The age of the universe and its vast number of stars suggests that extraterrestrial life should be common. If that’s the case, then where is everyone? In this infographic we explore some possibilities.

"Most people take it for granted that we have yet to make contact with an extraterrestrial civilization. Trouble is, the numbers don’t add up. Our Galaxy is so old that every corner of it should have been visited many, many times over by now. No theory to date has satisfactorily explained away this Great Silence, so it’s time to think outside the box. Here are eleven of the weirdest solutions to the Fermi Paradox."

"This one is similar to the Rare Earth hypothesis, but it suggests that the universe is still evolving and changing. Subsequently, the conditions to support advanced intelligence have only recently fallen into place. This is what cosmologist James Annis refers to as the phase transition model of the universe — what he feels is an astrophysical explanation for the Great Silence."
