Why do we need to do a campfire at night?
Perphaps this is not the right question: a better question would be “Why do we want to have a campfire at night?”. We don’t live in the wilderness anymore and, nowadays, using a campfire at night to keep beasts away is a very unusual need. Anyhow, our paleolithic ancestor still holds a place in our, let me say, deep thoughts brain area. The surface of this planet hosts many billions of humans, not just one hundred thousand as it did during that era but, sadly, the way we approach the world has not changed that much.

An artificial solar system made of six stars of the same kind placed to make a hexagon: this view is described in an old novel by Arthur C. Clarke (I’ve forgotten its title, sorry); the whole thing was made by an alien civilization before its extinction and, million years later, it still reminds the human explorer the greatness of its creators.
This story came back to my mind some weeks ago reading a well known article about what could survive our civilization in the long term (I lost the link, sorry again).
Our radio signal is larger than a century so its “sphere” will grow endlessly or something… but what about a more rock solid sign? I know we are not ready for an artificial solar system (we are on a budget and I guess some green warriors will try to stop the whole project :D) but what could we create, or what have we already created that will survive us in the long term? No, nuclear pollution doesn’t count :).
It’s funny that these kind of things are written on a blog whose name means temporariness :).
