If you've ever looked up into the sky and wondered whether someone might be looking back, some scientists say you can stop wondering — because they're certain that alien lifeforms exist. This provocative position is explored on "Are We Alone?", a month-long series airing on the Science Channel. Theoretical physicist Michio Kaku says aliens are a sure thing: "How many stars are there out in the universe?" he asks, calculating the answer as "10 sextillion — that's one with 22 zeroes after it." More stars equal more planets equal more possibilities for extra-terrestrial life. "There definitely are aliens in outer space — they're out there." [Huffington Post]
