And higher computational speed effectively seals you off from the rest of the universe. If you run your minds a million times faster, the speed of light becomes a million times slower from your perspective (about the speed of an airplane).<br>

Actually it's even worse. Downloading a small Web page from the far<br>
side of the planet currently takes about a second (optimally: light<br>
can circle the Earth about 7.5 times per second). One million seconds<br>
is 277.777... hours, which is a bit over 11.5 days.<br></blockquote><div><br></div><div>True.

Exploration by entire civilizations, or any group larger than an<br>
individual (or a collective small enough that they would all go<br>
explore together), generally involves a small number of scouts going<br>
forth and reporting back. That ship can't just "go explore"; it needs<br>
a way to send data back in reasonable time, or the civilization<br>
wouldn't build and send that ship in the first place.<br></blockquote><div><br></div><div>There are other reasons they might branch out aside from the goal of bringing back information (redundancy, protecting other planets, preventing self-replicators from taking over, etc.).</div><div><br></div><div>But once you get to the point of running minds on artificial substrates at greatly accelerated speeds, anything approaching interstellar distances is for all practical purposes, isolated and cut off (for seeming millions or billions of years or longer).
