Scientists observe the world, create hypotheses, make and test predictions. Their findings are checked before publication by other experts, in a process known as “peer review.” Science is not perfect. It’s a process, not a body of facts. History tells us that some of today’s scientific “truths” will inevitably turn out to be wrong, or only partially true.

Still, science leads to profound insights about the natural world that are as true as anything can be here at the beginning of the 21st century.
