Fast moving neutron star

From NewScientistSpace.com:<ul type="square"><b>Neutron star clocked at mind-boggling velocity</b><br /><br />A neutron star has been clocked travelling at more than 1500 kilometres per second. It joins the ranks of other fast moving neutron stars, deepening the puzzle over how these dense stellar corpses are accelerated to such astonishing velocities.<br /><br />Neutron stars are the city-sized spheres that remain after stars are destroyed in supernova explosions. They are incredibly dense – a teaspoonful of neutron star material would weigh a billion tonnes. <br /><br />Many neutron stars are now known to travel at speeds of hundreds of kilometres per second, with one shown in 2005 to be moving at 1100 km/s (see Fastest pulsar set to escape the Milky Way). Some others have been estimated as travelling faster than 1500 km/s but with less certain measurements: their speeds were measured in an indirect way, based on observations of their effect on the gaseous medium that they move through.<br /><br />Astronomers have had a hard time figuring out how neutron stars get accelerated to such blistering speeds. Their theoretical models can produce speeds of a few hundred kilometres per second, but these suggest that neutron stars should rarely, if ever, reach more than 1000 kilometres per second.<br /><br />The neutron star now found to be zipping along at 1500 km/s is providing an even bigger challenge for the models. Its speed was measured by Frank Winkler of Middlebury College in Vermont and Robert Petre of NASA's Goddard Space Flight Centre in Greenbelt, Maryland, both in the US. <br /><br />...

As one may know: Nuetrons can't last very long without protons....<br /><br />Maybe since electrons and protons are collapsed into nuetrons.... possibly deep in side the nuetron star a strange phenomenom takes place in which the immensce gravity have caused tiny microscopic black as these black holes produce antimatter. This anti matter then also turns into anti nuetrons.<br /><br />Is it possible the immense gravity could keep the anti matter from re- acting...?<br /><br />Any way ... as a result this probably produces an immense magnetic field that actualy pull electrons to the north pole and positrons to the south blasting these tiny par ticles out...<br /><br />Then it is possible that these partticles seek ech othe out, meeting half way and exploding<br /><br />Also this would not be a firey explosion just a huge elecrtromagnetic jet that would possibly propel the object at high speed...<br /><br />Something like an Ion Drive I would think.....?<br /><br /><br /><br /><br /><br /><br /><br /><br /><font color="yellow"> Oh yeah...By the way.... I was making this all up....just brainstorming.....haven't the slightest idea if any of this is true.... <img src="/images/icons/laugh.gif" /></font> <div class="Discussion_UserSignature"> <div>________________________________________ <br /></div><div><ul><li><font color="#008000"><em>your move...</em></font></li></ul></div> </div>
