When the Black Death ran rampant through cities in the Middle Ages, no one knew exactly how or why the awful disease spread. After many generations, we figured out that rat fleas and bacteria were to blame. It was a watershed moment for the power of science.
Centuries later, the brightest minds continue to investigate difficult, bewildering scientific questions every day. Yet even with artificial intelligence and brilliant minds connecting with more computing power than our species has ever known, we still don't have all of the answers. In fact, some people might argue that we're just now learning to ask the truly big questions.

What happens to us after we die? How did so much life appear on our planet when others seem devoid of any species at all? Who, if anyone, pulls the strings of our universe? Is it some all-powerful god in control or are there physical and mathematical principles driving the engine of our existence?
Sometimes, after centuries of missteps, we humans finally stumble into real answers to real questions, such as why diseases spread. Other times, we're left grasping into the darkness of our own ignorance and wondering what any of it really means. But humanity will keep trying to eliminate questions and give us the true answers.
