Who hasn't heard of xkcd? To me, it's one of the best things on the web and I'm sure many of you are a fan of it. But how many of you read xkcd: What If? It's basically a blog where Randall Munroe takes on absurd hypothetical questions and answers them with as much scientific rigor as possible. I started reading it just recently and I can't get enough of it! The answers are insightful and hilarious at the same time.
Here are some of my favorites:
Random Sneeze Call [This is the first one I read and it got me hooked!]
And many more...
To be honest, I loved every single one I read and I haven't finished reading them all. Here's the complete archive. Enjoy!
And you can even submit your own questions. Make them as absurd as possible and you never know, it might even get answered.
