So Where Are They?

The Fermi Paradox poses the question, if intelligent ETs exist why haven't they shown up yet. Now a new mathematical study shows that self-replicating probes using sling-shot maneuvers (paper) could explore the entire galaxy in just 10 million years. Perhaps they're already here, hiding, waiting for our technology to reach a level that can de-cloak them.

New candidate for the Fermi Paradox

David Brin points to Asteroid belts at just the right place are friendly to life -November 6, 2012 , saying "This combination is calculated to be rare, in perhaps just 4% of solar systems. That rarity offers yet one more new, rather daunting candidate for the Fermi Paradox."

Is life on Mars a good sign for us?

The "Great Filter" is a hypothetical barrier to explain why civilisations are so unlikely to progress to the point of inter-stellar colonisation that we have not encountered any in 40 years of looking. Maybe humanity has already negotiated the filter - as some massive evolutionary improbability - or perhaps it lies in our future as an almost-certain threat to our existence? We should hold our breath as we look for evidence of life on Mars.
