DailyDirt: Out Of This World (And On To Others)

from the urls-we-dig-up dept

Astronomers only somewhat recently confirmed the existence of planets orbiting other stars like our own — in 1995. Since then, we’ve found nearly 2,000 exoplanets, and we’re honing in on more Earth-like planets that look like our own little world. Amateur astronomers have helped to identify a few exoplanets, and it looks like we’ll be able to find more and more of them. “You and I probably won’t be travelling to these planets – but our children’s children’s children could be.

Why leave it alone? Maybe we are but parasites and after we suck this world dry we will move on to the next one? Maybe instead of like all the movies portray, the aliens are the good guys and we will be the ones invading other worlds for their resources?

Or maybe we are stuck here; which in my mind isn’t such a bad place.

Leave it alone because planets are inherently dangerous places to live. The eventual home of all intelligent species is an artificial habitat in empty space. There are still a few hazards, even then, but far fewer than on a planet’s surface.

My own thought is that when a species reaches a certain level of technology, they migrate to space habitats while restoring the surface of the planet they are leaving – kind of turning the planet into a natural preserve. Perhaps they think that doing so also allows the planet a chance to produce another intelligent species.

Think about it – humans haven’t been around that long, and maybe a previous species already developed and then left Earth long ago, removing all signs they were here when they did so. Maybe in another hundred or so years, we’ll be in O’Neil stations while robots remove all signs of human habitation from the surface, leaving the Earth free for the next species.
