<div dir="ltr"><div>Just a little comment. When in the sessions of sweet silent thought I mused over the Von Neumann probe notion, pondering the hows and whys of such a "colonization" effort, I envisioned the probe as the tiniest little beastie. You know, ultra-low mass, speeding along as close to the speed of light as possible. How then to deal with the deceleration issue? How to put the probe, or associated payload down on the stepping-stone planet in that far away solar system? How to effect the self-replication essential to a Von Neumann probe colonization effort? Well, here we see a limited class of solution.</div><div><br></div><div>In the case of a highly Advanced technological civilization, the Von Neumann probe merely has to send down the appropriate digital package to hijack some of the extant resources on the planet below. As it approaches such a planet, it evaluates the level of Technology, and prepares the hijack package. Then a flyby is all it takes.</div><div><br></div><div>Then, it's either an assault by grey goo to overcome defenses, or something more subtle.</div><div><br></div><div>In the case of an uninhabited, or pre-industrial planet however, the deceleration issue remains. </div><div><br></div><div>Best, Jeff Davis</div><div><br></div><div class="gmail_signature"><div dir="ltr"> "Everything's hard till you know how to do it."<div> Ray Charles</div></div></div>
