Some researchers are so convinced that there are alien civilizations, they aren't asking "Is there life on other planets?" anymore. Instead they are asking, "How much extraterrestrial life is out there?"
In a recent paper published online by the International Journal of Astrobiology, a graduate student from the Royal Observatory, Edinburgh, in Scotland estimated there should be 361 advanced, stable civilizations in the Milky Way.
He based his theory on current observational knowledge of stars and planetary systems, as well as the assumption that life can only arise under a narrow set of initial conditions, according to Scientific American .
Not everyone in the field is buying the theory. "We have to admit that we're hugely ignorant of many of the pieces of information that we would need to know before we could realistically estimate the prevalence of intelligent life elsewhere in the galaxy," planetary scientist Ian Crawford of Birkbeck College at the University of London, told Scientific American.

Obama’s stealing the census from Congress has suddenly awakened and enraged the Republicans. Maybe this will arouse them as well to challenge Obama for stealing the Presidency itself. They surely know he is not an Article 2 “natural born citizen” (which is more than merely being a 14th Amendment “citizen”) by virtue of either Obama’s birth to a dad of Kenyan/British citizenship or birth in Kenya itself — as manifested by his unwillingness to supply his long form birth certificate now under seal.
