Dark star
In “From Dark Matter to Light: New models of galaxy formation show the gastro in physics” (SN: 3/22/08, p. 186), Ron Cowen says that gas is where the action is since dark matter predominantly responds to only gravity. Because dark matter responds to gravity, wouldn’t it, like gas, be pulled into the star-making process and become part of the resulting star? Why is our sun not predominantly dark matter?
