Comment 26 by Steve Zara : . Even an incredibly slow process of colonisation would have filled the galaxy on a timescale of millions of years, because of the exponential nature of growth. If any culture had launched replicating probes, they would be here because they would be everywhere.

I'm curious Steve, why would it necessarily have to be exponential growth? Couldn't there be extenuating circumstances (of what I'll admit to not knowing) that would prevent such growth?
