The dark stars would be composed mostly of normal matter, like modern stars, but a high concentration of neutralino dark matter present within them would generate heat via annihilation reactions between the dark-matter particles. This heat would prevent such stars from collapsing into the relatively compact and dense sizes of modern stars and therefore prevent nuclear fusion among the 'normal' matter atoms from being initiated. Under this model, a dark star is predicted to be an enormous cloud of molecular hydrogen and helium ranging between 1 and 960 astronomical units (AU) in radius; its surface temperature would be around 10000 K. It is expected that they would grow over time and reach masses up to 10 ...
