“Science is the best tool we have by far, self-correcting, ongoing, applicable to everything. It has two rules. First: There are no sacred truths; all assumptions must be critically examined; arguments from authority are worthless. Second: Whatever is inconsistent with the facts must be discarded or revised. We must understand the Cosmos as it is and not confuse how it is with how we wish it to be.” —Carl Sagan
