I came across this incredible article from livescience.com entitled "The 9 Biggest Mysteries in Physics"(click for link), as I was infosnacking on Twitter. It's a great article and really embodies where Physics is headed in the next 25 years, if we can even answer one of these questions with any degree of certainty. In this episode we discuss #3-1 in some detail, since as budding physicists, this are the monster questions you have to grapple with. I also realize that maybe the order that I've been passively heckling them about for the last 2 episodes may actually be decent. Good luck!
