The Dead Head Thread (OT and Not)

Dark stars are something of a misnomer - unlike dark matter particles, they would be visible and actually quite bright because they would still mostly be made of regular matter. In fact, the dark stars would have been the brightest bodies in the young universe, as the constant annihilation of dark matter particles would release massive amounts of energy. The star would burn through its dark matter nucleus very quickly, and then a new nucleus of normal matter would form, starting up the more familiar nuclear fusion process inside the star. It's possible these former dark matter stars are still around in the modern universe.
