How Far Can I See?

BBC World Service - CrowdScience, How Far Can I See?

Is it possible to see 15 quintillion miles away?

How far can I see? Why do men have nipples? Why do women feel the cold more than men? CrowdScience finds answers to these and more in this week’s multi-question special.

How far can you see? A few kilometres down the road? Or do you struggle to see past the end of your own nose? Well one listener thinks he might be able to see 15 quintillion miles away... but can he really? Marnie Chesterton and Bobbie Lakhera are on the case for this week’s multi-question human body special. As well as delving into the power of vision, they also discover why male mammals have nipples despite not needing to breastfeed, and Marnie puts herself in a giant refrigerator in the name of finding out why some people feel the cold more than others.
