Glances, bases, hearts … That’s what I thought people stole. Who knew this too: https://en.wikipedia.org/wiki/Sand_theft
So, I don’t know how I missed this, but apparently we had an interstellar visitor a while back, ‘Oumuamua. I learned about it from this interview with the chairman of Harvard’s astronomy department. I’ve found myself thinking about what he said a lot, sitting at red lights and stuff. These excerpts should give the idea:
We have no way of knowing whether it’s active technology, or a spaceship that is no longer operative and is continuing to float in space. But if Oumuamua was created together with a whole population of similar objects that were launched randomly, the fact that we discovered it means that its creators launched a quadrillion probes like it to every star in the Milky Way.
If to judge by our own behavior, it seems to me that the likeliest explanation is that civilizations develop the technologies that destroy them …The technological window of opportunity might be very small. Sails like these are launched, but they no longer have anyone to broadcast back to.
My premise is cosmic modesty … there are more planets like Earth than there are grains of sand on all the shores of all the seas. Imagine a king who manages to seize control of a piece of another country in a horrific battle, and who then thinks of himself as a great, omnipotent ruler. And then imagine that he succeeds in seizing control of all the land, or of the entire world: It would be like an ant that has wrapped its feelers around one grain of sand on a vast seashore. It’s meaningless.
As quoth Nigel Tufnel: “It really puts perspective on things, though, doesn’t it?”
