In search of ET: Fear of what’s out there causes split among space scientists
I think the fears of some ET empire with Darth Vader (or similar) at the head is very misplaced.  Just think of the economics... &quot;let&#x27;s go exploit that world 10 LY away from us that we don&#x27;t fully understand and which will still takes us an insane amount of time to enslave and milk resources from!&quot;  What a scalable strategy given the size of space... one might even say it&#x27;s astronomically large! The resource consumption alone would be a very speculative bet by any would-be invaders... unless they were already close at hand, but we&#x27;re probably already too late to prevent that....<p>Naw... if there is any alien apocalypse to worry about it&#x27;s that some advanced civilization saw a life friendly Earth through their telescopes, perhaps millions of years ago, and decided to seed the place with their own bio-material and without any regard to what life might be there.  It won&#x27;t be a marching army, but a &quot;Terra forming&quot; project that may well already be underway if its happening at all, I would expect.
