THE NO LIFE OUT THERE IDEA
If you’re going “Enough with life on Mars”, I’m sorry.
Seriously!
I know there’s too much not finding life going on.
You lost interest in life-finding years ago, right? But who cares? We keep not finding it, right?
Recently, we didn’t find it on Mars. Also, we recently didn’t find it on Titan or on Europa or on Io.
Not to mention the exoplanets, planets circling other stars, where, it so happens, we also haven’t had much luck. Plus, very excitingly, we now know there’s a dwarf planet called Ceres. Ceres is fairly warm, probably has oceans full of water and isn’t that far away.
We didn’t find life there too.
Not finding life is pretty much everywhere these days and, you know what? We’re just starting.
No life out there? Don’t get used to it
I hate to squash the hopes of the “Not Lifers” but things don’t look that good for them, in the long run. The Mars rover, Curiosity, has finally made it to Gale Crater where it has analyzed the rocks and found organic molecules and “puffs” of methane. Organic molecules are (often) a sign of life. Puffs of methane? Same thing (although that isn’t for sure either). Philip Gillet (Earth And Planetary Sciences Laboratory) says a meteorite from Morocco (but once from Mars) has organic chemistry that is “probably” biologic.
While these latest discoveries may turn out to be another Didn’t Find It Moment, that can’t go on forever. Sooner or later – sooner, in my opinion, we will find a microbe somewhere – somewhere besides our own silly planet.
Unless something unmistakably alive walks by one of our cameras, we probably won’t have a “That’s it!” moment for life on Mars. Maddening as it is, that’s the system. As the evidence grows, life becomes “more likely”. One day, maybe the evidence for life elsewhere will be “accepted”. If you’re a Not Lifer, you’re in for a surprise, not a shock.The idea of life “out there” will, I think, just gradually work its way into our heads as the evidence grows.
