Von Neumann Machines - or Self Replicating Probes....

“........And indeed, these probes would be remarkably efficient. A recent study published in the International Journal of Astronomy pointed out that extraterrestrial intelligences (ETIs) could use the slingshot effect to propel SRPs from star to star. And yes, that's the same method used to propel the Voyager spacecrafts through our solar system from planet to planet. For it to work on a galactic scale, however, SRPs would use slingshot maneuvers around stars, gaining a boost in velocity by extracting energy from each star's motion around the galactic center. The slingshot effect would carry little-to-no extra cost and result in a 100-fold increase in efficiency; models show that this technique could be used to send probes to every solar system in the galaxy in as little as 10 million years......”
