Have you ever just sat back and thought about life? On this StarTalk explainer, Neil deGrasse Tyson and Chuck Nice investigate the physics of size and life.

You’ll learn why physics sets the rules, not biology. Neil explains how and why the laws of physics don’t manifest equally at all size scales. We explore the science of A Bug’s Life and what the creators got right about surface tension.

We discuss how our size as humans impacts what we can and cannot do. You’ll learn why you won’t find tiny creatures with really thick legs. We also discuss why whales can get so big. All that, plus, Neil tells us why Sylvester Stallone isn’t a believable rock climber in the movie Cliffhanger.
