What is the significance of Neutron Stars in the game setting?

I was just downloading a copy of the map that Jacobsar updated with the location of the Ebony Eyes twin black hole system to the Port Loren Public Library.<br /><br />I happen to notice an abundance of neutron stars on the map. Hence the question in the title<br /><br />wikipedia has interesting facts about them:<br />http://en.wikipedia.org/wiki/Neutron_star<br /><br />stuff like they have a mile thick crust and a 1m deep atmosphere, an escape velocity of 33% of light speed-yeow! combine that with the high levels of x-ray radiation and you deffinetly dont want to get too close.<br /><br />Anyway I'm not looking to plumb the depths of why they exist in our universe but rather why do they exist in the SF universe.<br /><br />Are they there as impassible terrain or is there the possibility of using a neutron star or a binary neutron star as a setting for adventure? (most likely KH style adventure unless a science ship is in wide orbit to observe a binary neutron star grabbing enough matter from an orbiting star so that it collapses to a black hole.)<br /><br />Why should the map be loaded with so many neutron stars?<br />Is that an unusual concentration of them?<br /><br />
