Rogue planets could outnumber the stars
I think it&#x27;s kinda cool to consider that rogue planets &#x2F; brown dwarfs [0] could be candidates for extending human life beyond the solar system post-Sol. Assuming we have enough fissile material (or master cold fusion) to perpetuate the civilization&#x27;s energy requirements, we could explore the stars in darkness for eons.<p>I&#x27;m not sure how likely they are as candidates for life to emerge spontaneously, it seems like there&#x27;s a very high energy input requirement over billions of years (Sol -&gt; Earth) to get anything close to human civilization... but it&#x27;s cool to think that, perhaps, some future humans could settle a planet eternally cloaked in darkness. Adapt to the reality of that planet over generations... and be unable to acclimate to life near stars at all.<p>Also, post-Andromeda collision, is this a <i>necessary</i> future for posthuman life? [1] Billions of cold worlds will be flung into the far reaches of the Universe.<p>[0] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Brown_dwarf" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Brown_dwarf</a><p>[1] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Andromeda–Milky_Way_collision" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Andromeda–Milky_Way_co...</a>
