Are ancient aliens ignoring us?

We’re obsessed with life beyond Earth.

For a while, we thought we might find it close to home. Venus turned out to be a hellish bust, and Mars is turning up nothing but red rocks. SETI has been beaming a hello for decades, but no one has greeted our call. So, unless you believe that Roswell is indeed the site of an alien vacation community, we’ve come up with nothing.

SETI

That hasn’t stopped us from making it a focal point of sci-fi and pop culture, from HG Wells’ vicious War of the star trekWorlds to the community of agreeable, and sometimes sexy, aliens embodied in the Star Trek series and movies.

And, the research to identify life supporting planets is going full steam, with hundred potential candidates identified to date. Now, we may be able to expand our time frame as well.

First, the title of this io9.com article — Freakishly Old System of Planets Hint at Ancient Alien Civilizations — is misleading. Nowhere does the writer, or the research, state that we’ve found any kind of proof (or even a hint) of alien life.

But what we’ve discovered—that rocky planet systems are billions of years older than we first thought—is intriguing in its implication. And what is this implication? That life, and advanced civilizations, have had several billions of years in which to develop.

Our universe is considered to be about 13.8 billion years old, and according to the article, scientists have detected a planet system that is about 11.2 billion years old. Before this, scientists didn’t believe that rocky planets capable of sustaining life could have formed that early in our universe’s life span. Now they know different.

But this leads to the inevitable question: if there are so many planets that could potentially support life, and if these planets have existed for at least 11 billion years, then why isn’t our universe teeming with life? Surely there would be ONE advanced civilization that would have colonized the stars. Was there NEVER a planet capable of supporting life? Or, did they ALL fail to advance to the point we have?

Revelation_Space_cover_(Amazon)One of my favorite sci-fi writers, Alastair Reynolds, explored this very topic in his book Revelation Space. His world view was bleak: advanced civilizations destroyed each other, leaving behind a higher power that would snuff out advanced civilizations whenever they reached the point of breaking their planetary bounds.

If that’s true, then we’re in danger.

Or, maybe there are tons of aliens out there, and they don’t find us interesting enough to return our calls.
