Using tiny amounts of data and basic reasoning, Robin Hanson managed to figure out in the last few months:

1) Approx. how many expanding alien civs our Hubble volume will eventually contain (tens to hundreds)

2) When we will meet said expanding alien civs if we don't go extinct (500M to 2B years)

3) Where UFO aliens come from (yep, they're probably real), what they want (hint: it's not pretty), and what UFOs actually *are* (not what you think):
