Question: are there other life forms in the universe?

Pete Etchells answered on 6 Jul 2012:

We’ve not found any other forms of life out in space yet, but we’ve only really just started to look, and the universe is a pretty big place! Scientists and mathematicians have come up with theories and equations that suggest that it should be quite likely for life to exist elsewhere. And it would seem like a massive waste of space if Earth was the only planet that had life!
