Would A Smaller Earth Be More Like Mars Or Like Venus? [4K] | Size Matters | Spark

In this episode, Planet Earth shrinks to half its size, causing altitude sickness and a cosmic disaster. The sun gets as small as a sun can be, turning Earth into a frozen ice ball. We also see what happens to a man who shrinks to the size of a wasp. Along the way, we find out why small creatures seem to have superpowers, and learn why a smaller planet would mean Earth turning into Mars.
