42 is the everything according to "The Hitchhiker's Guide to the Galaxy" (Douglas Adams)
An excerpt from the book:
"a group of hyper-intelligent pan-dimensional beings demand to learn the Ultimate Answer to the Ultimate Question of Life, The Universe, and Everything from the supercomputer, Deep Thought, specially built for this purpose. It takes Deep Thought 7½ million years to compute and check the answer, which turns out to be 42. Unfortunately, The Ultimate Question itself is unknown."
My physics instructor in college always liked to tell us that the answer to everything is 42...the key is in figuring out the right units.
