Tyler Cowen asks: If you thought non-hostile but highly disruptive aliens would arrive within the next ten years, which of your decisions would change? Should change? Earlier this year I wrote A list of solutions to the Fermi Paradox, so here are some thoughts, bearing in mind I suspect this is a Straussian question as well …

Wilczek also floats another idea - what if an alien civilization created a greenhouse effect to raise the temperature of a planet? For example, if extraterrestrials were currently researching Earth, they would likely notice the increased levels of carbon dioxide that are heating up our atmosphere. Similarly, we can looks for such signs around the exoplanets. An …

So there must be aliens. Why haven't we heard from them? (Read about the Fermi Paradox here.) This blog is a list of answers. I've summed up each one …
