Life on earth is asymmetrical, and we end with another significant example of asymmetry. As stated earlier, the Big Bang should have produced equal amounts of matter and antimatter, which would have immediately self-annihilated. That clearly did not happen—we are here! We owe our existence to a very small asymmetry between matter and antimatter. Life, the Universe, and Everything is not just a book by Douglas Adams—it is part of the chemistry of every bit of protein in our body.
