Personal life Woo is a committed Christian, stating, "We talk about the fact that the universe is designed in this way and you can find all of these patterns; do you think that that's a coincidence? One of the things I love to point out is we call the universe the cosmos which means ordered and structured and designed, as opposed to chaos, and the reason why we can find these mathematical principles is because there was a Designer. We didn't just spring into being. It has immense beauty."
