Where the conditions are right, life can arise. But what might the ‘right’ conditions be? Could the dark sector of our Universe be inhabited? That’s what Gautam from Delhi, India has been wondering. He points out that dark matter and dark energy make up around 95% of the Universe and the remaining segment is normal matter - the stuff we’re all made up of.

Together, they unpick what dark matter and dark energy are and test out some listener theories as to what these mysterious mediums might be. For instance, Yoseph from Ogden, USA questions whether black holes could account for the missing matter and it turns out, he might just be on to something…
