EARTH

"The Blue Marble" is a famous photograph of the Earth taken on December 7, 1972, by the crew of the Apollo 17 spacecraft en route to the Moon at a distance of about 29,000 kilometres (18,000 mi). It shows Africa, Antarctica, and the Arabian Peninsula.

Why does the earth spin? Is the moon moving farther away from earth? What are the odds of winning the lottery twice in a row and of getting the same numbers twice? We take on these questions in this week's podcast as well as reveal the difference between blu-ray and DVD's, what will happen when the earth's magnetic poles flip, why certain materials are transparent, and if water changes composition when boiled. Plus, we investigate the potential for life in outer space.
