UPDATE: We got a couple of things wrong when it comes to gravity (particularly that it has nothing to do with photons). Check out this video from TheGentlemanPhysicis (http://www.youtube.com/watch?v=4y-dFLZHb1c) in which our confusion is explained. We also did a whole video about gravitation in our series on the four fundamental forces of physics, which you can watch here: http://www.youtube.com/watch?v=yhG_ArxmwRM
Science is working tirelessly night and day to disprove its own theories about how the universe works (or at least, that’s what science thinks it’s doing). Hank tells us a quick history of how we came to create and adopt the scientific method and then gives us a vision of the future of science (hint: it involves a lot more computers and a lot less pipetting).
