Manage episode 357119967 series 2892024
When it comes to life in the universe, there's no question. Considering the vastness of space, there must be. The question is where and when will we find it ... and will it be sentient or basic one-cell creatures? Will it be friendly or hostile? Will they kill us or will we kill them? Okay, actually there are lots of questions. Dr. Amy Williams is one of those looking for answers.
