42: The Answer to Almost Everything — Season 1, Episode 14: Are we alone in space?

Episode synopsis

The universe is vast. So vast that it defies the imagination. To the point that we find it strange that we "Earthlings" are the only living beings to inhabit it. What, then, is the probability that extraterrestrials exist? What might they look like? Finally, wouldn't their existence force us to rethink our place in the cosmos?

About 42: The Answer to Almost Everything

In a nod to Douglas Adams's "Hitchhiker's Guide to the Galaxy", where the figure 42 is the ultimate answer to all questions, 42 tries to provide the answers.
