If your civilization expands at a cubic rate through the universe, you can have one factor of linear growth for population (each couple of 2 has exactly 2 children when they're 20, then stop reproducing) and one factor of quadratic growth for minds (your mind can go as size N squared with time N). This can continue until the accelerating expansion of the universe places any other galaxies beyond our reach, at which point some unimaginably huge superintelligent minds will, billions of years later, have to face some unpleasant problems, assuming physics-as-...

That all sounds rather well, but sort of lights warning lights in the back of my head - that sounds suspiciously like an Applause Light.

My current issue would probably be regulation - it's possible this will all happen within a century. What if some superintelligent beings don't get to handle it in a few billion years? What if WE have to face it, with the less than rational people wanting to live as long as possible (We might want to too, but try to look over the consequences. Or I HOPE so at least), then what? I'm not asking what anyone else should do. I'... (Read more)(Click to expand thread. ⌘F to Expand All)Cmd/Ctrl F to expand all comments on this post

0shminux7y Due to my innate, if misguided, belief in the fair universe, I hope that everyone can get their own baby universe to nucleate at will. The mechanism [http://en.wikipedia.org/wiki/Eternal_inflation] has been proposed before: All these "unimaginably huge superintelligent minds" have to do is to control this process of bubbling.

One possible issue with radically increased lifespan

I might need a better title (It has now been updated), but here goes, anyway:

I've been considering this for a while now. Suppose we reach a point where we can live for centuries, maybe even millenia, then how do we balance? Even assuming we're as efficient as possible, there's a limit for how much resources we can have, meaning an artificial limit at the amount of people that could exist at any given moment even if we explore what we can of the galaxy and use any avaliable resource. There would have to be roughly the same rate of births and deaths in a stable population.

How would this be achieved? Somehow limiting lifespan, or children, assuming it's available to a majority? Or would this lead to a genespliced, technologically augmented and essentially immortal elite that the poor, unaugmented ones would have no chance of measuring up to? I'm sorry if this has already been considered, I'm very uneducated on the topic. If it has, could someone maybe link an analysis of the topic of lifespans and the like?
