and boomerangs, all revolving through you and exploring the universe, making new discoveries just like you are.
As a result, dark stars would have been vastly larger and "fluffier" than normal Population III stars.
Computer simulations predict that dark stars can survive so long as the surrounding dark-matter density remains high.
The fate of dark stars once they run out of dark-matter fuel depends upon their mass.
Dark stars could thus explain how quasars--bright galaxies with supermassive black holes at their centers--existed only a few hundred million years after the Big Bang, sooner than most current theories predict.
Dark stars may also have played a role in ending the cosmic dark ages, a period of total darkness after the Big Bang when newly formed hydrogen and helium atoms absorbed all of the universe's light.
Lars Hernquist (Harvard-Smithsonian Center for Astrophysics) says dark stars would definitely have changed things.
For ultimate validation of their idea, the researchers hope the next generation of powerful telescopes will actually detect the dark stars, which could be 10 times as large as the solar system.
If these environments did exist, though, Hooper says dark stars could have existed.
Simon de Laplace later popularized Michell's early concept of a black hole - then termed a dark star - but abandoned the idea with the 1804 double-slit interference experiments of physician Thomas Young, establishing light as a wave function.
Sir Arthur Eddington, like Einstein, never could fathom the idea of a black hole - or Schwarzschild discontinuity as such a dark star had become known.
Liu suggested that dim dwarfs and completely dark stars
may account for a significant amount of dark matter in this galaxy, which lies in Draco.
