Scope

Even the smartest scientists don't have all the answers to every single question. This episode of Scope looks at hypothetical questions such as 'What if there were no spiders?', 'What if all the ice on Earth melted?', 'What if there were no robots?', 'What if you fell into a black hole?'. Using the theory of 'selection bias', Doctor Joel attempts to answer the question 'Does buttered toast always land buttered side down?'. More questions are addressed such as; 'Why do cats meow?', 'Why don't birds get electrocuted when they sit on a power line?', 'Why do we yawn?', 'Why does your stomach acid dissolve food but not your body?' and 'Why can geckos and bugs stick to the ceiling?'.
