By Erik Jones This is the second in a series of posts about learning on YouTube. Check out the first post here. Will we ever run out of new music? What if the Earth stopped spinning? Or what would happen if the Sun disappeared? These are the types of questions your ten year old self annoyingly asked adults, or that you still secretly Google while procrastinating on some big project. They are the big, fun questions you really are curious about but only bring up to friends after too many beers at 3 am. They are also the questions that are difficult to find satisfying in depth answers to.
